1.0##<SUMMARY
.B1
^The purpose of this release is to provide a more reliable version of
the product.
.B 1;.LM 0
<MACRO VERSION <53A IS SUPPORTED BY ^DIGITAL ^EQUIPMENT ^CORPORATION, AND
RUNS ON ALL SUPPORTED MONITORS AS RELEASED. ^VERSION <53A FULLY
SUPERSEDES ALL PREVIOUS VERSIONS, AND INCLUDES EDITS UP TO _#1152.
.B1
<MACRO <53A REQUIRES THAT IF <PSECTS ARE USED, THE RESULTANT <.REL FILES
BE LOADED WITH <LINK <V4 or later versions, WHICH SUPPORT THE <PSECT FACILITY.
.B1
^FOR <TOPS-10 SYSTEMS, <MACRO IS DOCUMENTED IN THE <DEC<SYSTEM-10
^USER'S ^GUIDE, AND IN THE <DEC<SYSTEM-10 <MACRO ^Assembler ^Reference ^Manual,
order number ^A^A-^C780^C-^T^B.
.B
^FOR <TOPS-20 SYSTEMS, <MACRO IS DOCUMENTED IN THE <TOPS-20 ^USER'S ^GUIDE,
AND IN THE <DECSYSTEM-20 <MACRO ^ASSEMBLER ^REFERENCE ^MANUAL, order number
^A^A-4159^C-^T^M.
.B 3;.LM 0
2.0##<EXTERNAL <CHANGES
.lm9.b1.i-4
1.##<BYTE pseudo-op:
.s
^Externals must be loaded into either fullword (36 bit) or halfword (18 bit)
bytes. ^Relocatables must be loaded into fullword or halfword bytes, with the
exception that a right half only relocatable can be loaded into a right
justified byte that is between 18 and 36 bits in length. ^Examples:
.s .lt
BYTE (18) REL1, REL2 (6) 3 (30) RHREL3
BYTE (10) 5 (26) RHREL4
.el .s
.i-4
2.##^Unary operators:
.s
^Unary operators now properly take precedence over all binary and shift
operators. ^This conflicts with the existing documentation. ^The hierarchy
is now as follows:
.s .lm 12 .i-3
a.)#^All unary operators (+, -, _^-, _^^D, _^^O, _^^B, _^^F, _^^L, ^E, ^K, ^M, ^G)
.br .i-3
b.)#^Shift operators (^B-shift, underscore-shift)
.br .i-3
c.)#^Logical binary operators (_!, _^_!, _&)
.br .i-3
d.)#^Multiplicative operators (*, /)
.br .i-3
e.)#^Additive operators (+, -)
.s .pg .lm 9 .i-4
3.##^Error message standard:
.s
^ON <TOPS-10 SYSTEMS,
<MACRO will now observe the setting of the message level bits during error
message typeout (reference monitor <GETTAB table <.GTWCH(35)).
.s .i-4
4.##^Macro call statements and <XALL
.s
<MACRO will now list the entire statement in which a macro call appears if
<XALL is in effect. ^This may cause the source line to be broken up in the
listing if multiple macro calls appear on the same line, and the called
macros have imbedded line terminators. ^Comments on macro calls imbedded
within conditionals will also be listed, with the comment appearing along
with the last line of the macro expansion, even if no code is generated
for that line.
.s .i-4
5.##<.IF/.IFN pseudo-ops
.s
^Contrary to what the documentation states, the <.IF and <.IFN pseudo-ops
were never intended to take angle-bracketed expressions as arguments. ^Instead,
they are intended to provide a powerful mechanism for querying symbol table
attributes, given a valid mnemonic consisting of up to six <RADIX50
characters. ^The newly defined attribute, <"NAME", can be used to determine
if the argument is a single <RADIX50 symbol name. ^Such a symbol may be
enclosed in angle brackets, nested to any depth. ^The use of angle-bracketed
expressions is allowed, and treated as decribed below, however their use
is not recommended.
