This is a record of changes to SAIL system.  An entry to this file
should be made whenever any changes are made to the system SAIL files
(SAIL.DMP, SAISGx.SEG, LIBSAx.REL, etc.) or after any modifications
to the SAIL source files (e.g., at the end of an editing session)
Reference should be made to the files BUGS & FEATS, as appropriate.

#TX#	fixed sources & patched sys:sail.dmp & saildd[s,ail].
	2-7-75 RHT

%##%	Recompiled @IT & put the result on system.  Left SAIL.OLD
	alone.  2-8-75 RHT

#TY#	fixed bug in source (LEPRUN) reported by LDE.  Made no
	changes to system files.  Bug may cause strngc lossages
	in programs involving string refitems.  If this happens,
	look here. 2-10-75 RHT

#TZ#	Typo in gen.  patched source & .dmp files
	2-12-75 RHT

%CA%	Added new routine CVASTR to STRSER sources.  Did not
	test, assemble, or update incremental manual
	2-12-75 RHT

%##%	Changed "=-" to a "-=" in TRIGS.  This was necessitated by
	a change in FAIL. Reassembled runtimes & put up new saisg8 &
	libsa8 on system.
	2-12-75 RHT

#UA#	Fixed a string gc bug in GOGOL.  Made a TENEX-only change
	to SAIL and CC[10x,ail] by putting a variable in the
	switched area that had been left outside in error.
	2-15-75  RLS

	Why is there a file HEAD.FAI on [S,AIL] in addition to HEAD?
	Do changes to HEAD have to be made to HEAD.FAI in addition?
	I changed a TENEX switch setting in HEAD, and then had
	to do the same to HEAD.FAI (which RPG favors over HEAD).
	2-16-75 RLS

	Above comment by RLS indicates a bug in SCISS, which is supposed
	to delete the file HEAD.FAI on the second pass. JFR

%##%	Edits to HEAD/7,17  SAIL/24  TOTAL/35  GEN/48  GEN/32,33
	to clear up BAIL recursive procedure type bits problem
	and define request protocol and residence of procedure
	descriptors for SAIL runtime routines and first pass at
	records and references.  New SAILDD. JFR 2-16-75

	Above changes also made to SYS:SAIL. JFR 2-17-75

%##%	Edits to TRIGS to take out the code JAM inserted therein without
	telling anyone.  Sent network mail to RICART%NCCT telling
	him what to do.  RHT 2-19-75

#UB#	An OLD and terrible bug (one of the "how did it ever work?" 
	variety in boolean code.  Made the appropriate patches in
	source & .dmp files RHT 2-21-75

%==%	Recd word from CMU that they have snarfed a copy of SAIL files
	& put up a system with no problems.  Send LDE a note thanking
	him for his nice compliments & warning him about #ub#.
	RHT 2-22-75

#%%#	One-word patch in BAIL code at BFORMS+24 [GEN/32], try to
	help recursive procedures and lexical nesting code. JFR 2-23-75

%##%	Snarfed copy of STATS from S,AIL to S,RHT & began making some
	changes for the sake of new-style records.  May be a bit bigger job
	than I thought, especially if Recuuo is to be flushed & string
	subfields are to be added.  Will continue working on in in odd moments.

#UC#	(CMU =E3=) two bugs in refitem deletion.  Patched LEPRUN & made new
	segment and SAILEP entry for LIBSA8.  RHT 2-26-75
