***** Begin Version 6 *****

30	1107	TFV	10-Jul-81	------
	Prohibit 0H hollerith constants and '' character constants.
	New errors are E158 (IVH) for invalid hollerith constant 0H and
	E159 (IVC) for invalid character constant ''.

34	1126	AHM	22-Sep-81	Q20-01654
	Remove last vestige of CALL DEFINE FILE support.

36	1141	EGM	27-Oct-81	10-31686
	Produce fatal diagnostic when octal constant contains more than
	24 significant digits.

***** Begin Version 6A *****

1162	PY	29-Jun-82	------
	Call WRITECRLF to type a CRLF when control-Z is typed at
	a terminal.

***** Begin Version 7 *****

27	1214	CKS	20-May-81	------
	Add state to classifier for IF (...) THEN

28	1213	TFV	20-May-81	------
	Fix access to TYPTABle. Entries are now two words long. Second word is
	the character count for character data.  IDATTRIBUT(PARAMT) and IDCHLEN
	fields of symbol table entries are defined here and in FIRST.BLI.

29      1221   	CKS	4-Jun-81
	Fix literal string parser to store characters of the literal starting
	at LITC1 (byte ptr to first char of literal) instead of using hardwired
	constant of 3.  Unfortunately LEXICA cannot be compiled with FIRST, so
	we can't use LITC1 (or even structure BASE), so change the hardwired
	constant to LTLSIZ (copied from FIRST).  The definitions of LTLSIZ in
	FIRST and LEXICA must agree.

31	1244	CKS	31-Jul-81
	Add CONCAT lexeme (//).

32	1245	TFV	3-Aug-81	------
	Fix LITDEF and ENDOFLIT to handle both character and HOLLERITH data.

33	1247	CKS	6-Aug-81
	Modify classifier to recognize substring assignment statements.

35	1271	CKS	9-Oct-81
	Modify classifier to treat "DO 10 ," as a DO statement.

37	1465	CKS	14-Jan-82
	Add global state GSTKSCAN to scan "LETTERS=".  It's used to parse
	IO statement keyword lists in contexts where you can see either
	a keyword or an expression.  Also, LEXICA won't compile, so try
	to squeeze under the 2**15 punt limit by removing the ACTnnn symbol
	names.  It is no longer possible to automatically generate the 
	CASE statement.

1505	AHM	13-Mar-82
	Make state ACMENDID (end of identifier) set the psect index of
	the symbol  table  entry it  creates  to PSDATA  in  order  to
	relocate those references by .DATA.

1526	AHM	8-Apr-82
	Set IDPSCHARS to .DATA. as well for CHARACTER variables.

1527	CKS	29-Apr-82
	Remove edit 717.  Its purpose is to prevent the substitution of
	constants for parameter variables on the left hand side of a parameter
	definition.  It regognizes this case by checking the upcoming lexeme
	to see if it is "=".  This check is no longer possible when the right
	hand side is parsed as a general expression because LEXL and LSAVE are
	not always set up correctly.

1530	TFV	4-May-82
	Fix ACMENTLITLEX and ACMLITEDCHK.  The CORMAN calls for literals
	must request  at  least  FLSIZ words.   This  causes  CORMAN  to
	allocate memory at JOBFF and prevents SAVSPACE from reusing  the
	space.  Add binds for CHARSPERWORD (also defined in TABLES)  and
	FLSIZ (also defined in FIRST).

1551	AHM	3-Jun-82
	Change the  value used  for PSDATA  in ACMENDID  since it  was
	changed in FIRST.

1565	PLB	21-Jun-82
	Use OUTTYX macro from LEXAID for instead of OUTSTR
	as part of TOPS-20 nativization.

1573	CKS	1-Jul-82
	Change classifier to recognize DO statements without a statement
	label (of the form "DO I = 1,10").  Add classifier states to detect
	DO WHILE statement.

