.SUBTITLE ^AN ^INTRODUCTION TO THE ^^FORTRAN A\\LPHAMERIC ^SUBROUTINE ^PACKAGE
^^FASP, \A FORTRAN A\\LPHAMERIC ^SUBROUTINE ^PACKAGE, IS A PACKAGE
OF ^^FORTRAN \\SUBROUTINES WHICH PROVIDE ALPHAMERIC INPUT/OUTPUT
FEATURES NOT PROVIDED DIRECTLY BY ^^FORTRAN. M\\OST OF THE
SUBROUTINES IN THIS PACKAGE EITHER WRITE CHARACTERS WITH A MULTIPLE
OF AN ^A1 FORMAT, OR ELSE GENERATE, MANIPULATE OR INTERPRET
CHARACTERS WHICH THE CALLING PROGRAM HAS READ IN WITH OR WILL WRITE
OUT WITH A MULTIPLE OF AN ^A1 FORMAT. ^THE FOLLOWING TYPES OF
ROUTINES ARE INCLUDED IN THIS PACKAGE.

^THE AUTHOR REQUESTS THAT THE COMMENT LINES STATING HIS NAME BE
RETAINED IN THE ROUTINES AND PROGRAMS WHICH FORM THIS PACKAGE AND
WHICH ARE DESCRIBED IN THIS DOCUMENT.
.SKIP
^THE ROUTINES DESCRIBED IN THIS DOCUMENTATION WERE WRITTEN FOR
SPECIFIC APPLICATIONS IN WHICH THESE ROUTINES APPEAR TO PRODUCE THE
EXPECTED RESULTS. ^HOWEVER, ^^FASP \\INCLUDES OVER 6000 ^^FORTRAN
\\STATEMENTS, AND THE ROUTINES IN THE PACKAGE HAVE UP TO 37
ARGUMENTS EACH IN THEIR CALLING SEQUENCES. ^ANY PACKAGE OF THIS SIZE
AND COMPLEXITY WILL CONTAIN ERRORS, AND CANNOT PRODUCE REASONABLE
RESULTS FOR ALL POSSIBLE ILLOGICAL VALUES OF THE INPUT ARGUMENTS.
^NEITHER THE AUTHOR, NOR ^HARVARD ^UNIVERSITY, ASSUME ANY
RESPONSIBILITY FOR ERRORS IN THE DOCUMENTATION OF THIS PACKAGE, FOR
MALFUNCTIONS OF THE ROUTINES WITHIN THIS PACKAGE, OR FOR
DIFFICULTIES WHICH MAY ARISE IN THE USE OF THESE ROUTINES.
.SKIP
^THIS MANUAL CONTAINS A COLLECTION OF 1 LINE DESCRIPTIONS OF EACH OF
THE ROUTINES IN THIS PACKAGE, FOLLOWED BY A COLLECTION OF 1
PARAGRAPH DESCRIPTIONS OF EACH OF THE ROUTINES, AND FINALLY A
COLLECTION OF DETAILED MULTIPLE-PAGE DESCRIPTIONS OF EACH OF THE
ROUTINES. ^EACH OF THESE COLLECTIONS IS ARRANGED IN THE ALPHABETICAL
ORDER OF THE ROUTINE NAMES. ^EACH DETAILED DESCRIPTION CONTAINS A
SUMMARY OF THE PURPOSE OF THE ROUTINE, A LISTING OF THE ^^SUBROUTINE
\\STATEMENT AS FOUND IN THE ROUTINE AND OF THE ^^DIMENSION
\\STATEMENT IF ANY, AND A DESCRIPTION OF EACH OF THE VARIABLES AND
ARRAYS IN THE ORDER IN WHICH THEY APPEAR IN THE ARGUMENT LIST. ^A
FEW OF THE ROUTINES IN THIS PACKAGE WHICH HAVE ARGUMENT LISTS WHICH
INCLUDE ALL OF THE ARGUMENTS OF THE PRIMITIVES WHICH THEY CALL ARE
DESCRIBED IN THE DOCUMENTATION OF THESE PRIMITIVES, RATHER THAN
SEPARATELY SO AS TO PREVENT DUPLICATION OF THE DESCRIPTIONS OF THE
IDENTICAL ARGUMENTS. ^THE 1 PARAGRAPH DESCRIPTIONS SPECIFY THE
LOCATIONS OF THE DETAILED DESCRIPTIONS OF SUCH WRAPPER ROUTINES AND
SIMILARLY SPECIFY THE LOCATIONS OF THE DETAILED DESCRIPTIONS OF THE
REDUCED CAPABILITY VERSIONS WHICH ARE SUPPLIED AS ALTERNATIVES FOR
SOME OF THE ROUTINES. ^AT THE END OF THE DETAILED DESCRIPTION WILL
USUALLY BE FOUND A LISTING OF A PROGRAM WHICH CALLS THE ROUTINE AND
A LISTING OF A TYPICAL PROGRAM-USER DIALOG. ^SUCH CALLING PROGRAMS
RANGE FROM SIMPLE INTERACTIVE DEMONSTRATIONS TO THE PROTOTYPES OF
THE APPLICATION PROGRAMS FOR WHICH THE ROUTINES WERE WRITTEN.
.SKIP
^IN THE ARGUMENT LISTS OF MOST OF THE ROUTINES DESCRIBED IN THIS
DOCUMENTATION, INPUT ARGUMENTS WHICH ARE RETURNED UNCHANGED APPEAR
FIRST, ARGUMENTS WHICH ARE USED BOTH FOR INPUT TO THIS ROUTINE AND
FOR OUTPUT FROM THIS ROUTINE EITHER TO THE CALLING PROGRAM OR TO THE
SUBSEQUENT CALL TO THE SAME ROUTINE APPEAR NEXT, AND ARGUMENTS FOR
WHICH THE INPUT VALUES ARE IGNORED AND WHICH ARE USED ONLY FOR
OUTPUT APPEAR LAST. ^THE ARGUMENT LISTS OF A FEW OF THE OLDER
ROUTINES IN THIS PACKAGE ARE NOT ARRANGED IN THIS MANNER, BUT THESE
ARGUMENT LISTS ARE USUALLY SHORT ANYWAY. ^ARGUMENTS HAVING THE SAME
NAMES IN DIFFERENT ROUTINES OFTEN HAVE SIMILAR DEFINITIONS.
^HOWEVER, SUCH DEFINITIONS CAN VARY IN OBSCURE WAYS. ^FOR EXAMPLE,
THE ARGUMENT NAMED ^^LOWBFR \\IS RETURNED POINTING TO THE CHARACTER
TO THE RIGHT OF AN ILLEGAL CHARACTER BY ^^DASPAN \\AND ^^DANEXT,
\\BUT IS RETURNED POINTING TO THE ILLEGAL CHARACTER ITSELF BY MOST
OF THE OTHER ROUTINES.
.SKIP
^THE PROGRAMS AND ROUTINES IN THIS PACKAGE ARE WRITTEN IN MACHINE
INDEPENDENT ^^FORTRAN \\BUT DO REQUIRE THAT THE COMPILER SUPPORT THE
1^H NOTATION IN ^^DATA \\STATEMENTS TO DEFINE 1 CHARACTER PER ARRAY
LOCATION, AND THAT THE RUNTIME SYSTEM BE ABLE TO USE THE ^A1 FORMAT
TO READ A SINGLE CHARACTER INTO A SINGLE ARRAY LOCATION OR TO WRITE
OUT AN ARRAY LOCATION CONTAINING SUCH A SINGLE CHARACTER. ^THE FILL
CHARACTERS TO PAD TO THE FULL WORD SIZE OF THE PARTICULAR COMPUTER
BEING USED ARE OF NO CONCERN EXCEPT THAT THE FILL CHARACTERS
SUPPLIED DURING READING WITH AN ^A1 FORMAT MUST MATCH THOSE SUPPLIED
WHEN THE 1^H NOTATION IS USED IN ^^DATA \\STATEMENTS. ^IF THE
ROUTINES IN THIS PACKAGE ARE USED ON SOME ^^IBM 370 \\SYSTEMS IN
WHICH THE 1^H NOTATION IN ^^DATA \\STATEMENTS RESULTS IN PADDING
WITH ZERO CHARACTER CODES WHILE CHARACTERS READ WITH A MULTIPLE OF
AN ^A1 FORMAT ARE PADDED WITH SPACE CHARACTERS, THEN IT WILL BE
NECESSARY TO CHANGE THE CHARACTER DEFINITIONS IN THE ^^DATA
\\STATEMENTS IN THESE ROUTINES FROM 1^H NOTATION TO 4^H NOTATION AND
TO INSERT 3 EXTRA SPACES TO THE RIGHT OF EACH CHARACTER SO DEFINED.
.SKIP
^MOST OF THE ARGUMENTS OF THESE ROUTINES HAVE NAMES WHICH BEGIN WITH
THE LETTERS ^I THROUGH ^N AND MUST CONTAIN EITHER INTEGER VALUES OR
ELSE CHARACTERS WHICH HAVE EACH BEEN READ BY THE USE OF AN ^A1
FORMAT OR WHICH HAVE BEEN DEFINED USING A 1^H NOTATION. ^THOSE FEW
ARGUMENTS WHICH HAVE NAMES BEGINNING WITH THE LETTERS ^A THROUGH ^H
OR ELSE WITH THE LETTERS ^O THROUGH ^Z ARE USED FOR REAL VALUES.
^NONE OF THE MACHINE-INDEPENDENT ROUTINES IN THIS PACKAGE STORE MORE
THAN A SINGLE CHARACTER PER COMPUTER LOCATION. ^A FEW OF THE
MACHINE-DEPENDENT DEMONSTRATION PROGRAMS AND ROUTINES WHICH ARE
LISTED AS EXAMPLES IN THIS DOCUMENT USE SINGLE AND DOUBLE PRECISION
VARIABLES TO CONTAIN SEVERAL CHARACTERS WHICH HAVE BEEN PACKED INTO
INDIVIDUALLY ADDRESSABLE COMPUTER LOCATIONS, BUT NO SPECIAL NAMING
CONVENTIONS HAVE BEEN USED FOR THESE VARIABLES.
.SKIP
^MOST OF THE ROUTINES IN THIS PACKAGE WERE DEVELOPED USING THE
^^DEC\\SYSTEM-10 ^F40 COMPILER. ^THE ^^DIMENSION \\AND ^^DATA
\\STATEMENTS HAVE SINCE BEEN REORDERED TO CONFORM TO THE SOMEWHAT
STRICTER SEQUENCING RULES ENFORCED BY THE NEWER ^^DEC\\SYSTEM-10
^^FORTRAN-10 \\COMPILER AND THIS COMPILER HAS BEEN USED FOR ALL OF
THE MORE RECENT DEVELOPMENT OF THE PACKAGE. ^THE USE OF THE
^^FORTRAN-10 \\COMPILER HAS ALLOWED THE ^^DATA \\STATEMENT IN THE
^^DAFLAG \\ROUTINE WHICH DEFINES THE CHARACTERS 1^H[ AND 1^H] TO BE
CHANGED FROM OCTAL MACHINE WORD NOTATION TO ^HOLLERITH CHARACTER
NOTATION. ^THE OCTAL NOTATION ^^DATA \\STATEMENT HAS BEEN COMMENTED
OUT, BUT MUST BE RESTORED IF THIS ROUTINE IS TO BE COMPILED USING
THE ^F40 COMPILER. ^THE LOWER CASE LETTERS WHICH APPEAR IN
^HOLLERITH STRINGS IN A FEW OF THE ROUTINES WILL BE TRANSLATED INTO
UPPER CASE IF THE ^F40 COMPILER IS USED, BUT THIS WILL CAUSE NO
DIFFICULTY OTHER THAN THAT THE ROUTINES WILL THEN BE UNABLE TO
PROCESS LOWER CASE INPUT.
.SKIP
^ALTHOUGH THE ROUTINES IN THE PACKAGE USE THE 1^H ^HOLLERITH
NOTATION IN ^^DATA \\STATEMENTS TO DEFINE VARIABLES WHICH ARE TO BE
MATCHED AGAINST CHARACTERS WHICH THE CALLING PROGRAM HAS READ 1 TO A
COMPUTER STORAGE LOCATION USING A MULTIPLE OF AN ^A1 FORMAT, THE
ARRAY ARGUMENTS USED FOR PASSING CHARACTERS TO THE ROUTINES ARE NOT
USED FOR ANY OTHER NUMERIC INFORMATION SO THAT THE ROUTINES IN THIS
PACKAGE SHOULD BE EASILY CONVERTED TO THE CHARACTER CONVENTIONS OF
THE ^^FORTRAN77 \\STANDARDS. ^SIMILARLY, TO PERMIT SUBSCRIPT RANGE
CHECKING, ALL OF THE ARGUMENT LISTS INCLUDE SIZE INFORMATION FOR THE
ARRAY ARGUMENTS EVEN THOUGH THIS SIZE INFORMATION MAY NOT BE NEEDED
BY THE LOGIC OF THE ROUTINES. ^SINCE THE ^^FORTRAN77 \\STANDARDS
REQUIRE THE EXPLICIT PRESERVATION OF VALUES ACROSS CALLS TO A
PARTICULAR ROUTINE, ALL NON-DIMENSIONED VARIABLES AND ALL FIXED
DIMENSIONED ARRAYS WHICH CONTAIN VALUES WHICH ARE NEEDED BY THE
SUBSEQUENT CALL TO THE SAME ROUTINE BUT WHICH ARE NOT NEEDED BY THE
CALLING PROGRAM ARE PLACED INTO LABELED ^^COMMON, \\AND ALL VARIABLY
DIMENSIONED ARRAYS APPEAR IN THE ARGUMENT LISTS.
.SKIP
^THE ROUTINES IN THIS PACKAGE MAKE EXTENSIVE USE OF PUNCTUATION
CHARACTERS WHICH ARE NOT PART OF THE STANDARD ^^FORTRAN \\CHARACTER
SET. ^IN PARTICULAR, MANY OF THE ROUTINES IN ^^FASP \\USE THE
SEMICOLON TO SEPARATE STATEMENTS WHICH APPEAR TOGETHER ON A SINGLE
LINE, THE EXCLAMATION POINT TO INDICATE THAT THE CURRENT STATEMENT
IS COMPLETE WITH THE REMAINDER OF THE CURRENT LINE BEING TAKEN AS A
COMMENT, AND THE AMPERSAND TO INDICATE THAT THE CURRENT STATEMENT
CONTINUES ON THE NEXT LINE WITH THE REMAINDER OF THE CURRENT LINE
BEING TAKEN AS A COMMENT. ^IF THESE CHARACTERS ARE NOT AVAILABLE,
THEN IT WILL BE NECESSARY TO SELECT OTHER CHARACTERS WHICH CAN BE
USED FOR THESE PURPOSES AND TO CHANGE THE ^^DATA \\STATEMENTS
ACCORDINGLY. ^MOST OF THE ROUTINES IN THIS PACKAGE ACCEPT A
TABULATION (TAB) CHARACTER AS EQUIVALENT TO A SPACE CHARACTER. ^EACH
TEST FOR A TAB CHARACTER IS PRECEDED BY A TEST FOR A SPACE
CHARACTER, SO IT IS MERELY NECESSARY TO CHANGE THE TAB CHARACTERS IN
THE ^^DATA \\STATEMENTS TO SPACES IF THE COMPUTER SYSTEM UPON WHICH
THESE ROUTINES ARE USED DOES NOT INCLUDE THE TAB CHARACTER IN ITS
CHARACTER SET.
.SKIP
^THE ROUTINES NAMED ^^DACASE (\\THE LOWER CASE TO UPPER CASE
CONVERTER) AND ^^DAVERB (\\THE WORD INTERPRETER) EACH CONTAIN A LIST
OF THE LOWER CASE LETTERS AND A LIST OF THE CORRESPONDING UPPER CASE
LETTERS. ^THE LOWER CASE LETTERS ARE DEFINED BY ^^DATA \\STATEMENTS
TO BE IN THE ORDER 1^HA THROUGH 1^HZ WHICH ON THE ^^DEC\\SYSTEM-10
COMPUTER RESULTS IN THE ASSOCIATED INTEGER VALUES BEING SORTED INTO
AN INCREASING ORDER. ^IF THESE ROUTINES ARE USED UPON A COMPUTER
SYSTEM IN WHICH THE ALPHABETICAL ORDER OF THE LETTERS 1^HA THROUGH
1^HZ DOES NOT RESULT IN AN INCREASING ORDER FOR THE ASSOCIATED
INTEGER VALUES, THEN THE ^^DATA \\STATEMENTS WHICH DEFINE THE ARRAYS
WHICH CONTAIN THE LOWER CASE LETTERS SHOULD BE REWRITTEN SO THAT THE
VALUES ASSOCIATED WITH THE LETTERS WILL BE IN INCREASING NUMERICAL
ORDER, AND THEN THE ^^DATA \\STATEMENTS WHICH DEFINE THE
CORRESPONDING UPPER CASE LETTERS MUST BE REWRITTEN SO THAT THE LOWER
AND UPPER CASE VERSIONS OF EACH LETTER APPEAR IN LOCATIONS IN THE
RESPECTIVE ARRAYS HAVING THE SAME SUBSCRIPTS. ^IF THESE ROUTINES ARE
USED UPON A COMPUTER SYSTEM WHICH DOES NOT SUPPORT LOWER CASE
LETTERS THEN THE ARRAYS WHICH WOULD OTHERWISE CONTAIN THE LIST OF
LOWER CASE LETTERS AS WELL AS THE ARRAYS WHICH CONTAIN THE LIST OF
UPPER CASE LETTERS CAN EACH CONTAIN THE UPPER CASE LETTERS 1^H^A
THROUGH 1^H^Z IN ALPHABETICAL ORDER EVEN IF THIS ORDER IS NOT THE
NUMERICALLY SORTED ORDER.
.SKIP
^SINCE THE ROUTINES IN THIS PACKAGE ARE DESIGNED TO BE USABLE IN A
WIDE VARIETY OF APPLICATIONS, MANY OF THEIR ARGUMENT LISTS ARE LONG.
^IF ANY ONE ROUTINE IS TO BE CALLED SEVERAL TIMES WITHIN A
PARTICULAR PROGRAM, THEN THE WRITING OF SEPARATE ^^CALL \\STATEMENTS
IS BOTH ERROR PRONE AND CONSUMPTIVE OF MACHINE SPACE. ^IF THE
ARGUMENT LISTS IN THE VARIOUS CALLS WOULD BE SIMILAR THEN IT IS
OFTEN WORTHWHILE TO WRITE A SHORT WRAPPER ROUTINE HAVING A MINIMAL
ARGUMENT LIST CONSISTING ONLY OF THOSE ARGUMENTS WHICH WOULD DIFFER
IN VALUE FOR THE INDIVIDUAL CALLS. ^AN ERROR WHICH IS COMMONLY MADE
IN WRITING CALLS TO ROUTINES HAVING SUCH LONG ARGUMENT LISTS IS THE
OMISSION OF AN ARGUMENT. ^SUCH OMISSIONS CAN BE DETECTED BY
COMPARING THE NUMBER OF ARGUMENTS IN THE ^^CALL \\AND ^^SUBROUTINE
\\STATEMENTS, BUT CAN USUALLY BE PREVENTED BY WRITING THE ^^CALL
\\STATEMENTS WITH EXACTLY THE SAME NUMBER OF ARGUMENTS PER LINE AS
APPEAR IN THE ^^SUBROUTINE \\STATEMENTS. ^AN ERROR WHICH IS OFTEN
MADE WHEN USING THE ROUTINES WHICH PERMIT THE USER TO SPECIFY BY
NAME AND TO MANIPULATE THE VALUES OF ^^FORTRAN \\ARRAYS IS THE
FAILURE TO DECLARE THE ARRAY ARGUMENTS OF THESE ROUTINES IN A
^^DIMENSION \\STATEMENT IN THE CALLING PROGRAM SINCE THESE ARRAYS
USUALLY ARE NOT MANIPULATED BY THE CALLING PROGRAM ITSELF.

