SALL
;Edit
; 442 1980 JMS Separate SYMBOL, NUMBER, and ISETAB from the rest.
; This allowed the use of SYMBOL.DAT for plotting
; characters on the VERSATEC using standard calls to
; subroutine PLOT.
;
; 505 20-Oct-82 JMS Remove debugging HALT that limited X,Y to 11.0 inches.
;
; 506 20-Oct-82 JMS Implemented CR, LF, TAB, BS, SI, and SO characters.
;
; 512 29-Oct-82 JMS Implement subroutine SETSYM to replace ISETAB/MSETAB.
;
; 513 2-Nov-82 JMS Fix bug near ISETA6 introduced by edit 512
;
; 514 9-Nov-82 JMS Do not special case CR, LF for centered symbols.
;
; 517 12-Apr-83 JMS Change SYMBOL to handle FORTRAN-77 CHARACTER variables.
; CALL SYMBOL (X,Y,HEIGHT,CSTRNG,ANGLE)
;
; 526 15-Sep-83 JMS Make 2 versions of SETSYM. The one written in MACRO
; does not use FOROTS I/O and is suitable for ALGOL and
; PASCAL on TOPS-10. The one written in FORTRAN-77 is
; suitable for TOPS-20 (since FOROT7 won't allow PA1050).

TTL (<DNUMBER - Dummy module for NUMBER>,DUMMY)
;Calling sequence:
; CALL NUMBER (X, Y, HEIGHT, FNUMB, ANGLE, NDIG)
; CALL NUMBER (X, Y, HEIGHT, FNUMB, ANGLE, NDIG, IRAD)
;
; (X,Y) - The coordinate of the first char to be drawn
; HEIGHT - The height of the numbers in inches
; FNUMB - The number for output (floating point real number)
; ANGLE - The angle of rotation
; NDIG - The number of digits beyond the decimal point
; IRAD - (optional) The output radix, from 2 to 36.
;Convert REAL number in FNUMB to a string of digits in NUMTXT, set NUMDIG,
; and then "CALL SYMBOL (X,Y,HEIGHT,NUMTXT,ANGLE,NUMDIG)".
;For example:
; Z = 3.141592653
; CALL NUMBER(X,Y,0.2,Z,90.0,2)
;will draw '3.14' at 90 degrees.

; (X,Y) - The coordinate of the first character to be drawn.
; HEIGHT - The height of the characters in inches.
; CSTRNG - CHARACTER variable or expression.
; IARRAY - Integer array of Hollerith characters, or an integer number.
; ANGLE - The angle of rotation.
; NUMCHR - the number of characters to be plotted from IARRAY.
; If NUMCHR is zero, plot the single character whose ASCII code is in ICHAR.
; If NUMCHR is negative, plot a centered symbol whose number is in ICHAR.
; -2 will draw the symbol with a connecting line to the old position.
; -3 will not draw the connecting line.

SUBTTL Subroutine Descriptions -- SETSYM - Get data from SYMBOL.DAT
; This subroutine reads the SYMBOL table from either SYS:SYMBOL.DAT[1,4]
;or SYMBOL:SYMBOL.DAT[-], or returns information about the tables.
;NOTE: In order to use the negative tables, the user must define the
;logical device SYMBOL: via the ASSIGN or PATH commands to the Monitor.
;Calling sequence:
; CALL SETSYM(IFUNC,IARG,IANS) !The 3rd arg may be a REAL variable
; IFUNC = (input) Name of the function to perform. INTEGER or CHARACTER*5.
; IARG = (input) The argument of the function
; IANS = (output) Returned answer (not necessarily an integer)
; CALL SETSYM('TABLE',ITABLE,IERR)
; IFUNC = 'TABLE' - Change tables or return the value of the current one.
; ITABLE = The number of the table to be loaded into memory for SYMBOL.
; + = Positive values read from SYS:SYMBOL.DAT[1,4]
; - = Negative values read from SYMBOL:SYMBOL.DAT[-]
; 0 = Same as CALL SETSYM('NUMBER',0,IANS)
; IERR = The error flag . Returned as 0 if no errors, as -1 if errors.
; CALL SETSYM('NUMBER',0,IANS)
; IFUNC = 'NUMBE' - Read the current table number.
; IARG = Ignored.
; IANS = The table number. Positive if the table was read from
; SYS:SYMBOL.DAT[1,4], negative if from SYMBOL:SYMBOL.DAT[-].
; CALL SETSYM('NAME',IARG,CANS)
; IFUNC = 'NAME' - Return name corresponding with table number.
; IARG = Table number, zero means current table.
; CANS = The table name returned as CHARACTER*15.
; CALL SETSYM('WIDTH',LETTER,IWIDTH)
; IFUNC = 'WIDTH' - Read the width for the specified letter.
; LETTER = The ASCII code or CHARACTER*1 variable. "A"=65.
; IWIDTH = The width as compared to the height, a number from 0 to 1000.