.s
^Limited expression handling has been implemented to handle situations in
which angle-bracketed expressions are used as arguments. ^Such an argument
will return the combined (<IOR<ed) attributes of its components, except in
the case of relocation attributes, which are handled correctly only for a
symbol. ^In addition, an angle-bracketed expression will have the newly
defined attribute <"EXPRESSION", providing a means of defending against
angle-bracketed expressions passed as arguments to macro calls. ^Note that
all arguments that work outside angle brackets will work inside them.
.s .i-4
6.##^Psects and literals
.s
^Proper termination of literals within code bounded by <.PSECT/.ENDPS is
now enforced. ^Early termination of a literal which was started in the same
<PSECT but at a higher level (due to nesting), or the failure to terminate
a literal which was started in the current <PSECT will produce an ^L error,
and will generate the new <MCRLNI ^Literal nesting incorrect message.
.s .i-4
7.##^Suppressed symbols
.s
^Symbols declared as suppressed internal, but defined by externals or ^Polish
will now retain the suppressed attribute and will not be typed out by <DDT.
.s .i-4
8.##<PSECT attributes
.s
^Valid <PSECT attributes and their definitions are as follows:
.s .lm 24 .i-15
<CONCATENATED###^When loading multiple modules, all <PSECT blocks having the
same name will be concatenated at load time.
.s .i-15
<OVERLAID#######^When loading multiple modules, all <PSECT blocks having the
same name will be loaded starting at the same origin (each one will
'overlay' the previous one).
.s .i-15
<RWRITE#########^The <PSECT can be read and written (<TOPS-20 only).
.s .i-15
<RONLY##########^The <PSECT can only be read (<TOPS-20 only).
.s .i-15
<PALIGNED#######^When loading relocatable <PSECT<s (not yet supported),
the <PSECT origin will be started at a page boundary.
.lm 9 .s .i-4
9.##<PSECT<s and <PRGEND
.s
<PRGEND<s can now occur in a source file containing <PSECT<s.
.s .i-4
10.#^Assembler typeout for <PRGEND<ed programs
.s
^When <MACRO is executed via a <RUN command, and the listing device is not
the terminal, the informational messages (<BREAK, <CPU <TIME, <CORE <USED, etc...), will be typed out for each program module in a <PRGEND<ed source file.
^The particular program module will be identified by a line following the
error counts, indicating "<PROGRAM <XXXX", where <"XXXX" is the information
appearing on the <TITLE statement for the module. ^If no <TITLE is specified,
the default <TITLE, <".MAIN" will be typed. ^The program identification line
will no longer be output to the listing file, however, it will now appear
with the errors typed out when <MACRO is invoked via the <CCL entry point,
as done by the <COMPIL class commands under <TOPS-10.
.s .pg .lm 9 .i-4

.B1.LM9.I-4
1.##<MACRO CAN'T GENERATE ANY ^POLISH BLOCK WHICH WILL USE MORE THAN 17 WORDS.
.B1.I-4
2.##^You cannot forward reference a ^Polish symbol of other than the form:
<EXT_#_#+<k or <EXT_#_#-<k

3.##^A ^POLISH <OPDEF IS TREATED INTERNALLY AS A FULL WORD ASSIGNMENT.
^AS A RESULT, <AC AND ADDRESS MAY NOT BE USED WITH IT.
.B.LM0.F.J
.lm9.b1.i-4
4.##<MACRO<'S FLOATING POINT INPUT ROUTINES DO NOT AGREE WITH THOSE
OF OTHER COMPILERS, <FORTRAN IN PARTICULAR.
.B1.I-4
5.##<MACRO WILL NOT ASSEMBLE A LINE IN <TOPS-10 <PIP CORRECTLY. ^The following
represents edit 346 to the product:
.b
^At <DSPTAB + 12^L:
.B1.I6
<DISP###),0
.B1
^ADD ANGLE BRACKETS AROUND THE UN-PAIRED CLOSE parenthesis such as:
.B1.I6
<DISP###_<)>,0
.B1.I-4
6.##<MACRO WILL NOT ASSEMBLE 2 lines IN <RUNOFF CORRECTLY:
.b
^At <FRCEND + 4^L and <FIN2 + 13^L:
.B1.I6
<MSG$###<ARG1,ARG2,,....."
.B1
^Enclose the last macro argument in angle brackets, such as:
.B1.I6
<MSG$###<ARG1,ARG2,,_<.....">
.s
or include the statement <.DIRECTIVE#<NO#<MACMPD somewhere near the beginning
of the program.