(^^DEC) \\COMPUTERS, NO EVALUATION OF THE COMPONENTS IS PERFORMED,
SO THIS ROUTINE COULD BE USED TO FIND THE PARTS OF SPECIFICATIONS

\\IN WHICH ^^NUMBER \\MERELY IMPLIES A LOCATION AT WHICH A NUMBER
MIGHT BE PRESENT, BUT WHICH COULD INSTEAD CONTAIN ANY SEQUENCE OF
PRINTING CHARACTERS OTHER THAN THE SEPARATION AND DELIMITER
CHARACTERS. ^ONLY ONE DEVICE FIELD, ONE NAME FIELD AND ONE BRACKETED
FIELD CAN APPEAR TOGETHER IN A SINGLE FILE SPECIFICATION. ^THE
DEVICE FIELD MUST APPEAR BEFORE THE NAME FIELD, BUT THE BRACKETED
FIELD CAN BE BEFORE, BETWEEN, OR AFTER THE DEVICE AND NAME FIELDS.
^THE CALLING PROGRAM IS ALSO INFORMED IF AN AT SIGN APPEARS ANYWHERE
WITHIN THE FILE SPECIFICATION OTHER THAN WITHIN A SWITCH FIELD.
^SWITCH FIELDS CONSISTING OF INITIAL SLASHES FOLLOWED BY WORDS
CONNECTED BY COLONS ARE REPORTED SEPARATELY FROM THE REST OF THE
FILE SPECIFICATION AND SEPARATELY FROM EACH OTHER BY SEPARATE CALLS
TO THIS ROUTINE. ^COMPLETE FILE SPECIFICATIONS CAN BE SEPARATED BY
COMMAS, SEMICOLONS OR EQUAL SIGNS. ^COMMENTS WHICH ARE OTHERWISE
IGNORED CAN APPEAR TO THE RIGHT OF EXCLAMATION POINTS AND AMPERSANDS.
.SKIP
^SPACES AND/OR TAB CHARACTERS CAN APPEAR TO EITHER SIDE OF THE ITEMS
ENCLOSED WITHIN THE BRACKETS, AND CAN APPEAR AFTER THE LEADING
SLASHES OF SWITCH FIELDS AND BOTH BEFORE AND AFTER THE CONNECTING
COLONS IN SWITCH FIELDS. ^THE CALLING PROGRAM CAN SPECIFY WHETHER
OTHER SPACES ARE TO TERMINATE THE FILE SPECIFICATION, OR ARE TO
TERMINATE A PARTICULAR FIELD WITHIN THE FILE SPECIFICATION OR ARE TO
MERELY TERMINATE A PARTICULAR COMPONENT WITHIN THE FIELD. ^IN A
BRACKETED FIELD, COMMAS ARE NOT NECESSARY BETWEEN ITEMS WHICH ARE
SEPARATED BY SPACES AND/OR TAB CHARACTERS PROVIDING THE ITEMS BEING

AN ITEM IN THE DEVICE FIELD WAS FOLLOWED BY THE CONNECTING

EXTRA ZERO. ^WHETHER AN EXTRA ZERO APPEARS WITHIN THE DESCRIPTION OF
THE BRACKETED FIELD IS INDEPENDENT OF WHETHER THE RIGHT BRACKET IS
PRESENT.