1633	TFV	1-Sep-82
	Count number of source lines for /STATISTICS

1640	RVM	7-Oct-82	Q10-00144
	Fix bug that caused the ISN of the line being compiled to be off
	when the line is the last line of an INCLUDE file or the "main"
	input file.  The last line in a file is marked with EOF, rather
	than EOS.  This prevented the lexical action ACMLEXFOS from setting
	the line number correctly, since ACMLEXFOS only reset the line
	number if the line ended with EOS.  This error caused error messages
	to contain the wrong line number and to appear late in the listing.

1653	CDM	21-Oct-82
	In INITLZSTMNT,  check /NOERROR  flag  before typing  queued  up
	error messages to TTY.

***** End V7 Development *****

2035	TFV	16-Feb-84
	Fix edit 1640.  A file missing the CRLF on the last line  causes
	an ICE.  LEXICA was not  setting LASTLINE properly when EOF  was
	detected.


***** Begin Version 10 *****

2222	RVM	29-Sep-83
	Keep LEXICA from setting the PSECT fields everytime it sees an
	identifier.

2225	TFV	4-Oct-83
	Fix lexical processing  of octal constants.   Count the  leading
	zeros.  Up to 12 digits is  OCTAL, 13 to 24 digits is  DOUBLOCT,
	more than 24 is an error.

2241	TFV	7-Dec-83
	Implement  FORTRAN-77  continuation  line  processing.    Blank,
	comment, debug, and remark lines  may appear between an  initial
	line and its continuation lines and between continuation  lines.
	Also rework  the lexical  debugging trace  facility to  generate
	symbolic output.  To  use this facility,  DRIVER, INOUT,  LEXICA
	and LEXSUP  must be  compiled  with DBUGIT=1  (this bind  is  in
	DBUGIT.REQ), Specifying the /BUGOUT  switch outputs the data  to
	the listing file.  See  LEXSUP for a  description of the  BUGOUT
	values.  Also change the classifier and lexeme scanner to detect
	END  statements  properly.   The  standard  says  that  a   line
	consisting of  END must  be the  end statement  for the  program
	unit.  Continuation is not allowed.  Finally, remove dead macros
	and aliases.

2260	AlB	4-Jan-84
	Addition of checks for the Compatibility Flagger.
	Macros:
		ACMAYBDOUB, ACMCHECKLET, ACMCOMNT,  ACMDEBUG,  ACMENTREMARK,
		ACMGETOPR,  ACMGOTOCT,   ACMHOLEND, ACMMULTST, ACMNOTDOUB,
		ACMOPCHK,   ACMSINGLEX

2273	AlB	20-Jan-84
	The rework of LEXICA for the comment lines disturbed the processing
	of the ACMENTREMARK macro. In the new form, that macro is called
	when a comment line is recognized, not just when the "!" is seen
	on a line.  This edit adds code to handle the various 'funny character
	in column 1' flagger warnings.
	Macro:
		ACMCOMNT	ACMENTREMARK

2327	RVM	23-Mar-84
	Use SETPSECTS to set the psect fields for new identifiers.

2370	MEM     6-JUN-84
	Keywords will now be stored in KEYBUFFER so STA1 can recognize keywords
	past the sixth character. KEYLENGTH will contain the number of
	characters in KEYBUFFER.

2412	TFV	1-Jul-84
	Split LEXICA into  two modules.   The classifier is  in the  new
	module LEXCLA.   The lexeme  scanner is  in LEXICA.   LEXCLA  is
	called  to  initialize  each  program  unit,  to  classify  each
	statement, to classify the consequent statement of a logical IF,
	and to do the standard end of program and missing end of program
	actions.

2420	TFV	9-Jul-84
	Compact the  split  LEXICA,  LEXCLA modules.   Remove  the  dead
	states and macros from each.   Redo the PLITS of smalstates  and
	bigstates.  Change the lexical tracing routines for debugging so
	they typeout the  correct names.  Also  fix flagger warnings  so
	that each gets printed once instead of twice.  Finally, fix  the
	line numbers for the warnings, they were wrong and could ICE the
	compiler.