.B1.I-4
7.##<MACRO CURRENTLY WILL NOT ALLOW POOLING OF LITERALS WHICH CONTAIN LABELS.
.B1.I-4
8.##^IF THE RIGHT HAND SIDE OF AN ASSIGNMENT STATEMENT IS AN EXPRESSION CONTAINING ^POLISH, ANGLE-BRACKETS MUST SURROUND THE EXPRESSION.
.B1.I-4
9.#^INCORRECT <CREF LISTINGS GENERATED WHEN:
.B1.I5
_.ZERO LOOP OF <IRP IS DONE.
.B1.I5
_.REFERENCES SUPPRESSED BY <XLIST INSIDE MACRO EXPANSION.
.B1.I-4
10.#^PHASE ERRORS WILL BE GENERATED BY <MACRO WHEN ASSEMBLING
THE DISTRIBUTED <TOPS-10 <MIC SOURCE. <MACRO ALLOWS MACRO CALLS TO OCCUR
IN THE OPERAND FIELD OF A SOURCE STATEMENT. ^THE SAMPLE PROGRAM
BELOW SHOWS THE SEQUENCE OF INSTRUCTIONS IN THE <MIC SOURCE
WHICH CAUSES THE PHASE ERRORS TO OCCUR.
.B1.NF.I5
^^SEARCH MACTEN

MACERR:
.I5
END\\
.B1.F.J
^AS SHOWN ABOVE, <MIC.MAC FORWARD-REFERENCES
<MACERR, A USER-DEFINED LABEL. ^HOWEVER, <MACERR ALSO HAPPENS
TO BE DEFINED IN <MACTEN AS A MACRO. ^SINCE <MIC SEARCHES
<MACTEN, AND SINCE MACRO CALLS ARE ALLOWED IN OPERAND FIELDS,
THE MACRO DEFINITION IS USED IN ASSEMBLING THE STATEMENT
"^^JRST MACERR\\" IN PASS ONE. ^THIS CAUSES PHASE ERRORS IN PASS
TWO WHEN THE CORRECT LABEL DEFINITION IS USED. ^PROBLEM MAY
BE FIXED BY CHANGING THE LABLE NAME <MACERR SO AS NOT TO CONFLICT
WITH THE MACRO NAME.
.B1.I-4
11.#^IN <TOPS-10 <SETSRC.MAC, <MACRO ENCOUNTERS A FORWARD REFERENCE OF A
SYMBOL NAME <JSYS, AND <MACRO ASSEMBLES IN <TOPS20 <JSYS
OPCODE INSTEAD OF USER LABEL ADDRESS. ^The following change represents
edit 47 to the product, which eliminates the problem.
.s
^In macro <CTAB, 6 lines down, the macro definition:
.s .i 6
<DEFINE###<CC#<(NAM,ADDR)_<ADDR>
.s
should be changed to:
.s .i 6
<DEFINE###<CC#<(NAM,ADDR)_<Z <ADDR>
.s
.s .i-4
12.#^Attempts to compile field image <BACKRS.MAC to rebuild <BACKUP will
produce <R errors. ^These errors occur on erroneous <BYTE statements
that attempt to modify the high order bit of an 18 bit relocatable quantity.
^This type of error was not detected by previous versions of <MACRO.
.s
^At <FRSDTM + 0^L:
.s .lt
FRSDTM: BYTE (1)0 (17)FRSDAT (18)L$DATE ;LABEL CREATION
BYTE (1)1 (17)FRSDSD (18)L$DSTR ;DESTROY DATE
BYTE (1)0 (17)FRSSDT (18)S$DATE ;SAVE SET DATE

.el
.s .i-4
13.#^The opcode field of an instruction must evaluate to an absolute quantity at
compile time. ^Note that no error is generated if this condition is not met,
to allow for <OPDEF<s which contain relocatables, or externals in the address
portion of the instruction.
.s .i-4
14.#^Polish is not allowed an index field (eg. <ADDR(POLISH) ). ^Also,
externals are not allowed in the index field if the expression evaluates
to other than a zero in the left half. ^This restriction is imposed because
there is no polish swap operator. ^Note that the expression ( "<OP <AC,POLISH(1B1)" )
falls into this class of problems, however, it is not currently flagged as an error.