^TEXT STRINGS DELIMITED BY APOSTROPHES ARE RECOGNIZED ONLY WITHIN
THE SWITCH FIELDS. ^IF A TEXT STRING IS FOUND WHICH HAS NOT BEEN
PRECEDED BY A SLASH THEN THIS TEXT STRING IS TREATED AS THOUGH IT

THE TEXT STRING WOULD HAVE TO BE EVALUATED BY THE NEXT CALL TO THIS
ROUTINE. ^THE LOCATION OF A TEXT STRING AS RETURNED TO THE CALLING
PROGRAM IS THAT OF THE INITIAL APOSTROPHE, AND THE LENGTH OF THE
TEXT STRING INCLUDES THE INITIAL, BUT NOT THE FINAL, APOSTROPHE. ^IF
THE FINAL APOSTROPHE IS MISSING, THEN THE TEXT STRING IS ASSUMED TO
EXTEND THROUGH THE RIGHTMOST PRINTING CHARACTER IN THE BUFFER.
^WITHIN A TEXT STRING, TWO IMMEDIATELY ADJACENT APOSTROPHES INDICATE
A SINGLE APOSTROPHE WHICH IS TO BE INCLUDED WITHIN THE STRING. ^IF
TWO IMMEDIATELY ADJACENT APOSTROPHES ARE ENCOUNTERED WITHIN THE TEXT
STRING, THEN THE REMAINING PORTION OF THE STRING IS MOVED 1

ACCUMULATED AS AN INTEGER, THEN BE CONVERTED TO A REAL NUMBER AND
SHIFTED IF NECESSARY. ^^KONTRL \\IS THEN THE MAXIMUM NUMBER OF
DIGITS IN THE INTEGER. ^THE VALUE IS OUTPUT AS THE ARGUMENT ^^VALUE.
I\\F THE ITEM HAS MORE THAN ^^KONTRL \\DIGITS (NOT COUNTING LEFTMOST
ZEROES), THEN THE ENTIRE EVALUATION IS DONE AS A REAL NUMBER. ^THE
ADVANTAGE OF CALCULATING THE REAL VALUES IN INTEGER AS LONG AS THE
PRECISION OF THE COMPUTER IS NOT OVERFLOWED IS THAT THE CALCULATION
OF THE PORTION OF THE NUMBER RIGHT OF THE DECIMAL POINT IS MORE
EXACT. ^AS AN EXAMPLE, IF ^^KONTRL \\IS GREATER THAN OR EQUAL TO 4,
THEN THE NUMBER 33.33 CAN BE STORED AS THE INTEGER 3333, THEN BE
CONVERTED TO THE REAL VALUE 3333.0 AND DIVIDED BY 100.0 TO OBTAIN
THE FINAL ANSWER. ^IF IT MAKES NO DIFFERENCE WHETHER THE NUMBER
TYPED AS 33.33 HAS VALUE 33.33 OR 33.32999... THEN ^^KONTRL \\CAN BE

THE EXPONENT IS EVALUATED IN DECIMAL. ^THE VALUE OF THE OCTAL NUMBER
IS RETURNED AS THE ARGUMENT ^^IVALUE. I\\T MUST BE NOTED THAT
NUMBERS EVALUATED AS NEGATIVE OCTAL INTEGERS HAVE THE NEGATIVE OCTAL
INTEGER AS THEIR VALUE, NOT AS THEIR BIT REPRESENTATION IN COMPUTER
STORAGE. ^FOR EXAMPLE, ON A 36 BIT TWOS COMPLEMENT COMPUTER, THE
OCTAL NUMBER -400000000000 (WHICH COULD ALSO BE TYPED AS -4^E11 OR
-4^E+11 WHERE THE 11 AFTER THE ^E IS IN DECIMAL) IS REPRESENTED AS

^MANY INTERACTIVE PROGRAMS INTERPRET THE APPEARANCE OF A QUESTION
MARK AT THE START OF THE TEXT TYPED BY THE USER TO BE A REQUEST BY
THE USER FOR INFORMATION. ^HOWEVER, A QUESTION MARK APPEARING WITHIN
OR TO THE RIGHT OF AN INTELLIGIBLE USER RESPONSE SHOULD PROBABLY BE
TREATED THE SAME AS ANY OTHER UNKNOWN CHARACTER. ^THE ROUTINES
WITHIN THE ^^FASP \\PACKAGE DO NOT HAVE AVAILABLE TO THEM ANY
INFORMATION REGARDING THE LOCATION OF THE TEXT CURRENTLY BEING
PROCESSED RELATIVE TO THE TOTAL TEXT WITHIN THE BUFFER. ^THESE
ROUTINES DO NOT TREAT THE QUESTION MARK DIFFERENTLY THAN ANY OTHER
UNKNOWN OR ALPHABETIC CHARACTER SINCE THE INTERPRETATION OF THE
QUESTION MARK DEPENDS UPON ITS LOCATION RELATIVE TO THE TOTAL TEXT
WITHIN THE BUFFER RATHER THAN UPON THE LOCATION OF THE QUESTION MARK
RELATIVE TO THE TEXT FORMING A PARTICULAR STATEMENT WHICH MIGHT BE
DELIMITED BY SEMICOLONS.
.SKIP
^INITIAL QUESTION MARKS CAN, HOWEVER, BE IDENTIFIED BY THE ^^DAHELP
\\ROUTINE IMMEDIATELY AFTER A NEW LINE OF TEXT HAS BEEN READ BY THE
CALLING PROGRAM. ^^DAHELP \\REPORTS HOW MANY QUESTION MARKS WERE
FOUND AT THE START OF THE BUFFER, AND SPECIFIES THE BUFFER LOCATION
WHICH CONTAINS THE FIRST PRINTING CHARACTER WHICH IS NOT ITSELF A
QUESTION MARK. ^IF A QUESTION MARK IN NOT FOUND, THEN THE LOCATION
OF THE FIRST PRINTING CHARACTER CAN BE SUPPLIED TO THE OTHER
ROUTINES IN THE ^^FASP \\PACKAGE AS THE LOCATION IN THE BUFFER AT
WHICH THESE ROUTINES ARE TO BEGIN INTERPRETATION. ^THE CALLING
PROGRAM SHOULD ISSUE THE APPROPRIATE INFORMATIVE MESSAGE IF THE
FIRST PRINTING CHARACTER IS FOUND TO BE A QUESTION MARK, AND THEN,
IGNORING THE REMAINDER OF THE CURRENT CONTENTS OF THE BUFFER, SHOULD
ASK FOR AND ACCEPT A NEW RESPONSE FROM THE USER, AGAIN ASSURING THAT
THIS NEW MESSAGE DOES NOT ITSELF BEGIN WITH A QUESTION MARK BEFORE
RESUMING NORMAL PROCESSING. ^EITHER THE NUMBER OF QUESTION MARKS
FOUND ON A SINGLE LINE, OR ELSE THE NUMBER OF CONSECUTIVE LINES
FOUND TO START WITH QUESTION MARKS MIGHT BE USED TO SELECT THE

^THE ARGUMENTS WHICH APPEAR TO THE RIGHT OF THE COMMAND WORD CAN BE
POSSIBLY SIGNED NUMBERS, OR ALPHABETIC WORDS TO BE EVALUATED BY THE
CALLING PROGRAM, OR (QUOTED) TEXT STRINGS BEGUN AND TERMINATED
EITHER BY THE APOSTROPHE CHARACTER OR ELSE BY MATCHED PARENTHESES.
.SKIP
^THE SIGNED VALUE OF A NUMERIC ARGUMENT AND AN INDICATION OF ITS
SIGN, IF ANY, ARE BOTH RETURNED TO THE CALLING PROGRAM SO THAT THE
APPEARANCE OF A PLUS SIGN CAN, IF NECESSARY, BE TREATED DIFFERENTLY
THAN THE ABSENCE OF ANY SIGN. ^FOR EXAMPLE, AN UNSIGNED NUMBER MIGHT
INDICATE A LOCATION UPON A POSITIVE COORDINATE SCALE, BUT A NUMBER
PRECEDED BY A SIGN MIGHT INDICATE A RELATIVE SHIFT OR VECTOR.
^NUMBERS CAN BE SEPARATED BY SLASHES OR BY COLONS (THE 2 CHARACTERS
ARE EQUIVALENT) IF THEY ARE TO BE ASSOCIATED IN SOME MANNER. ^TWO
SUCH POSSIBLY SIGNED NUMBERS SEPARATED ONLY BY A SINGLE SLASH OR BY
A SINGLE COLON MIGHT INDICATE A RANGE. ^THREE POSSIBLY SIGNED
NUMBERS SEPARATED ONLY BY SLASHES OR BY COLONS MIGHT BE USED TO
INDICATE THE START OF A RANGE, THE INCREMENT, AND THE END OF THE
RANGE.
.SKIP
^A WORD APPEARING AS AN ARGUMENT OF A COMMAND MUST BEGIN WITH A
CHARACTER WHICH CANNOT START A NUMBER AND WHICH IS NOT ONE OF THE
DELIMITER CHARACTERS SUCH AS THE SPACE, TAB CHARACTER, SLASH, COLON,
SEMICOLON, EXCLAMATION POINT, COMMA, APOSTROPHE OR PARENTHESES.
^DIGITS CAN APPEAR ANYWHERE TO THE RIGHT OF THE LEADING CHARACTER OF
THE WORD, BUT THE OTHER PROHIBITED CHARACTERS WILL, IF ENCOUNTERED,
TERMINATE THE WORD. ^^DAHEST \\INDICATES TO THE CALLING PROGRAM THE
CHARACTER LOCATIONS AT WHICH THE WORD BEGINS AND ENDS.
.SKIP
^TEXT STRINGS DELIMITED BY THE APOSTROPHE CHARACTER CAN CONTAIN ANY
LEGAL ^^FORTRAN \\READABLE CHARACTERS. ^IF THE TEXT STRING IS TO
CONTAIN THE APOSTROPHE ITSELF, THEN THIS IS INDICATED BY 2
SUCCESSIVE APPEARANCES OF THE APOSTROPHE NEITHER OF WHICH IS TAKEN
TO BE THE STRING TERMINATOR. ^^DAHEST \\INDICATES TO THE CALLING
PROGRAM THE CHARACTER LOCATIONS AT WHICH THE TEXT INSIDE THE
DELIMITING APOSTROPHES BEGINS AND ENDS. ^IF THE TEXT STRING CONTAINS
APOSTROPHES INDICATED BY 2 APPEARANCES OF THE APOSTROPHE, THEN
^^DAHEST \\REMOVES THE EXTRA APOSTROPHE FROM THE STRING AND MOVES
THE POSITION OF THE RIGHTMOST POINTER 1 CHARACTER TO THE LEFT. ^IF
THE APOSTROPHE WHICH INDICATES THE RIGHT END OF THE STRING IS
MISSING, THEN THE TEXT STRING IS ASSUMED TO EXTEND THROUGH THE
RIGHTMOST PRINTING CHARACTER ON THE LINE.
.SKIP
^THE START OF A TEXT STRING CAN ALSO BE INDICATED BY A LEADING LEFT
OR RIGHT PARENTHESIS. ^STARTING WITH THE LEADING PARENTHESIS, A
LEVEL COUNT IS OBTAINED BY ADDING 1 FOR EACH LEFT PARENTHESIS WHICH
IS NOT PRECEDED BY AN APOSTROPHE, AND BY SUBTRACTING 1 FOR EACH
RIGHT PARENTHESIS WHICH IS NOT PRECEDED BY AN APOSTROPHE. ^THE TEXT
STRING THEN CONTINUES TO THE NEXT PARENTHESIS WHICH RETURNS THE
PARENTHETICAL LEVEL COUNT TO ZERO, OR THROUGH THE RIGHTMOST PRINTING
CHARACTER ON THE LINE IF A CLOSING PARENTHESIS IS NOT FOUND. ^THE
TEXT STRING INCLUDES EMBEDDED PARENTHESES IF THESE DO NOT RETURN THE
PARENTHETICAL LEVEL COUNT TO ZERO. ^IF AN APOSTROPHE IS ENCOUNTERED
WITHIN THE TEXT STRING, THEN THE APOSTROPHE IS RETAINED AND BOTH THE
APOSTROPHE AND THE CHARACTER TO ITS RIGHT ARE INCLUDED IN THE TEXT
STRING.
.SKIP
^ALTHOUGH ^^DAHEST \\DOES NOT REVEAL TO THE CALLING PROGRAM WHETHER
THE TEXT STRING STARTED TO THE RIGHT OF A LEADING APOSTROPHE OR OF A
LEFT OR A RIGHT PARENTHESIS, THE CALLING PROGRAM CAN EASILY
DETERMINE WHICH OF THESE THREE CHARACTERS APPEARS TO THE IMMEDIATE
LEFT OF THE CONTENTS OF THE TEXT STRING. ^IN THE APPLICATION FOR
WHICH ^^DAHEST \\WAS WRITTEN, TEXT STRINGS BEGUN BY APOSTROPHES
CONTAIN CHARACTERS TO BE HANDLED IN THE ORDER ENCOUNTERED, STRINGS
BEGUN BY LEFT PARENTHESES CONTAIN CHARACTERS TO BE INCLUDED IN A
CLASS, AND STRINGS BEGUN BY RIGHT PARENTHESES CONTAIN CHARACTERS TO
BE EXCLUDED FROM A CLASS.