2455	MEM	30-Aug-84
	Replace all occurrences of VAX with VMS.

2474	TFV	21-Sep-84,	AlB	30-Oct-84
	Fix continuation processing to handle unlimited numbers of blank
	and comment  lines between  continuation lines.   The lines  are
	recorded in  a linked  list  of four  word entries,  defined  in
	LEXAID.BLI.  If there are too many blank and comment lines,  the
	buffer will get an overflow.   When this happens, the buffer  is
	compacted using the information in the linked list.  The info is
	also used  to speed  up continuation  processing in  the  lexeme
	scan.

	Make SPURFF and SPURCR be global routines so that they can be used
	by LEXCLA.

2475	MEM	5-Nov-84
	Fix bug where "-n where n was a double precision constant was
	incorrectly negated as if it were single precision.

2477	AlB	13-Nov-84
	Fix ACMENTREMARK to correctly test for column 1, and to use the
	global ANSIPLIT for its error message prefix.

2500	AlB	14-Nov-84
	Change the list of entries for source lines from a linked list
	in dynamic memory to a fixed-length list in static memory.

2501	AlB	20-Nov-84
	Special handling of errors found in comment lines.  Since these
	errors can be detected while scanning unprinted comment lines, they
	cannot go through the normal error queueing process.

2505	AlB	28-Nov-84
	Fix some printing problems: Blank lines that were surrounded by
	comment lines were not being printed, and BACKLINE was printing
	extra stuff.

	The SAVLINE routine in LEXSUP became so trivial that the call to
	it was replaced by in-line code.

2506	AlB	30-Nov-84
	Under certain conditions, comment lines were not printed because
	LASTCODELINE had moved too far down the linked list.  Now when
	a continuation line is detected, we back up to the first unprinted
	line before printing out comments.

2514	AlB	24-Jan-85
	Patches for QARs 853012 and 853013.

	Source lines with spaces (not tab) in the label field were being
	treated as code lines, even if they had no code.  This tended to
	confuse the comment/continuation code.

	Continuation lines in source statements which do not start with tab
	were causing preceding comments not to be printed.  Created new
	routine CONTPRINT, which is what was the guts of ACMCONTDIG.  This
	routine is now called from ACMGOBAKNXT and ACMCONTDIG in both
	LEXICA and LEXCLA.

2526	AlB	27-Mar-85
	Macro ACMLT modified to correctly handle a look-ahead problem
	which was causing some continued lines to either be printed twice,
	or to be printed as a blank line.  This would also cause garbage
	in the listing if that line contained an error.

***** End V10 Development *****

2540	AlB	27-Jul-85
	When a program contains an extra period at the end of a statement
	line, the lexical scanner looks for a dotted operator.  Since it
	fails when it runs out of statement, it erroneously skips past the
	next statement.

	Macros ACMMISOPER and ACMMISOP1 were modified to recognize that if
	they are already at end of statement when the error occurs, then quit
	immediately instead of skipping to end of statement.

2545	CDM	26-Aug-85
	Detect too many digits on the end of STOP/PAUSE statements and
	stop saving them away.  Too many digits will write over memory
	that isn't allocated for the literal constant.

2560	MEM	11-Nov-85
	When a source line is continued onto several lines, CHARPOS must be
	set back to the beginning of the line. If CHARPOS is left pointing
	to the end of the line, then everything on that line will be ignored.	

2573	MEM	17-Mar-85
	When there are exactly 99-100 continuation lines, routine SKIPDL
	gives an extra error message. This error message should never be
	put out.

***** End Revision History *****

***** Begin Version 11 *****

4511	CDM	23-Aug-85
	Detect too many digits on the end of STOP/PAUSE statements and
	stop saving them away.  Too many digits will write over memory
	that isn't allocated for the literal constant.

4515	CDM	20-Sep-85
	Phase I for VMS long symbols.  Create routine ONEWPTR for Sixbit
	symbols.  For now, return what is passed it.  For phase II, return
	[1,,pointer to symbol].

4527	CDM	1-Jan-86
	VMS Long symbols phase II.  Convert all internal symbols from
	one word of Sixbit to [length,,pointer].  The lengths will be one
	(word) until a later edit, which will store and use long symbols.

