 	Cannot have ASSIGNC as the first thing following a BEGIN --
 	get a "CANNOT BEGIN A STATEMENT LIKE THIS, PROBABLY A DECLARATION

 	decl or statement before the ASSIGNC.  See ASSIGN.SAI[CMU,AIL]

 I have found a bug in EXPR!TYPE.  the code (page 23 of GEN)
 is not recursive -- i.e., things that need to be saved are not
 stacked by only stored in locations.  consequently, when one has
 embedded called to EXPR!TYPE (as in macros that call it),
 bad things happen to the code.
 
 my fix, which seems to work, is to use a stack in the obvious
 way.  shall i put it in?  do you want to see it?  (probably a good
 idea.)

 Dear folks,
 	We notice there has been some activity putting in tenex stuff.
 Is there some place we could look (or someone who will tell us) what
 the state of the world is.  We have been beating on Sail very heavily,
 and are attempting very hard to stay up-to-date with bug fixes (since
 we seem to bump into them frequently).
 	I guess, we mostly want to know how stable the S,AIL world is
 and what, if any, changes will effect us non-tenex folks.
 		thanks,

 People,
 	We have a new IOSER that mostly reflects some CMU features
 that are within CMUSW -- it also has a couple of minor error msg
 improvements.  We would very appreciate if someone could bless this
 copy and make it be IOSER on S,AIL, so that we won't have to
 edit these changes in in the future.  The new version is
 IOSER[CMU,AIL].  We have labeled our changes with =b4=, all within
 the CMUs.  
 	Please see if this can happen before anymore changes are made
 to IOSER at your end.
 	Would appreciate a confirmation when all is well.
 		thanx,

 The following bug, ompiled at the AI project with the /H
 siwtch on , or compiled here at Xerox just normally (remember,
 /H is standard on TENEX SAIL), gives the "Virual origin ---
 horseshit message.  However, thee is no trouble with the
 virtual origin -- the code comiled is fine, etc.
 
 (I remember finding a bug relating to this section of things
 when I took SAIL to NIH -- this error message was printed
 out when it should not have been.  Is is possible that the
 edit was lost?? I peered vbriefly at the ARRAY code on S,AIL
 and couldn't remember enuf context to decide whether the fix
 was there, or lost....)
 
 Here is the code:
 
 00100	begin "classify"
 00200	  integer uttn,i,j,k,l,m,n,iword,iutt,fnum,flen,lnum,llen,ds,
 00300	          depth,obr,descthresh,pdtol,dist,iw,ld,br,lt,utts,i1,
 00350	          iclass,ndesc,fb,nt;
 00400	  integer array big[1:20860,1:4],cs[1:13820],classes[1:55],
 00500	          where[1:40],ns[1:100],ibest[1:10];
 00550	  real res1,res2;
 00600	  real array result[1:55],iresult[1:55],best[1:10];
 00700	  string word;

 Here are some more SAIL things:
 
 1. The export world complains about the description of FILEINFO,
 on page 43 of the manual.  It says it returns a 6-word block,
 and the list of things gives 7 items.  Furthermore, these are not
 correct in the export world (10/50 or TENEX).  Suggest a comment
 about what happens in wexport world.  For example:  "FILEINFO
 fills the array with the results of the last LOOKUP or ENTER;
 consult the 10/50 manual for the format of these entries."
 
 2. The following program (which comes from an example on page
 30 of the manual) does not work, i.e. gets a syntax error inside
 the second remember....
 
 ε00100	begin
 00200	integer number; context context1,context2;
 00300	remember number in context1;
 00400	remember context1 in context2;
 00500	end;
 00600	
 
 
 That"s it.

 THE .DMP WAS LOADED /Y/VSAILRS, WHICH I THINK GETS RAID, BUT

 I ABANDONED MY SPECIAL MAGTAPE WRITER.  INSTEAD, I WRITE TAPES
 IN STANDARD TENEX DUMPER FORMAT (THIS IS A FORMAT THAT EVERY

 READ SUCH TAPES ON ANY SYSTEM (INCLUDING, INCDENTALLY, A TENEX
 ONE).  HOWEVER, THIS IS NOT QUITE WHAT IS NEEDED FOR BOOTSTRAPPING,
 BECAUSE THE SITE WILL NOT HAVE SAIL WITH WHICH TO RUN THE

 Here are two SAIL bugs for you:
 1.  The compiler does not handle -5 mod 1  correctly (yes, Virginia, both
 	of those are constants).  It does a 'movsi 230007' as the
 	answer!! (Where it gets that number from, I don't care to
 	even guess).
 2.  CVO will not read the most negative number (12 7's) because the
 	IMUL gets overflow when the sign flips.  This
 	causes an overflow trap (when trigs running), and an error
 	message.  The cure (I think -- I fixed this a NIH years ago,
 	and I don't quite remember, so you probably want to think about
 	it a bit) is to put JFCL .+1 under the IMUL, so that the
 	overflow code leves well enough alone.
 
 Bob Smith's new SAIL is really great here.  Boy is it slick.
 So nice.  Productivity up 3% overnight.  Hope the merge goes smoothly
 . Let me know if I can help.
 
 Happy Spring!

 Have trivial fix for non-constant null-string bug, very non-trivial
 fix for the suspected (now confirmed) flaw in your copy-to-top
 fix (which is in general very nice, not really a kludge, and helps
 a lot in my ultimate fix -- the macro body formal search problem again,
 of course).  This time I really have the fix.  THe problem has always 
 been my saving multiple string pointers on the stack so GC
 would adjust all together.  Now I will just save counters,
 and let substring operator regenerate BPs at right time --
 will save but one string, and your PNAME fix will do the rest -- 
 I'll try to get that into a copy of SYM manana, perhaps try it out somehow.
 Saved one instruction.
 
 anyhow, talk to you tomorrow.

 CMU bug report.  =B1=  LDE  23-Feb-74.
 	Seems that itemvar arrays get allocated looking
 	like string arrays if they are declared as STRING ITEMVAR ARRAY
 	or STRING ARRAY ITEMVAR ARRAY.  See ITBUG.SAI[A700SA00] or [CMU,AIL].
 	Besides being wasteful of space (twice as long), the accesses to it
 are wrong for non-built in ones, etc.