^ONE, BUT ONLY ONE, OF THE THREE TYPES OF ARGUMENTS, WORDS OR
NUMBERS OR TEXT STRINGS, CAN BE USED MORE THAN ONCE AS AN ARGUMENT.
^IF THE TYPE OF ARGUMENT WHICH CAN BE REPEATED IS SPECIFIED BEFORE
THE FIRST ARGUMENT IS FOUND, EITHER BEING THE SAME FOR ALL COMMANDS,
OR ELSE BEING SPECIFIED SEPARATELY IN THE DICTIONARY FOR EACH
COMMAND, THEN ARGUMENTS OF THE OTHER TWO TYPES CAN APPEAR AT MOST
ONCE IN THE ARGUMENT LIST. ^IF THE REPEATABLE TYPE IS WORD OR TEXT
STRING, THEN A SET OF NUMBERS INDICATING A RANGE CAN STILL BE
SUPPLIED. ^IF THE REPEATABLE TYPE IS NUMERIC, THEN MORE THAN ONE SET
OF NUMBERS INDICATING RANGES WILL BE ACCEPTED. ^ALTERNATIVELY, THE
TYPE OF ARGUMENT WHICH CAN BE REPEATED CAN BE THE TYPE OF THE FIRST
ARGUMENT ENCOUNTERED, IN WHICH CASE ARGUMENTS OF THE OTHER TWO TYPES
ARE NOT ALLOWED IN THE ARGUMENT LIST.
.SKIP
^ANY NUMBER OF SPACES AND/OR TAB CHARACTERS CAN APPEAR BEFORE THE
COMMAND WORD AND BETWEEN THE COMMAND WORD AND ITS FIRST ARGUMENT.
^SUCCESSIVE ARGUMENTS CAN BE SEPARATED BY A SINGLE COMMA AND/OR BY
ANY NUMBER OF SPACES AND/OR TAB CHARACTERS. ^NO SEPARATING
CHARACTERS ARE NECESSARY IF THE LEADING CHARACTER OF AN ARGUMENT
INDICATES THAT IT CANNOT CONTINUE THE PRECEDING COMMAND WORD OR
PRECEDING ARGUMENT. ^A SINGLE COMMA APPEARING BETWEEN 2 ARGUMENTS OF
EITHER THE SAME OR OF DIFFERENT TYPES MERELY INDICATES THE
SEPARATION BETWEEN THE ARGUMENTS, AND IS ENTIRELY EQUIVALENT TO ONE
OR MORE SPACES AND/OR TAB CHARACTERS. ^TWO COMMAS, POSSIBLY
SEPARATED BY SPACES AND/OR BY TAB CHARACTERS, INDICATE A MISSING
ARGUMENT OF THE REPEATABLE TYPE. ^A COMMA APPEARING IMMEDIATELY
(EXCEPT FOR OPTIONAL SPACES AND/OR TABS) AFTER THE COMMAND WORD IS
TAKEN TO INDICATE THAT THE FIRST ARGUMENT OF THE REPEATABLE TYPE IS
MISSING. ^FOR EXAMPLE, IN THE STATEMENTS

^AN INTERACTIVE PROGRAM WHICH WAS USED TO PROVE THE SUFFICIENCY OF
THE NAMED ARRAY MANIPULATION ROUTINES FOR A PARTICULAR APPLICATION
IS LISTED ON THE FOLLOWING PAGES TOGETHER WITH A DIALOG BETWEEN THE
USER AND THE PROGRAM. ^ALSO LISTED IS A SHORTER NONINTERACTIVE
SUPPORT PROGRAM WHICH CONSTRUCTS A DATA BASE FOR THE INTERACTIVE
PROGRAM.
.SKIP
^THE INTERACTIVE PROGRAM ALLOWS THE USER TO EXAMINE AND CHANGE THE
VALUES IN 6 DIFFERENT GROUPS OF SIMULATED ARRAYS. ^EACH DATA FILE
READ AND WRITTEN BY THE PROGRAM STORES THE VALUES OF A SINGLE GROUP
OF SIMULATED ARRAYS. ^IN THOSE CASES WHERE DIFFERENT VERSIONS OF THE
VALUES OF A SINGLE GROUP ARE MAINTAINED, THESE VERSIONS ARE SELECTED
BY ^^GLOBAL \\AND ^^LOCAL \\IDENTIFICATION NUMBERS TYPED BY THE
USER. ^THE ^^GLOBAL \\NUMBER SELECTS THE FINAL CHARACTER OF THE FILE
NAME. ^THE ^^LOCAL \\NUMBER SELECTS A RECORD WITHIN THE FILE. ^IF
THE USER TYPES THE NAME OF AN ARRAY WHICH DOES NOT VARY ACCORDING TO
EITHER ^^GLOBAL \O\R LOCAL \\NUMBERS, THEN THESE NUMBERS ARE
IGNORED. ^TO SELECT A NEW ^^LOCAL \\NUMBER, THE USER TYPES AN EMPTY
LINE IN RESPONSE TO THE REQUEST FOR ANOTHER ARRAY NAME. ^TO SELECT A
NEW ^^GLOBAL \\NUMBER, THE USER TYPES AN EMPTY LINE (OR ZERO) IN
RESPONSE TO THE REQUEST FOR A NEW ^^LOCAL \\NUMBER. ^WHEN THE
CONTENTS OF A NEW RECORD MUST BE READ, THE CONTENTS OF PREVIOUS
RECORD ARE FIRST WRITTEN BACK INTO THE FILE IF THESE VALUES HAVE
BEEN CHANGED BY THE USER. ^THE PROGRAM REPORTS TO THE USER WHEN
FILES ARE OPENED AND WHEN RECORDS ARE READ AND WRITTEN.
.SKIP
^THE VALUES INITIALLY STORED IN THE DATA FILES ARE MERELY THE
SEQUENCE NUMBERS OF THE LOCATIONS CONTAINING THE VALUES RELATIVE TO
ALL LOCATIONS STORING VALUES FOR THAT PARTICULAR GROUP OF SIMULATED
ARRAYS. ^IN THE ASSIGNMENT OF THESE VALUES, THE ^^LOCAL \\NUMBER IS
VARIED MORE RAPIDLY THAN THE ^^GLOBAL \\NUMBERS, I.E. WHERE
DIFFERENT VERSIONS ARE STORED FOR BOTH ^^LOCAL \\AND ^^GLOBAL
\\NUMBERS, THE COUNTS CONTINUE IN THE RECORD SELECTED BY THE NEXT
HIGHER ^^LOCAL \\NUMBER, AND WHEN THE END OF THE FILE HAS BEEN
REACHED, ARE CONTINUED IN THE FILE SELECTED BY THE NEXT HIGHER
^^GLOBAL \\NUMBER. ^TO AID THE USER IN CHECKING THE OPERATION OF THE
PROGRAM, THE NAME OF EACH SIMULATED ARRAY IS CONSTRUCTED OF A SINGLE
ALPHABETIC LETTER FOLLOWED BY THE DIGITS OF THE NUMBER WHICH IS THE
SUBSCRIPT OF THE BUFFER LOCATION WHICH CONTAINS THE START OF THE
SIMULATED ARRAY, AND EACH GROUP OF SIMULATED ARRAYS WHICH CAN VARY
BY EITHER ^^GLOBAL \O\R LOCAL \\NUMBERS CONTAINS A MULTIPLE OF 1000
LOCATIONS.