.s .i-4
15.#^Error lines in macros under <SALL do not list. ^They can not be listed
since the original source line is not around when the macro call line is
finally listed.
.s .i-4
16.#^Long binary generating lines under <XALL list only partially.
.s .i-4
17.#^Lines in an <IRP will usually not be indeneted properly when <LALL is in
effect.
.s .i-4
18.#^Under <SALL, the following example involving <REPEAT does not list as
expected.
.s .lt
REPEAT 2,<MOVE
COUNT=0>
.el .s
^The <REPEAT is closed off before the last line is listed.
.s .i-4
19.#^A formfeed followed by another formfeed causes MACRO to skip a page header.
.s .i-4
20.#<CREF reference line numbers can be incorrect for variables seen in <XLIST<ed
code. ^In the following example, <A is <CREF<ed as being referenced on the
line following <LABEL.
.s .lt
A=1
DEFINE X,<XLIST
A
LIST>
LABEL: X
Z
.el .s .i-4
21.#<MACRO<'s command scanner is very archiac, and does not neccessarily
conform to the currently accepted method of file specification scanning, such
as that used by <SCAN. ^In particular, the command:
.s .lt
FIL E.REL=FILE.MAC
.el .s
is accepted without error, and <FILE.REL is created. ^Also, a single filespec
will cause the <TOPS-20 version of <MACRO to loop until it eventually runs out
of core.
.s .i-4
22.#^The <.DIRECTIVE <.NOBIN does not work properly with <PRGEND<ed files, since
the directive immediately closes the <.REL file.
.s .i-4
23.#<.DIRECTIVE<s <MACPRF and <.NOUUOS do not get cleared across a <PRGEND.
.s .i-4
24.#<MACRO is unable to <PEEK ahead across the end of macro args, the end of a
macro, the end of an <IRP, or the end of a <REPEAT. ^This means that constructs
such as "==", "=:", "::", and others cannot be recognized across these limits.
^This is related to not being able to continue a line across these boundaries.
.s .i-4
25.#^Either "<A=B_#_#" or "<A=EXP <B_#_#" should generate fullword ^Polish. ^At
present, the first case generates a right half external fixup, and the second
case generates bad listing output and an incorrect <.REL file.
.s .i-4
26.#^Polish used as the argument to a <B shift operator may generate a bad
<.REL file, depending upon whether or not angle brackets surround the entire
expression, such as:
.s .lt
<<POLISH>B7*4>
.el .s .i-4
27.#^Characters that are not specified to be in <MACRO'<s recognized character
set, such as vertical bar, will be converted to a strange up-arrow character,
if they are passed over as part of an unprocessed conditional.
.s .i-4
28.#^A macro which contains <SALL and <XLIST will cause an extra blank line to
appear in the listing file, because both <SALL and <XLIST attempt to finish off
the current output line before changing listing modes.
.s .i-4
29.#^An unary minus preceeding a relocatable expression such as:
.s .lt
-<RELOC+2>
.el .s
generates garbage ^Polish.
.s .i-4
30.#^A ^Polish assignment statement with an imbedded assignment statement, such as:
.s .lt
A=B##+<N=3>
.el .s
will not generate the proper ^Polish fixup block for symbol <A.
.s .i-4
31.#^Phase errors can occur in a <PSECT<ed program that has a symbol defined
as a ^Relocatable, and also as a <MACRO/OPDEF/SYNONYM. ^This occurs because of the
following:
.s .lm 12 .i-3
^A.#<MACRO maintains a seperate symbol table for each <PSECT. ^This is done
to keep <EXTERNAL fixup chains seperate, and also for ^Relocatables since they
may be referenced from another <PSECT.
.s .i-3
^B.#<MACRO expects the two definitions for the same symbol (^Relocatable and
<MACRO/OPDEF/SYNONYM) to appear together in the same symbol table. <MACRO
frequently makes decisions concerning the treatment of a symbol using the
knowledge that both symbol definitions exist.
