	( X=B##+<N=N+1>-2 ) to generate correct code. 
1154	MFB	5-Sep-80
	Fix phase errors in literals caused by finding Polish
	in universal files.

1155	MFB	10-Sep-79

	Fix bad code generated by Bshift of a relocatable.

1164	MFB	1-Nov-79
	Fix bad Polish generated by X=<<FOO##+2>B8+17>

1165	MFB	25-Jan-80	SPR 10-28821

	that is inside phased code.

1167	MFB	21-Feb-80
	Edit 1151 broke more than one lit in the last program
	of a PRGENDed file.

1170	MFB	7-Mar-80
	Reset EXTPNT in STMNT9 in case MACRO cleared it while

	address for .LINK psuedo-op.

1173	MFB	24-Mar-80
	Allow KS10 as argument to .DIRECTIVE pseudo-op.

1174	MFB	2-May-80
	Fix bug with external symbol becoming relocatable after
	specifying .NODDT for that symbol.

1175	MFB	5-Jun-80
	Make "E" errors only apply to line where error occured
	and not the next binary producing line as well.

1176	MFB	5-Jun-80
	Reset CTIBUF if TOPS20 version and only an input file
	was specified.  (fixes loop at end of pass 1).

1177	MFB	10-Jun-80	SPR 10-29621
	If in remark, do not change "}","|","{" to strange control char.

1200	MFB	16-Jul-80	SPR 10-29754
	Assemble statements like: "HRLI (HRRZ ,(15))" correctly.
	Broken by edit 1113.

1201	PY	4-Sep-80	SPR 10-29907
	Flag error when symbol is referenced as external in universal
	file but local in program.

1202	PY	30-Sep-80
	Change revision history, starting with version 53B. Add
	date of edit, author's initials, and 10- or 20- to SPR
	number. Also change history to lower case.

1203	PY	1-Oct-80	SPR 10-30018
	Remove edit 653, as it is possible to generate UNV files
	with synonyms that do not have VARF set.

1204	PY	2-Oct-80	SPR 10-29908, 10-30021
	Test for inter-PSECT references involving special pointers
	with additive fixups that will not go Polish. These consist
	of LEFT,,0 where LEFT is non-zero.

1205	PY	3-Oct-80	SPR 10-30043
	If processing the END statement, and the start address label
	has the same name as a macro, do not incorrectly set the 
	inter-PSECT reference bit. Broken by Edit 1155.

1206	PY	14-Oct-80	SPR 10-30104
	MCROBL message is printed instead of MCROQE error, prefix
	is printed as garbage.

1207	PY	16-Oct-80	SPR 10-30103
	Fix skewed listing when BYTE or SIXBIT psuedo-ops are used
	in Psected programs.

1210	PY	5-Nov-80	SPR 20-15019
	Do not clobber the size of an ARRAY during pass 1 if the array
	is being made INTERNAL.

1211	PY	4-Feb-81	SPR 10-30309
	Remove code which does not allow semicolons or CRLFs in some
	failing conditionals.

1212	PY	11-Feb-81	SPR 20-15625
	Fix handling of constants to give Q error in more cases
	of integer overflow. Also fix code so that floating point
	numbers will not get erroneous Q errors when the part before
	the decimal point is too large to fit in an integer.

1213	PY	17-Feb-81
	Fix edit 1204 so that special pointers with zero fixups will
	always be copied. The only fixup that should not be copied
	is one which has a non-zero right half. This is because it
	is legal to say SKIPE ABC where ABC is a special pointer with
	a zero addition and this case will not go Polish.

1214	PY	24-Mar-81	SPR 10-30814
	An incorrect feature test flag could allow KL symbols
	to be defined without KI symbols being defined.

1215	PY	27-Apr-81
	If a fullword expression containing an external is in
	angle brackets it will go polish on pass 2. Therefore,
	do not fold it if it is in a literal in pass 1.

1216	PY	1-Sep-81
	Make DEFINE A(B,,C) take a more severe error, so that
	the universal file writer will not be confused by a bad
	definition.

1217	EGM/PY	27-Jan-81	SPR 20-17083
	Change the way negation is done to fix cases such as
	<-.>  and negation of relocatables in general.

1220	EGM	3-Feb-82	10-31828
	Eliminate large number of causes of ?Ill mem refs for address 777777.
	Convert fake Polish relocations back to listing flags at proper points.

1221	EGM	3-Feb-82
	Flag cases of bad Polish fixup chains with E errors.

1222	EGM	3-Feb-82
	Add code to report pass 1 only Polish as a new type of undefined
	variable, which is declared as external at the end of pass 2.

1223	EGM	4-Feb-82
	Eliminate longstanding bogus E error for BYTE (18) EXT##.

1224	EGM	4-Feb-82
	Allow use of Variables/VAR with PSECTs. Broken by edit 602.

1225	EGM	4-Feb-82
	Prevent Polish data on temporary stack from being destroyed during
	complex expression evaluation.

1226	EGM	15-Feb-82
	Alter type 2 .REL block symbol codes for partially defined globals to
	eliminate confusion at LINK time. Right half deferred = 24 (same),
	left half deferred = 30 (new), both halves deferred = 34 (new).
	Also eliminate extra bit (04) in second symbol bits for 60/50, 60/70
	pairs, to conform to documentation. Requires LINK edit 1330.

1227	EGM	17-Feb-82
	Eliminate bad .REL files for left half Polish in OPDEFs and assignments
	that are not enclosed in angle brackets. Also correct edit 767 to catch
	relocatable left halves with Polish right halves.

1230	PY	16-Feb-82
	Allow expressions of the form A=B##,,0 in UNIVERSAL files.
	This edit supercedes edit 1201.

1231	EGM	18-Feb-82
	Eliminate spurious listing header to TTY:, and wrong elapsed times
	during PRGEND processing (edit 1141). Also cleanup edit 1146.

1232	PY	17-Jun-82
	Allow assignments or opdefs before .COMMON statements.

1233	PY	12-Jul-82
	Fix typo in edit 1222.

1234	EGM	28-Sep-82	SPR:10-32977
	Finish up job started by 1113/1147 treating OPDEFs at all levels
	in a consistent manner. Re-instate useful deviation from documented
	behavior that essentially causes entry into an angle-bracketed
	expression to revert to opcode field processing to allow
	processing Opcodes/OPDEFs as operators and not symbols.

1235	PY	30-Sep-82	SPR 20-18269
	Allow PSECT origins to be greater than 18 bits.

1236	PY	8-Dec-82	SPR 10-33238
	Add G-floating instructions, XMOVEI, and XHLLI.

1237	PY	26-Apr-83	SPR 10-33691
	Fix typo in edit 1236

1240	PY	10-May-83
	Fix external in END statement. Broken by edit 1234.

1241	PY	27-May-83	SPR 20-19194
	Dont increment count twice for psect indices when counting
	for long polish blocks.

1242	PY	3-Aug-83	SPR 20-19096
	Fix problem with CREFing psected programs. Don't use
	DEFCRS when updating a symbol, since the cref code turns
	it off.

1243	HD	22-Feb-85	SPR 10-35085
	IOWD constant,external will go polish on pass 2, therefore don't
	fold it in if it is in a litteral, during pass 1.

1244	HD	13-Nov-85	SPR 20-20963
	Flag LOC value greater than 18 bits as an error.

1245	HD	13-Jun-86
	New corporate copywrite notice.