^^KONTRL#=#-1, \\THE NUMBER (OR SERIES OF NUMBERS) IN THE ^^IBUFFR
\\ARRAY IS AN OCTAL INTEGER (OR A SERIES OF OCTAL INTEGERS). ^THE
NUMBER CAN BE TYPED WITH A DECIMAL POINT AND/OR WITH AN EXPONENT.
^HOWEVER, THE NUMBER FOLLOWING THE LETTER ^E OF THE EXPONENT IS
EVALUATED IN DECIMAL. ^THE VALUE OF THE OCTAL NUMBER IS RETURNED AS
THE ARGUMENT ^^NEWVAL. I\\T MUST BE NOTED THAT NUMBERS EVALUATED AS
NEGATIVE OCTAL INTEGERS HAVE THE NEGATIVE OCTAL INTEGER AS THEIR
VALUE, NOT AS THEIR BIT REPRESENTATION IN COMPUTER STORAGE. ^FOR
EXAMPLE, ON A 36 BIT TWOS COMPLEMENT COMPUTER, THE OCTAL NUMBER
-400000000000 (WHICH COULD ALSO BE TYPED AS -4^E11 OR -4^E+11 WHERE
THE 11 AFTER THE ^E IS IN DECIMAL) IS REPRESENTED AS THE BIT PATTERN
HAVING OCTAL NOTATION 400000000000 AND THE OCTAL NUMBER
-377777777777 IS REPRESENTED BY THE BIT PATTERN 400000000001.
.INDENT -2
=#0, THE NUMBER (OR SERIES OF NUMBERS) IN THE ^^IBUFFR \\ARRAY IS A
DECIMAL INTEGER (OR A SERIES OF DECIMAL INTEGERS). ^THE NUMBER CAN
BE TYPED WITH A DECIMAL POINT (FOR EXAMPLE 1.23^K OR 1.23^E3 EQUALS
1230), BUT IS STORED AS AN INTEGER, AND IS OUTPUT AS ARGUMENT
^^NEWVAL. A\\NY DECIMAL INTEGER WHICH THE COMPUTER CAN REPRESENT CAN
BE EVALUATED. ^THIS INCLUDES, ON TWOS COMPLEMENT COMPUTERS, THE
LARGEST NEGATIVE NUMBER THE ABSOLUTE VALUE OF WHICH CANNOT BE
STORED. ^ON THE ^^PDP10, \\A 36 BIT COMPUTER WITH TWOS COMPLEMENT
NOTATION, THE RANGE OF DECIMAL INTEGERS IS -34359738368 THROUGH
34359738367 (THE OCTAL NOTATION OF THE BIT PATTERNS BEING
400000000000 THROUGH 377777777777).
.INDENT -2
=#1 OR GREATER, THE NUMBER (OR SERIES OF NUMBERS) IN THE ^^IBUFFR
\\ARRAY IS A REAL NUMBER (OR A SERIES OF REAL NUMBERS). ^IF
POSSIBLE, THE REAL NUMBER WILL BE ACCUMULATED AS AN INTEGER, THEN BE
CONVERTED TO REAL AND SHIFTED IF NECESSARY. ^^KONTRL \\IS THEN THE
MAXIMUM NUMBER OF DIGITS IN THE INTEGER. ^THE VALUE IS OUTPUT AS THE
ARGUMENT ^^VALNEW. I\\F THE ITEM HAS MORE THAN ^^KONTRL \\DIGITS,
THEN THE ENTIRE EVALUATION IS DONE AS A REAL NUMBER. ^THE ADVANTAGE
OF CALCULATING THE REAL VALUES IN INTEGER AS LONG AS THE PRECISION
OF THE COMPUTER IS NOT OVERFLOWED IS THAT THE CALCULATION OF THE
PORTION OF THE NUMBER RIGHT OF THE DECIMAL POINT IS MORE EXACT. ^AS
AN EXAMPLE, IF ^^KONTRL \\IS GREATER THAN OR EQUAL TO 4, THEN THE
NUMBER 33.33 CAN BE STORED AS THE INTEGER 3333, THEN BE CONVERTED TO
THE REAL VALUE 3333.0 AND DIVIDED BY 100.0 TO OBTAIN THE FINAL
ANSWER. ^IF IT MAKES NO DIFFERENCE WHETHER THE NUMBER TYPED AS 33.33
HAS VALUE 33.33 OR 33.32999... THEN ^^KONTRL \\CAN BE GIVEN THE
VALUE 1.
.SKIP
.INDENT -9
^^SLACK##=#\\THE FRACTION OF THE INCREMENT OF A SERIES EXPRESSED IN
SLASH OR COLON NOTATION, IF ^^KONTRL \\IS GREATER THAN ZERO, BY
WHICH THE RETURNED VALUE OF THE ARGUMENT NAMED ^^VALNEW \\CAN EXCEED
THE UPPER BOUND AND STILL BE CONSIDERED TO BE WITHIN THE SERIES.
^^SLACK \\IS NECESSARY BECAUSE OF THE IMPRECISION OF CALCULATIONS
INVOLVING REAL NUMBERS. ^FOR EXAMPLE, IF THE USER WISHED TO HAVE THE
INCREMENT BE 0.666... BETWEEN A LOWER BOUND OF 3.0 AND AN UPPER
BOUND OF 5.0, HE MIGHT TYPE 3/.667/5 AND EXPECT THAT THE NUMBERS
3.000, 3.667, 4.333, AND 5.000 WOULD BE INCLUDED WITHIN THE SERIES,
WHILE, ACTUALLY, THE NUMBER NEAR 5.00 WOULD BE CALCULATED TO BE
5.001 AND WOULD THEREFORE BE OUTSIDE THE SERIES. ^ALTHOUGH ^^SLACK
\\CAN BE SET TO ZERO, A VALUE OF ABOUT 0.01 IS RECOMMENDED. ^IN THE
ABOVE EXAMPLE, ^^SLACK=0.01 \\WOULD CAUSE THE ACTUAL UPPER BOUND TO
BE 5.00667 SO THAT THE NUMBER CALCULATED NEAR THE UPPER BOUND WOULD
BE INCLUDED WITHIN THE SERIES. ^^SLACK \\SHOULD ALMOST CERTAINLY
NEVER EXCEED 0.5 SINCE LARGER VALUES WOULD OFTEN LEAD TO THE
INCLUSION OF VALUES NOT MEANT BY THE USER. ^^SLACK \\IS IGNORED IF
^^KONTRL \\IS LESS THAN OR EQUAL TO ZERO.

^^DAPAIR \\RETURNS TO THE CALLING PROGRAM A PAIR OF VALUES
REPRESENTED BY THE CHARACTERS IN AN INPUT BUFFER READ BY THE CALLING
PROGRAM WITH A MULTIPLE OF AN ^A1 FORMAT. ^THE PAIR OF VALUES IS
ASSUMED TO CONSIST OF AN INDEX (OR A SUBSCRIPT), WHICH IS
REPRESENTED FIRST IN THE INPUT BUFFER, AND OF A VALUE TO BE
ASSOCIATED WITH THIS INDEX. ^IF SUBSEQUENT CALLS TO THIS ROUTINE ARE
TO ASSIGN A SEQUENCE OF VALUES WITH A CONSTANT INCREMENT TO EITHER
THE INDEX OR THE ASSOCIATED VALUE, THEN THE REPRESENTATION OF A
SINGLE INDEX OR OF A SINGLE RANGE OF INDEXES IS FOLLOWED BY THE
REPRESENTATIONS OF THE SEVERAL ASSOCIATED VALUES AND/OR OF THE
SEVERAL RANGES OF ASSOCIATED VALUES. ^IF BOTH NUMBERS ARE SPECIFIED
AS MEMBERS OF RANGES, THEN THE FIRST CALL TO THIS ROUTINE RETURNS
THE FIRST VALUE OF THE FIRST RANGE AS THE INDEX AND THE FIRST VALUE
OF THE SECOND RANGE AS THE ASSOCIATED VALUE, THE SECOND CALL TO THIS
ROUTINE RETURNS THE SECOND VALUE OF THE FIRST RANGE AS THE INDEX AND
THE SECOND VALUE OF THE SECOND RANGE AS THE ASSOCIATED VALUE, AND SO
ON. ^IF THE RANGE OF INDEXES IS EXHAUSTED PRIOR TO THE GENERATION OF
THE FINAL MEMBER OF THE RANGE OF ASSOCIATED VALUES, THEN THE FINAL
VALUE OF THE INDEX IS RETURNED UNCHANGED WITH THE SUBSEQUENT
ASSOCIATED VALUES, BUT THE CALLING PROGRAM IS INFORMED OF THIS
CONDITION AND CAN ADJUST THE INDEX AS NECESSARY. ^ONCE BOTH THE
RANGE OF INDEXES AND THE CURRENT RANGE OF ASSOCIATED VALUES HAVE
BEEN EXHAUSTED, THEN THE FOLLOWING REPRESENTATION OF A SINGLE NUMBER
OR OF A RANGE OF NUMBERS CAN SPECIFY THE INDEXES OF A SUBSEQUENT
PAIR, OR CAN SPECIFY ADDITIONAL VALUES TO BE ASSOCIATED WITH THE
SAME FINAL INDEX.
.SKIP
^SPACES AND/OR TABS ARE ALLOWED BETWEEN THE REPRESENTATIONS OF
NUMBERS AND/OR OF NUMBER RANGES. ^THE CALLING PROGRAM CAN PROHIBIT
THE APPEARANCE OF PRINTING CHARACTERS BETWEEN THE REPRESENTATIONS OF
THE INDEX AND ITS ASSOCIATED VALUE, OR BETWEEN THE REPRESENTATIONS
OF SUBSEQUENT ASSOCIATED VALUES, IN WHICH CASE A COMMA INDICATES
THAT THE FOLLOWING NUMBER IS TO BE TAKEN AS A NEW INDEX, OR ELSE THE
CALLING PROGRAM CAN ALLOW COMMAS BETWEEN THE INDEX AND THE
ASSOCIATED VALUE OR BETWEEN SUBSEQUENT ASSOCIATED VALUES, IN WHICH
CASE 2 ADJACENT COMMAS INDICATE A MISSING ASSOCIATED VALUE.
.SKIP
^THE RANGES OF VALUES TO BE ASSIGNED TO THE INDEXES OR TO THE
ASSOCIATED VALUES CAN BE SPECIFIED IN EITHER SLASH OR COLON OR
ASTERISK NOTATIONS. ^IN ASTERISK NOTATION, A VALUE TO BE REPEATED A
GIVEN NUMBER OF TIMES IS PRECEDED BY THE NUMBER OF TIMES AND AN
ASTERISK. ^IN SLASH OR COLON NOTATION (THE 2 CHARACTERS ARE
EQUIVALENT), A VALUE WHICH IS TO START AT A SPECIFIED INITIAL VALUE,
THEN BE VARIED UNTIL IT REACHES A FINAL BOUND IS EXPRESSED AS THE
INITIAL VALUE, THE INCREMENT BY WHICH THE VALUE IS TO BE VARIED, AND
THE FINAL BOUND SEPARATED BY SLASHES OR BY COLONS. ^IF EITHER THE
INITIAL VALUE OR THE FINAL BOUND IS MISSING IN SLASH OR COLON
NOTATION, THEN THE MISSING VALUE IS ASSUMED TO BE ZERO. ^IF THE
INCREMENT IS NOT INCLUDED IN SLASH OR COLON NOTATION, THEN THE
INCREMENT IS ASSUMED TO BE 1 AND ONLY A SINGLE SLASH OR A SINGLE
COLON IS NEEDED TO SEPARATE THE INITIAL VALUE AND THE FINAL BOUND.

NEXT PAIRS RETURNED COULD BE 3 AND 8, 3 AND 9, 3 AND 10, AND THEN 4
APPEARANCES OF 3 AND 11. ^THE ROUTINE COULD INSTEAD INFORM THE
CALLING PROGRAM THAT A NEW INDEX WAS FOUND BUT NOT EVALUATED, THEN
SUBSEQUENT CALLS WOULD RETURN THE PAIRS 8 AND 11, 9 AND 11, 10 AND
11, AND A FINAL UNCHANGED 10 AND 11. ^A SEMICOLON (OR A COMMA IF NOT
ALLOWED BETWEEN ADJACENT ASSOCIATED VALUES) APPEARING BETWEEN THE 7
AND 8 WOULD FORCE THE LATTER INTERPRETATION, SINCE THE APPEARANCE OF
A SEMICOLON (OR OF A COMMA IF NOT ALLOWED BETWEEN ADJACENT
ASSOCIATED VALUES) CAUSES THE FOLLOWING NUMBER TO BE INTERPRETED AS
THE INDEX OF A SUBSEQUENT PAIR.