.s .i-3
^C.#^In a <PSECT<ed program, the two symbol definitions may actually appear in
different <PSECT symbol tables. ^This can also occur differently during the
two passes, depending on <IF1 and <IF2 conditionals. ^Also, if the
<MACRO/OPDEF/SYNONYM
is defined in a <UNIVERSAL, the situation is complicated since such
definitions are usually entered into the symbol table for the ^Global <PSECT
when the symbol is referenced.
.s .lm 9
^Given the above, it is possible to reference the wrong definition of a symbol
during pass 2 of the assembly, generating a different amount of code than was
generated during pass 1, causing the phase errors.

1.0##<SUMMARY
.B1
^THE PURPOSE OF THIS RELEASE IS TO PROVIDE A SOFTWARE MULTIPLE-SEGMENTATION (<PSECT) FACILITY.
.B 1;.LM 0
<MACRO VERSION 53 IS SUPPORTED BY ^DIGITAL ^EQUIPMENT ^CORPORATION, AND
RUNS ON ALL SUPPORTED MONITORS AS RELEASED. ^VERSION 53 FULLY
SUPERSEDES ALL PREVIOUS VERSIONS, AND INCLUDES EDITS UP TO _#1020.
.B1
<MACRO ^V53 REQUIRES FIELD IMAGE <HELPER.REL TO BE ON <SYS: IN ORDER TO TYPE OUT THE
HELP FILE <MACRO.HLP, WHICH SHOULD BE PLACED ON <HLP: OR <REL:.
.b1
<MACRO ^V53 REQUIRES THAT IF <PSECTS ARE USED, THE RESULTANT <.REL FILES
BE LOADED WITH <LINK <V4, WHICH FULLY SUPPORTS THE <PSECT FACILITY.
.B1
<MACRO IS DOCUMENTED IN THE <DEC<SYSTEM-10 ^USER'S ^GUIDE, AND
IN THE <DEC<SYSTEM-10 <MACRO ^USER'S ^GUIDE.
.B 3;.LM 0
2.0##<EXTERNAL <CHANGES
.lm9.b1.i-4
1.##<.PSECT PSEUDO-OP:
.B1
^THE <.PSECT PSEUDO-OP DIRECTS <MACRO TO START OR CONTINUE PLACING CODE AND/OR
DATA INTO THE NAMED PROGRAM SECTION. ^SYNTAX:
.B1.I5
<_.PSECT NAME, ORIGIN
.B1
^WHERE "NAME" IS THE NAME OF THE PROGRAM SECTION; NAME MAY BE ANY CONSTRUCTION
WHICH WOULD BE VALID AS A SYMBOL BUT WILL NOT CONFLICT WITH A SYMBOL OR MACRO OF THE SAME NAME.
.B1
<MACRO WILL GENERATE A GLOBAL SYMBOL HAVING THE <PSECT NAME AND AT LOAD TIME THE SYMBOL
WILL TAKE ON THE <PSECT ORIGIN AS ITS VALUE.
.B1
^THE ORIGIN, IF SUPPLIED IN THE PROGRAM, TELLS <LINK WHERE THE <PSECT ORIGIN
SHOULD BE. ^IF NOT SUPPLIED THEN IT MUST BE SET BY THE /<SET:NAME:ORIGIN SWITCH
TO <LINK. ^IF BOTH ARE SUPPLIED, WHICHEVER OCCURS FIRST IS USED AND
CANNOT BE OVER-RIDDEN BY A LATER DECLARATION.
.PG.B1.I-4
2.##<.ENDPS PSEUDO OP:
.B1
^THE <.ENDPS PSEUDO-OP DIRECTS <MACRO TO STOP PLACING CODE AND/OR DATA INTO THE
CURRENT PROGRAM SECTION AND TO START PLACING IT IN THE PREVIOUS (MORE OUTER NESTED) PROGRAM SECTION. ^SYNTAX:
.B1.I5
<_.ENDPS [NAME]
.B1
^THE NAME FIELD IS OPTIONAL AND IF PRESENT WILL BE CHECKED AGAINST THE CURRENT
<_.PSECT NAME. ^IF THERE IS A DISAGREEMENT, A WARNING DIAGNOSTIC WILL BE ISSUED. ^THIS
CHECK CANNOT BE DONE FOR THE BLANK <.PSECT.