4530	MEM	17-Feb-86
	Add long symbol support for long identifiers with "$" and "_".
	Replaced MAXNWD and MAXLENGTH with MAXSYMWORDS and MAXSYMCHARS
	which are defined in LEXAID.

4533	CDM	2-May-86
	Corrected output of truncated long symbol when past 31 characters
	for warning message.

4537	MEM	21-May-86
	Modify ACMSINGLEX to handle the underline lexeme.

!	NOW ONE CAN DEFINE THE ACTIONS AND STATES
!
!	THE INDIVIDUAL ACTIONS ARE DEFINED AS MACROS.  THEIR NAMES  MUST
!	APPEAR IN THE  PRECEEDING TABLE,  BOUND TO AN  ACTION (OR  CASE)
!	NUMBER. ALL  REFERENCES TO  ACTIONS ARE  MADE THROUGH  THE  NAME
!	"ACTxxxx", WHICH  IS BOUND  TO THE  ACTION NUMBER.   THE  ACTUAL
!	ACTION MACRO DEFINITION NAME  IS NEVER REFERENCED EXCEPT  DURING
!	THE DEFINITION OF THE "LEXICAL" CASE STATEMENT.
!
!	THE INDIVIDUAL  STATES ARE  DEFINED IN  TERMS OF  A NAME  AND  A
!	SERIES OF BINDS OF INPUT  CODE TO THE DESIRED ACTION  (ACTxxxx).
!	THE STATE NAME IS NOT ACTUALLY DEFINED UNTIL LATER IN THIS  CODE
!	AFTER THE ACTUAL  STATE TABLE PLITS  HAVE BEEN DEFINED,  HOWEVER
!	THE STATE NAMES MAY  STILL BE REFERENCED  IN THE ACTION  MACROS,
!	SINCE THEIR REFERENCE IS NOT UNTIL EVEN LATER.
!
!	IN ORDER TO DEFINE A STATE TABLES VALUES, ONE PRODUCES A  SERIES
!	OF BINDS, 11  FOR THE SMALL  STATES AND 32  FOR THE BIG  STATES.
!	THE FORMAT IS CHARACTER  CODE (SUCH AS  "ILL"), SUFFIXED BY  THE
!	INDEX OF  BIGSTATE OR  SMALSTATE  TO WHICH  THIS NAME  IS  BOUND
!	FOLLOWING THE STATE TABLE PLITS, FURTHER  SUFFIXED BY A B (  FOR
!	BIGSTATE ) OR S (FOR  SMALSTATE).  FOR EXAMPLE IF THE  STATENAME
!	"STxxxx" IS BOUND  TO BIGSTATE[5],  THEN THE  DEFINITION OF  THE
!	RESULTING ACTION OF  SOME CHARACTER  CODE INPUT  SUCH AS  "ILL",
!	WOULD BE OF THE FORM:
!		BIND ILL5B = ACTXXX;
!
!	ALL PROCESSING DONE BY  "LEXICA" IS DEFINED  IN THIS SECTION  IN
!	TERMS OF STATES AND ACTION MACROS.
!
!	ALL STATES WHICH ARE LEXICA ENTRY STATES, I.E.  SPECIFIED BY THE
!	CALLER UPON  CALLING, MUST  BE BIGSTATES.   ALL RETURNS  TO  THE
!	LEXICAL CALLER  MUST  CLASSIFY THE  NEXT  SIGNIFICANT  CHARACTER
!	IN TERMS OF BIG CODES BEFORE RETURNING.

!                  FORMAT STATEMENT LEXICAL ANALYZER
!----------------------------------------------------------------------
!
!	The lexical analyzer for  FORMATS returns constants, literals  (
!	"'" and holerith  ), and single  character lexemes.  The  actual
!	lexeme number for any given  lexeme is obtained from two  tables
!	in FORMAT.BLI.  For letters  the code comes from  FMTLET[.CHAR],
!	for the other single  letter lexemes the  code is obtained  from
!	the table FMTLEX[.CODE] (i.e. the lexical character code is  the
!	index).   The  constant  lexeme  number  is  FMTLEX[DIGIT],  the
!	literal lexeme code ( or holerith ) is FMTLEX[LITSGN].