^^DAPLAT \\IS A ^^FORTRAN \\SUBROUTINE WHICH CONSTRUCTS PRINTABLE
PLOTS HAVING PROPORTIONS WHICH ARE SELECTED BY THE CALLING PROGRAM.
^EACH PLOT CAN CONTAIN ONE OR MORE CURVES AND EACH CURVE CAN BE
REPRESENTED BY ITS OWN ALPHABETIC LETTER. ^POINTS ON A CURVE CAN
OPTIONALLY BE CONNECTED EITHER BY ASTERISKS OR BY SOME ALPHABETIC
LETTER WHICH NEED NOT BE THE SAME AS THAT USED TO REPRESENT THE
POINTS THEMSELVES. ^IF PLOTTING POINTS NOT CONNECTED BY LINES, A PIN
MAP CAN BE SIMULATED BY USING THE CLOSEST EMPTY LOCATION IF THE
LOCATION REPRESENTING THE POINT IS ALREADY IN USE.
.SKIP
^THE PLOT CAN BE RULED WITH GRID LINES AT EVENLY SPACED INTERVALS
ACROSS THE WIDTH AND HEIGHT OF THE PLOT. ^NUMBERS PRINTED ALONGSIDE
THE PLOT ARE REPRESENTED WITH 5 SIGNIFICANT DIGITS, BUT WITH
SUPPRESSION OF RIGHTMOST ZEROES BEYOND THE DECIMAL POINT. ^IF THE
NUMBER CANNOT BE PRINTED IN FLOATING POINT FORM, THE NUMBER IS
REPRESENTED IN SCIENTIFIC NOTATION INSTEAD.
.SKIP
^IF TWO OR MORE DIFFERENT ALPHABETIC LETTERS ARE TO APPEAR IN THE
SAME LOCATION IN THE PRINTED PLOT, AN AMPERSAND WILL APPEAR INSTEAD.
^HOWEVER, IF THE LINE SEGMENTS CONNECTING POINTS ARE TO BE FORMED
FROM A DIFFERENT LETTER THAN THE LETTER REPRESENTING THE POINTS
THEMSELVES, THEN BOTH OF THESE LETTERS, WHERE USED FOR PREVIOUS
CURVES OR WHERE USED ELSEWHERE ON THE CURRENT CURVE, ARE NOT CHANGED
TO AMPERSANDS BY COINCIDENCE WITH THE PRESENT CURVE. ^POINTS AND
LINES WHICH ARE FORMED FROM ASTERISKS CAN BE SELECTED EITHER TO BE
SUPERSEDED BY (BE DOMINATED BY) ANY OTHER CHARACTERS, OR ELSE TO
SUPERSEDE (BE DOMINANT OVER) ANY OTHER CHARACTERS. ^THE CHARACTER
SET AND DOMINANCE RULES CAN BE CHANGED BY THE CALLING PROGRAM IF
NECESSARY.
.SKIP
^WHEN LINE SEGMENTS ARE FORMED FROM DIFFERENT LETTERS THAN ARE USED
TO REPRESENT POINTS, AND WHEN THESE LETTERS VARY FROM ONE CURVE TO
THE NEXT, THEN THE ORDER IN WHICH OVERLAPPING CURVES ARE SPECIFIED
CAN CHANGE WHICH LOCATIONS OF THE PLOT CONTAIN AMPERSANDS. ^FOR
EXAMPLE, IF WE SUPERIMPOSE THE HORIZONTAL AND VERTICAL LINE PATTERNS
SHOWN BELOW (ASSUMING THAT THE ASTERISKS ARE DOMINATED BY ALL OTHER
CHARACTERS)

T\\HE IMPORTANT DIFFERENCES BETWEEN THE ABOVE 2 PLOTS ARE AT ^X=2,
^Y=8 AND AT ^^X=4, Y=6. T\\HE CHOICE OF WHETHER OR NOT TO PLACE AN
AMPERSAND AT A PARTICULAR LOCATION ALONG THE REPRESENTATION OF A
CURVE MUST BE MADE BY COMPARING THE 2 LETTERS BEING USED FOR THE
CURVE WITH THE LETTER IF ANY ALREADY OCCUPYING THAT LOCATION. ^IN
THE LEFT PLOT ABOVE, THE HORIZONTAL LINE SEGMENT FORMED OF ^B'S WAS
SPECIFIED BEFORE THE VERTICAL LINE OF ^C'S. ^WHEN THE POINT OF
INTERSECTION WAS REACHED, THE ^B ALREADY ON THE PLOT WAS NOT FOUND
TO MATCH EITHER THE ^D'S BEING USED FOR THE CURRENT POINTS OR THE
^C'S BEING USED FOR THE CONNECTING LINE SEGMENTS SO THE ^B WAS
CHANGED TO AN AMPERSAND. ^IN THE RIGHT PLOT ABOVE, THE VERTICAL LINE
OF ^C'S WAS SPECIFIED BEFORE THE HORIZONTAL LINE OF ^B'S. ^WHEN THE
INTERSECTION WAS REACHED, THE ^C ALREADY ON THE PLOT WAS FOUND TO
MATCH ONE OF THE LETTERS ^B AND ^C BEING USED TO REPRESENT THE
CURRENT CURVE. ^SINCE A LINE SEGMENT RATHER THAN A POINT WAS BEING
CONSTRUCTED AT THE INTERSECTION, THE MATCHING CHARACTER ALREADY ON
THE PLOT WAS LEFT UNCHANGED. ^IF A POINT WAS BEING CONSTRUCTED AT
THE INTERSECTION INSTEAD OF A LINE SEGMENT, THEN THE CHARACTER ON
THE PLOT WOULD HAVE BEEN CHANGED TO THE CHARACTER BEING USED TO

^THE PROPORTIONS OF THE GRID SUPERIMPOSED UPON THE PLOT AREA BY THE
^^DAPLAT \\ROUTINE MUST BE SPECIFIED BY THE CALLING PROGRAM. ^THE
NUMBERS WHICH ARE PRINTED BESIDE AND BELOW THE PLOT MERELY REPRESENT
THE DATA UNIT COORDINATES PLOTTED AT THE CENTERS OF THE COLUMNS AND
LINES WHICH BEAR GRID LINES. ^THE RANGE OF DATA UNIT COORDINATES
REPRESENTED BY THESE SCALES CAN BE DIFFICULT TO INTERPRET IF THE
CALLING PROGRAM HOLDS THE GRID PROPORTIONS CONSTANT WHILE ATTEMPTING
TO OBTAIN THE MAXIMUM RESOLUTION BY ADJUSTING THE MINIMUM AND
MAXIMUM COORDINATES TO SPREAD THE CURVES ACROSS THE FULL WIDTH OR
HEIGHT OF THE PLOT. ^^DAPLAT \\CANNOT ITSELF CALCULATE THE GRID
PROPORTIONS WHICH WOULD PRODUCE A MINIMUM NUMBER OF NONZERO DIGITS
IN EACH SCALE NUMBER. ^IF PREDETERMINED GRID SPACINGS AND OFFSETS
ARE NOT NECESSARY, THEN THE ROUTINE ^^DAGRID \\CAN BE CALLED ONCE
FOR EACH SCALE BEFORE THE DATA IS PLOTTED TO SELECT THE GRID

^A SINGLE CALL TO ^^DARANK \\INTERPRETS AN ARRAY READ BY THE CALLING
PROGRAM WITH A MULTIPLE OF AN ^A1 FORMAT AND RETURNS THE DECIMAL
INTEGER VALUES REPRESENTED BY THIS ARRAY. ^THE RETURNED VALUES ARE
SORTED INTO EITHER INCREASING OR DECREASING ORDER AND DO NOT INCLUDE
DUPLICATE VALUES. ^IF MORE VALUES ARE REPRESENTED THAN CAN BE STORED
IN THE ARRAY PROVIDED BY THE CALLING PROGRAM FOR RETURNING THESE
VALUES, THEN EITHER THE SMALLEST OR THE LARGEST VALUES CAN BE
DISCARDED.
.SKIP
^NUMBERS CAN BE SEPARATED BY SPACES, BY TAB CHARACTERS AND/OR BY
COMMAS. ^EXCESS COMMAS ARE IGNORED AND DO NOT INDICATE EITHER
MISSING OR ZERO VALUES. ^THE EVALUATION IS TERMINATED WHEN A
SEMICOLON IS FOUND WITHIN THE CONTENTS OF THE INPUT TEXT BUFFER OR
ELSE WHEN ALL OF THE CHARACTERS WITHIN THE INPUT TEXT BUFFER HAVE
BEEN INTERPRETED. ^AN EXCLAMATION POINT AND ANY CHARACTERS TO ITS
RIGHT ARE TAKEN TO FORM A COMMENT AND ARE OTHERWISE IGNORED. ^AN
AMPERSAND AND ANY CHARACTERS TO ITS RIGHT ARE SIMILARLY IGNORED, BUT
THE CALLING PROGRAM IS INFORMED THAT AN AMPERSAND WAS FOUND SO THAT
THE CALLING PROGRAM CAN READ NEW TEXT INTO THE INPUT BUFFER BEFORE
CALLING THIS ROUTINE AGAIN TO CONTINUE THE EVALUATION.
.SKIP
^THE REPRESENTATION OF A NUMBER CAN CONTAIN LEADING SIGN, EMBEDDED
DECIMAL POINT AND/OR TRAILING LETTER ^E WITH POSSIBLY SIGNED
EXPONENT. ^A PERCENT SIGN FOLLOWING THE NUMBER IMPLIES ^E-2,
TRAILING LETTER ^K IMPLIES ^E3 AND TRAILING LETTER ^M IMPLIES ^E6.
^TO BE RECOGNIZED AS PART OF A NUMBER, THE PERCENT SIGN OR LETTER ^K
OR ^M OR ^E MUST FOLLOW EITHER A SIGN OR A DIGIT OR A DECIMAL POINT,
OTHERWISE THE PERCENT SIGN OR LETTER ^K OR ^M OR ^E WILL BE AN
UNKNOWN CHARACTER.
.SKIP
^TWO VERSIONS OF THIS ROUTINE ARE SUPPLIED. ^THE LONGER VERSION,
NAMED ^^DARANK, \\REQUIRES THAT THE ROUTINES ^^DANEXT, DASPAN \\AND
^^DAHEFT \\BE LOADED TO ALLOW THE EVALUATION OF RANGES SPECIFIED IN
EITHER SLASH, COLON OR ASTERISK NOTATIONS. ^THE SHORTER VERSION,
NAMED ^^DAIRNK, \\TREATS THE SLASH, COLON AND ASTERISK CHARACTERS
THE SAME AS ANY OTHER UNKNOWN CHARACTERS, BUT ONLY REQUIRES THAT THE
ADDITIONAL ROUTINES ^^DAMISS \\AND ^^DAHEFT \\BE LOADED.
.SKIP
^THE RANGE SPECIFICATIONS ACCEPTED BY THE LONGER VERSION OF THIS
ROUTINE ARE WRITTEN AS A LOWER BOUND, INCREMENT AND UPPER BOUND
SEPARATED BY SLASHES OR BY COLONS (THE 2 CHARACTERS ARE EQUIVALENT).
^IF THE INCREMENT IS TO BE ONE, THEN THE LOWER AND UPPER BOUNDS NEED
BE SEPARATED ONLY BY A SINGLE SLASH OR BY A SINGLE COLON. ^IF EITHER
BOUND IS MISSING, IT IS ASSUMED TO BE ZERO. ^THE LOWER BOUND IS THE
FIRST NUMBER OF THE SERIES. ^THE SERIES CAN THEN EITHER INCREASE OR
DECREASE DEPENDING UPON WHETHER THE UPPER BOUND IS LESS THAN, EQUAL
TO, OR GREATER THAN THE LOWER BOUND. ^THE SIGN OF THE INCREMENT IS
CHANGED IF IT DOES NOT CONFORM TO THE RELATIVE VALUES OF THE BOUNDS.
^IF A RANGE IS SPECIFIED WHICH CONTAINS MORE VALUES THAN CAN BE
RETURNED TO THE CALLING PROGRAM, THEN THE PORTION OF THE RANGE WHICH
COULD CONTAIN ACCEPTABLE VALUES IS CALCULATED, SO THAT ALL VALUES
WITHIN THE ORIGINALLY SPECIFIED RANGE DO NOT HAVE TO BE INDIVIDUALLY
TESTED.
.SKIP
^THE LONGER VERSION OF THIS ROUTINE WILL ALSO ACCEPT A SINGLE VALUE
PRECEDED BY A NUMBER AND AN ASTERISK. ^THE ASTERISK NOTATION IS USED
BY OTHER ROUTINES IN ^^FASP \\TO INDICATE MULTIPLE APPEARANCES OF A
SINGLE VALUE, BUT THE INITIAL NUMBER IS IGNORED BY ^^DARANK \\OTHER
THAN TO DETERMINE THAT IT IS GREATER THAN ZERO. ^IF THE INITIAL
NUMBER IS NOT GREATER THAN ZERO, THEN THE VALUE FOLLOWING THE
SEPARATING ASTERISK IS NOT RETURNED TO THE CALLING PROGRAM.