.B1.I-4
3.##"<PSECT" ^NESTING
.B1
_.<PSECT AND <.ENDPS ARE ESSENTIALLY BRACKETS WHICH SURROUND THE CODE AND/OR
DATA WHICH IS TO BE LOADED INTO THE NAMED PROGRAM SECTION. ^THESE BRACKETS MAY
BE NESTED TO A MAXIMUM DEPTH WHICH IS AN ASSEMBLY PARAMETER NORMALLY SET TO 16 DECIMAL WHEN THE
<MACRO ASSEMBLER IS ASSEMBLED. ^ANOTHER SUCH ASSEMBLY PARAMETER WITHIN <MACRO IS THE MAXIMUM
NUMBER OF DISTINCT <.PSECT NAMES WHICH MAY OCCUR WITHIN A SINGLE ASSEMBLY; IT IS NORMALLY SET TO 64 DECIMAL.
.B1.I-4
4.##^RESTRICTIONS
.B1.LM13.I-4
A.##<.PSECT AND <.ENDPS ARE NOT ALLOWED WITHIN A "<UNIVERSAL" FILE.
.B1.I-4
B.##^WHILE <MACRO ALLOWS A MACRO AND A SYMBOL TO HAVE THE SAME NAME, THIS CAN PRODUCE
UNPREDICTABLE RESULTS IF THE TWO ARE NOT IN THE SAME SYMBOL TABLE DURING AN
ASSEMBLY. ^THIS CAN HAPPEN IF ONE IS IN A UNIVERSAL SYMBOL TABLE AND THE OTHER IS NOT,
OR IF THE TWO APPEAR TO BE IN SEPARATE SEGMENTS. ^IT IS RECOMMENDED THAT SYMBOLS
AND MACROS OF THE SAME NAME NOT BE EMPLOYED. ^IF THEY ARE, <DEC RESERVES THE RIGHT TO CHANGE
THE IMPLEMENTATION OF THE <MACRO ASSEMBLER WITH RESPECT TO HOW THIS SITUATION IS TREATED.
.B1.I-4
C.##^IF UNIVERSAL FILES ARE SEARCHED WHILE ASSEMBLING A PROGRAM WITH MULTIPLE PROGRAM SECTIONS,
SYMBOLS WITHIN THE UNIVERSAL FILES WILL APPEAR TO BE IN THE BLANK PROGRAM
SECTION. ^THIS IS PARTICULARLY RELEVANT TO RELOCATABLE SYMBOLS.
.B1.I-4
D.##<.PSECT, <HISEG, AND <TWOSEG ARE ALL MUTUALLY EXCLUSIVE.
.B1.I-4
E.##^LITERALS CONTAINING INTER-<PSECT REFERENCES WILL NOT BE COLLAPSED, THEREFORE
IF THERE ARE TWO SUCH IDENTICAL LITERALS, TWO SEPARATE ENTRIES IN THE LITERAL
TABLE WILL BE MADE.
.B1.I-4
F.##<PRGEND IS ILLEGAL WITH <.PSECT AND <MACRO WILL TREAT IT LIKE <END AND THE REST OF THE FILE WILL BE TRUNCATED.

^THE DESCRIPTIONS OF THE BLOCK TYPES 24,23, AND 22 SUPERCEDE THE DESCRIPTIONS IN THE <LINK MANUAL.
.B1
<BLOCK 24##--#<MACRO GENERATES A SET OF BLOCK 24'S AT THE BEGINNING OF THE ^REL FILE FOR EACH <PSECT
IN THIS ASSEMBLY. ^A TYPE 24 CONTAINS THREE DATA WORDS#--#A <PSECT NAME IN <SIXBIT, ITS ATTRIBUTES (RIGHT HALF)
AND ITS INDEX (LEFT HALF), AND ITS ORIGIN. ^A BLOCK 24 ESTABLISHES A <PSECT AND ASSOCIATES IT WITH AN
INDEX NUMBER SO THAT BLOCK 22'S AND BLOCK
11'S THAT FOLLOW MAY REFERENCE <PSECT<S BY THE <PSECT INDEX NUMBER.