^THE PROGRAM LISTED BELOW CONSTRUCTS A LARGE MULTI-PAGE BANNER WHICH
CAN BE PRINTED ON THE LINE-PRINTER. ^EACH BANNER CAN CONTAIN UP TO
10 PARALLEL LINES OF LETTERING. ^EACH LINE IN THE INPUT FILE SHOULD
CONTAIN THE HEIGHT MAGNIFICATION FACTOR, THE WIDTH MAGNIFICATION
FACTOR, THE INTERCHARACTER SPACING (BEFORE APPLICATION OF THE WIDTH
MAGNIFICATION FACTOR), AND THE NUMBER OF EXTRA BLANK LINES TO BE
INCLUDED IN THE BANNER PRIOR LETTERING FOR POSSIBLE CENTERING,
FOLLOWED ON THE SAME LINE BY A SINGLE CHARACTER WHICH IS IGNORED AND
THEN BY THE TEXT TO BE REPRESENTED AS A SINGLE LINE IN THE BANNER.
^THE NUMBERS ARE SPECIFIED AS INTEGERS. ^A LINE CONTAINING A SINGLE
ZERO TERMINATES THE DESCRIPTION OF A SINGLE BANNER. ^ADDITIONAL
GROUPS OF LINES CONTAINING NUMBERS AND TEXT CAN FOLLOW. TWO
CONSECUTIVE LINES EACH CONTAINING A SINGLE ZERO TERMINATE EXECUTION.
^THE CONTENTS OF A TYPICAL INPUT FILE DESCRIBING A FIRST BANNER
CONTAINING 3 LINES, AND A SECOND CONTAINING 2 LINES ARE SHOWN BELOW

T\\HE CHARACTERS PRODUCED BY THIS PROGRAM ARE TURNED 90 DEGREES FROM
THE ORIENTATION FOR WHICH THEY WERE DESIGNED. ^IF ^^TEXT5 \\IS USED,
THEN HEIGHT AND WIDTH MAGNIFICATION FACTORS OF 1 WILL GIVE LETTERS
WHICH ARE 9 COLUMNS HIGH AND 14 LINES WIDE. ^THE LETTERING CAN
EXTEND ACROSS THE FULL 132 COLUMN WIDTH OF THE LINE-PRINTER PAPER.
^TWO PARALLEL LINES OF LETTERING CAN BE GENERATED IF A HEIGHT
MAGNIFICATION FACTOR OF 5 AND WIDTH MAGNIFICATION FACTOR OF 2 ARE
USED. ^THREE PARALLEL LINES CAN BE GENERATED IF A HEIGHT FACTOR OF 3
AND WIDTH FACTOR OF 1 ARE USED. ^THE INTERCHARACTER SPACING SHOULD
BE ABOUT 2.

.SKIP
^THE ^^SUBROUTINE \\OR THE ^^BLOCK DATA \\ROUTINE WHICH DEFINES THE
CHARACTER SHAPES CONSTRUCTED BY ^^DATEXT \\IS ITSELF WRITTEN BY
ANOTHER PROGRAM NAMED ^^DAFONT \\WHICH READS A FILE WRITTEN BY THE
USER CONTAINING THE CHARACTERS DRAWN AS THEY WOULD BE CONSTRUCTED BY
^^DATEXT. DAFONT \\ASKS THE USER TO SPECIFY THE ^^SUBROUTINE \\NAME
WHICH IS TO BE INCLUDED IN THE ^^SUBROUTINE \\STATEMENT AND WILL
GENERATE A ^^BLOCK DATA \\ROUTINE INSTEAD IF NO NAME IS SUPPLIED.
.SKIP
^THE RULES GOVERNING THE CONSTRUCTION OF THE TEMPLATE FILE WHICH
^^DAFONT \\READS AS INPUT ARE AS FOLLOW.
.LEFT MARGIN 5
.SKIP
.INDENT -3
1.#^EACH CHARACTER SHAPE IS CONSTRUCTED ONLY OF THE CHARACTER WHICH
IT IS TO REPRESENT. ^SINCE ^^DATEXT \\CAN SELECT THE ^N'TH SHAPE BY
WHICH A PARTICULAR LETTER IS REPRESENTED, BOTH UPPER AND LOWER CASE
CHARACTERS CAN BE CONSTRUCTED IF IT IS NOT OBJECTIONABLE THAT THE
LOWER CASE SHAPES ARE CONSTRUCTED OF, AND SELECTED BY, THE
CORRESPONDING UPPER CASE CHARACTERS. ^THE ONLY PRECAUTION WHICH MUST
BE OBSERVED IF BOTH UPPER AND LOWER CASE SHAPES ARE TO BE AVAILABLE
BUT CONSTRUCTED OF THE UPPER CASE LETTERS IS THAT BOTH THE LOWER AND
UPPER CASE SHAPES FOR A PARTICULAR LETTER CANNOT BE DEFINED ON THE
SAME ROW OF SHAPES IN THE TEMPLATE FILE. ^ALSO, IF THE SECOND ROW OF
CHARACTER SHAPES IN THE TEMPLATE FILE DEFINES THE ALTERNATE CASE
SHAPE OF A CHARACTER IN THE FIRST ROW, THEN THE FIRST AND SECOND
ROWS OF CHARACTER SHAPES SHOULD BE SEPARATED BY ONE OR MORE BLANK
LINES. ^OF COURSE, IF THE ^^FORTRAN \\COMPILER AND RUNTIME SYSTEM
BOTH ALLOW LOWER CASE LETTERS, AND NEITHER TRANSLATES SUCH TO UPPER
CASE, THEN THE LOWER CASE LETTERS CAN BE SELECTED BY, AND BE FORMED,
OF THE LOWER CASE LETTERS BEING REPRESENTED.
.INDENT -3
2.#^THE FIRST ROW OF CHARACTER SHAPES IN THE TEMPLATE FILE BEGINS ON
THE NEXT NONBLANK LINE FOLLOWING THE FIRST LINE, AND EXTENDS TO
EITHER THE NEXT BLANK LINE IN THE FILE, OR TO THE NEXT LINE WHICH
CONTAINS NO CHARACTER ALREADY FOUND IN THE PREVIOUS LINES. ^THE
FIRST ROW OF CHARACTER SHAPE SPECIFICATIONS MUST BE OF MAXIMUM
HEIGHT. ^THE CONTENTS OF THE FIRST LINE OF THE INPUT FILE IS WRITTEN
DIRECTLY INTO THE OUTPUT AS A COMMENT LINE. ^THE LETTER ^C IS PLACED
AT THE START OF THIS OUTPUT LINE TO CAUSE IT TO BE IGNORED BY THE
^^FORTRAN \\COMPILER. ^IT IS SUGGESTED THAT THIS COMMENT LINE
CONTAIN A SHORT DESCRIPTION OF THE MATRIX UPON WHICH THE LETTERS ARE
DESIGNED.
.INDENT -3
3.#^SUBSEQUENT ROWS OF CHARACTER SHAPES START AT THE NEXT NONBLANK
LINE AND EXTEND THROUGH THE NUMBER OF LINES ESTABLISHED BY THE FIRST
ROW AS BEING THE CHARACTER SHAPE HEIGHT, OR EXTEND TO BUT DO NOT
INCLUDE THE NEXT LINE WHICH BEGINS THE SPECIFICATION OF THE SHAPE OF
A DIFFERENT CHARACTER OR CHARACTERS BUT WHICH DOES NOT CONTAIN ANY
OF THE CHARACTERS BEING DEFINED IN THE CURRENT ROW OF SHAPES. ^A ROW
OF CHARACTER SHAPES IS TOP JUSTIFIED IF THE ROW (AS OPPOSED TO THE
SHAPES WITHIN THE ROW) IS SHORTER THAN THE HEIGHT ESTABLISHED BY THE
FIRST ROW OF SHAPES.
.INDENT-3
4.#^CHARACTER SHAPES CAN CONTAIN HORIZONTAL ROWS AND VERTICAL
COLUMNS OF SPACES. ^CHARACTER SHAPES SPECIFIED ON THE SAME ROW CAN
BE SEPARATED BY SPACES OR CAN TOUCH, BUT CANNOT OVERLAP.
.INDENT -3
5.#^IF THE SHAPE OF A CHARACTER HAS ALREADY BEEN FOUND ON THE
CURRENT ROW OF CHARACTER SHAPE SPECIFICATIONS, THE NEW (RIGHT)
DEFINITION OF THE SHAPE IS IGNORED.
.INDENT -3
6.#^IF THE ^^FORTRAN \\SYSTEM DOES NOT ALLOW END-OF-FILE TESTS IN
^^READ \\STATEMENTS, THEN THE TEMPLATE FILE MUST BE TERMINATED BY
THE LETTERS ^^END \\ON A FINAL LINE NOT PART OF THE PRECEDING ROW OF
CHARACTER SHAPE SPECIFICATIONS.
.INDENT -3
7.#^UNLESS THE LIMITS AND DIMENSIONS IN THE ^^DAFONT \\PROGRAM ARE
CHANGED, ONLY THE FIRST 80 CHARACTERS ON A LINE ARE READ, A
CHARACTER SHAPE CAN BE NO MORE THAN 30 LINES HIGH, AND AT MOST 96
SHAPES CAN BE DEFINED.
.INDENT -3
8.#^THE MAXIMUM WIDTH OF ANY CHARACTER IS THE NUMBER OF BITS,
EXCLUDING THE SIGN BIT, IN A SINGLE COMPUTER WORD. ^THIS MEANS THAT
LETTER SHAPES UP TO 31 BITS WIDE CAN BE REPRESENTED ON AN ^^IBM 360
\\OR 370 COMPUTER.

^ON THE FOLLOWING PAGE IS SHOWN A SAMPLE TEMPLATE FILE. ^THE SHAPES
OF ONLY A FEW OF THE LETTERS ARE DEFINED IN THIS TEMPLATE FILE. ^AS
LONG AS THE CHARACTER SHAPES DO NOT OVERLAP, THE HORIZONTAL SPACING
BETWEEN SHAPES IS OPTIONAL. ^SIMILARLY, EXTRA BLANK LINES CAN
SEPARATE THE ROWS OF SHAPES. ^ON THE ^^PDP-10 \\COMPUTER, A BLANK
LINE MUST CONTAIN AT LEAST 1 SPACE TO BE RECOGNIZED BY A ^^FORTRAN
\\PROGRAM. ^THIS MEANS THAT THE BLANK LINE IN THE DEFINITION OF THE
SHAPE OF THE NUMBER SIGN CONTAINS AT LEAST ONE SPACE.
.SKIP
^IT SHOULD BE NOTED THAT IN THIS SAMPLE TEMPLATE FILE, A SECOND
SPECIFICATION OF THE SHAPE OF THE CHARACTER ^S ON THE SAME ROW OF
SHAPES AS THE FIRST HAS BEEN USED TO FORCE THE CORRECT VERTICAL
POSITION OF THE LOWER CASE SHAPES OF THE LETTERS ^S AND ^A. ^THE
SECOND SPECIFICATION OF THE LETTER ^S, IN THIS CASE A VERTICAL LINE,
IS IGNORED FOR OTHER THAN DETERMINATION OF THE FIRST LINE OF THE ROW
OF SHAPES. ^HOWEVER, IF THE VERTICAL LINE FORMED OF THE LETTER ^S
WAS NOT SEPARATED FROM THE FIRST SHAPE OF THE LETTER ^S BY THE SHAPE
OF SOME OTHER CHARACTER, THEN THE 2 PARTS WOULD HAVE BEEN TAKEN
TOGETHER AS THE SPECIFICATION OF THE SHAPE OF THE LETTER. ^THIS IS
NECESSARY IF CHARACTERS ARE TO BE ALLOWED TO BE FORMED FROM MORE
THAN 1 GROUP OF CHARACTERS, AND IS NECESSARY FOR SPECIFICATION OF
THE SHAPE OF THE CHARACTER _#.
.SKIP
^THE SAMPLE TEMPLATE FILE DEFINES THE LOWER CASE LETTER SHAPES G L I
S AND A, THE CHARACTER SHAPES : AND _#, AND THE UPPER CASE LETTER
SHAPES ^^S A I \\AND ^L. ^THE FIRST LINE CONTAINS A COMMENT TO BE
WRITTEN INTO THE OUTPUT FILE ON A LINE CONTAINING THE LETTER ^C IN
COLUMN 1. ^THE FINAL LINE CONTAINING THE WORD ^^END \\SIGNALS THE
END OF THE FILE AND IS OTHERWISE IGNORED.

^THE PROGRAM LISTED BELOW WAS USED TO GENERATE MOST OF THE FONT
ILLUSTRATIONS PRESENTED EARLIER IN THIS DOCUMENT. ^SINCE ALL OF THE
SHAPES FOR EACH CHARACTER MUST BE SHOWN, YET EACH LINE OF
CONSTRUCTED CHARACTER SHAPES CAN CONTAIN ONLY A SMALL PORTION OF THE
TOTAL AVAILABLE CHARACTER SHAPES, THE PROGRAM FIRST INSERTS A DOLLAR
SIGN AND CASE IDENTIFICATION DIGIT IN FRONT OF EACH CHARACTER SO
THAT EACH OF THE ALTERNATIVE SHAPES FOR ANY CHARACTER CAN BE
SELECTED INDEPENDENTLY. ^AN EXTRA DOLLAR SIGN IS ALSO INSERTED
BEFORE EACH DOLLAR SIGN FOR WHICH THE SHAPE IS DESCRIBED IN THE FONT
SO THAT ^^DATEXT \\DOES NOT INCORRECTLY INTERPRET THE ORIGINAL
DOLLAR SIGN AS THE START OF A COMMAND CHARACTER PAIR. ^ONCE A LINE
OF CHARACTER SHAPES HAS BEEN CONSTRUCTED, THE FOLLOWING DOLLAR
SIGN-DIGIT PAIR WILL HAVE BEEN PROCESSED, SO THE PROGRAM BACKS UP TO
THE PREVIOUS DOLLAR SIGN-DIGIT PAIR PRIOR TO CONSTRUCTING THE NEXT
LINE OF CHARACTER SHAPES. ^THE PROGRAM USES THE LARGEST
INTERCHARACTER SPACING WHICH WILL NOT REDUCE THE NUMBER OF CHARACTER
SHAPES INCLUDED ON THE LINE. ^A ZERO INTERCHARACTER SPACING IS
ALLOWED ONLY IF THE CHARACTERS ON THE LINE ARE EXTREMELY LARGE.

^PRIOR TO PASSING CONTROL TO ^^DAVARY, \\THE CALLING PROGRAM WILL
HAVE REQUESTED FROM THE USER A SPECIFICATION OF THE ARRAY LOCATIONS
WHICH THE USER WANTS TO EXAMINE AND/OR TO MODIFY. ^THE TEXT TYPED BY
THE USER IN RESPONSE TO THIS REQUEST IS EVALUATED BY THE ^^DAPICK
\\ROUTINE TO IDENTIFY THE ARRAY NAME AND ITS SUBSCRIPT RANGES, IF
ANY. ^^DAVARY \\IS CALLED SEPARATELY TO DISPLAY EACH OF THE VALUES
IN THE ARRAY LOCATIONS WITHIN THE RANGE OF ARRAY LOCATIONS INDICATED
BY THE USER. ^IF ^^DAPICK \\FOUND THAT THE USER TYPED AN EQUALS SIGN

PROGRAM SHOULD REQUEST THAT ^^DAVARY \\IS TO EVALUATE THE NUMBERS

LOCATIONS INDICATED BY THE USER, THEN, WHEN THE SUPPLY OF TYPED
VALUES HAS BEEN EXHAUSTED, ^^DAVARY \\WILL ASK THE USER TO SPECIFY
THE VALUE OF EACH OF THE REMAINING ARRAY LOCATIONS AS THE CALLING
PROGRAM STEPS THROUGH THE RANGE OF ARRAY LOCATIONS. ^WHEN THE USER
IS ASKED TO SPECIFY THE NEW VALUE, THE USER HAS THE OPTION OF
SPECIFYING NO VALUE IN WHICH CASE THE FORMER VALUE WILL BE RETAINED,
OF SPECIFYING A RANGE OF VALUES IN WHICH CASE ^^DAVARY \\WILL UPON
EACH SUCCESSIVE CALL SELECT VALUES FROM THE RANGE UNTIL THE RANGE IS
COMPLETED, OF SPECIFYING THAT SOME NUMBER OF ARRAY LOCATIONS ARE TO

IS TO RETAIN ITS FORMER VALUE. ^A COMMA WHICH IS THE RIGHTMOST
PRINTING CHARACTER IN THE BUFFER (EXCEPT POSSIBLY FOR SEMICOLONS

AMPERSAND AND ITS FOLLOWING COMMENT) INDICATES THAT THE ARRAY
LOCATION BEING ASSIGNED A VALUE WHEN THE INTERPRETATION OF THE

^NUMBERS, WHETHER USED TO SPECIFY SINGLE VALUES OR RANGES, CAN BE
TYPED BY THE USER IN EITHER FLOATING POINT FORM OR SCIENTIFIC
NOTATION. ^IF SCIENTIFIC NOTATION IS USED FOR THE SPECIFICATION OF
OCTAL NUMBERS, THEN THE EXPONENT TO THE RIGHT OF THE LETTER ^E
(WHICH MUST BE TYPED IN UPPER CASE) IS EVALUATED AS THE DECIMAL
NUMBER OF OCTAL DIGITS TO BE SHIFTED. ^IF AN INTEGER (EITHER OCTAL
OR DECIMAL) IS SPECIFIED WITH A DECIMAL POINT AND/OR WITH AN
EXPONENT, THEN THE VALUE IS FIRST OBTAINED AS THOUGH NEITHER THE
DECIMAL POINT NOR EXPONENT APPEARED, AND THIS VALUE IS SHIFTED ONLY
ONCE BY THE AMOUNT INDICATED BY THE COMBINATION OF DECIMAL POINT
LOCATION AND EXPONENT. ^IF THE NUMBER 1.2345^E3 IS TYPED BY THE USER
AND IS EVALUATED AS A DECIMAL INTEGER, THEN THE VALUE IS CALCULATED
TO BE 12345 BEFORE BEING DIVIDED BY 10 TO OBTAIN THE RETURNED VALUE
OF INTEGER 1234.

^A RANGE OF VALUES CAN BE SPECIFIED AS THE LIMITS BETWEEN WHICH AND
INCREMENT BY WHICH THE VALUE IS TO BE VARIED, OR CAN BE SPECIFIED AS
THE REPETITION OF A SINGLE VALUE. ^IF THE VALUE IS TO BE VARIED
BETWEEN LIMITS, THEN THE RANGE IS WRITTEN AS THE STARTING VALUE, THE
INCREMENT, AND THE ENDING VALUE SEPARATED BY SLASHES OR BY COLONS
(THE 2 CHARACTERS ARE EQUIVALENT). ^IF THE INCREMENT IS TO BE ONE,
THEN THE STARTING AND ENDING VALUES NEED BE SEPARATED ONLY BY A
SINGLE SLASH OR BY A SINGLE COLON. ^IF EITHER LIMIT IS MISSING, IT
IS ASSUMED TO HAVE THE VALUE ZERO. ^THE EFFECTIVE SIGN OF THE
INCREMENT IS CHANGED IF IT DOES NOT AGREE WITH THE RELATIVE VALUES

IN WHICH THE LEFTMOST PRINTING CHARACTER IS AN AMPERSAND, THEN THE
REMAINDER OF THE LINE IS SIMILARLY TAKEN AS A COMMENT, BUT THE USER
IS AGAIN ASKED TO SPECIFY THE VALUE. ^USE OF THE AMPERSAND AS THE

NUMBER FOLLOWING THE LETTER ^E OF THE EXPONENT IS EVALUATED IN
DECIMAL. ^IT MUST BE NOTED THAT NUMBERS EVALUATED AS NEGATIVE OCTAL
INTEGERS HAVE THE NEGATIVE OCTAL INTEGER AS THEIR VALUE, NOT AS

AN EXAMPLE, IF ^^KONTRL \\IS GREATER THAN OR EQUAL TO 4, THEN THE

^THE NUMERIC CODES BY WHICH CHARACTERS ARE STORED IN A COMPUTER ARE