.B1
<BLOCK 22#--#^INTERSPERSED WITH THE TYPE 1 AND TYPE 2 CODES THERE ARE TYPE
22 CODES. ^A TYPE 22 DIRECTS THE LINKING LOADER TO PLACE SUBSEQUENT TYPE 1 AND TYPE 2 INFORMATION INTO THE NAMED
<_.PSECT.
^A TYPE 22 WILL ALSO PRECEDE THE TYPE 7 BLOCK IF ONE OCCURS AND OTHER
TYPE 22S HAVE BEEN EMITTED. ^A TYPE 22 CONTAINS ONLY ONE DATA WORD WHICH IS THE <PSECT INDEX.
.PG.B1
<BLOCK 23#--#^<MACRO GENERATES A SET OF BLOCK 23'S FOR
ALL THE <PSECT<S AT THE END. ^A TYPE 23 CONTAINS TWO DATA WORDS. ^THE FIRST IS A <.PSECT NAME IN <SIXBIT. ^THE SECOND CONTAINS
THE <.PSECT BREAK.
.B1
<BLOCK 11#--#^THERE IS AN ADDITIONAL TYPE OF ^POLISH FIXUP WHICH OCCURS FOR ASSEMBLIES
WITH MULTIPLE <.PSECT<S. ^WITH MULTIPLE <.PSECT<S, IT IS NECESSARY TO DISTINGUISH AMONG
THE <.PSECT<S WITHIN THE FIXUPS IN ORDER THAT RELOCATION WILL OCCUR PROPERLY.
^HALFWORD <PSECT INDEX OF THE FORM 400000+(N-1) INDICATES NEXT
RELOCATABLE ADDRESS IS TO BE RELOCATED WITH RESPECT TO THE <PSECT
WHICH IS NAMED BY THE N'TH TYPE 23 BLOCK. ^THE VERY FIRST <PSECT
INDEX IN BLOCK 11 DEFINES THE CURRENT <PSECT AND THE
RELOCATION COUNTER FOR THE STORE ADDRESS. ^ANY RELOCATABLE
OPERAND WITH A DIFFERENT RELOCATION COUNTER MUST BE PRECEDED
BY THE PROPER <PSECT INDEX.
.B1
<BLOCK 10#--#^FORWARD REFERENCES OF A TAG DEFINED IN A <LITERAL ARE CHAINED SIMILARLY TO
THAT OF AN EXTERNAL CHAIN. ^A BLOCK 10 IS GENERATED CONTAINING THE VALUE OF
THE TAG AND THE START OF THE CHAIN. ^A SEPARATE CHAIN IS GENERATED

^THE <MACRO SOURCE FILE AS DISTRIBUTED ASSEMBLES AND LOADS
INTO A SHARABLE SEGMENT. ^FOR THIS RELEASE, <MACRO.EXE IS BEING DISTRIBUTED.
^INSTALLATIONS WITHOUT <.EXE FILE SUPPORT MUST RELOAD TO GET
<MACRO.SHR.

^TO INSTALL <MACRO ^VERSION 53 ON YOUR SYSTEM, COPY THE FILE
<MACRO.EXE TO <SYS:.
.B1
^THE DISTRIBUTED VERSION OF <MACRO.CTL WAS USED TO FIRST BUILD
<MACRO USING FIELD IMAGE (<MACRO 52) <MACRO, AND THEN USE THIS
CREATED VERSION TO CREATE ITSELF. ^THE TWO VERSIONS OF <MACRO ^V53
WERE THEN CHECKED FOR INCONSISTANCIES. ^NONE WERE FOUND.
.B1
^CUSTOMERS WHO WISH TO REBUILD <MACRO AFTER INSTALLING ANY CHANGES
CAN USE <MACRO.CTL AS A GUIDE TO THE BUILDING PROCESS. ^IT IS
UNLIKELY, HOWEVER, THAT THE <.CTL FILE CAN BE EXECUTED WITHOUT MODIFICATION
ON MOST USER SYSTEMS. ^IN PARTICULAR, ATTENTION SHOULD BE GIVEN
TO <ERSATZ DEVICES, STRUCTURE NAMES, <PPN<S AND OTHER SUCH SYSTEM
