   I've encountered my first really flaky behaviour in 
   LightSpeed Pascal after MANY months of very good
   service.

   I made a number of changes to a 700 line unit.  During
   recompilation I got an error message:

   "The code generator has detected error number 210."

   What is this?  It failed in the middle of a case statement
   that used a with statement.  Removing the "with" seemed
   to solve the *immediate* problem.    

   The code that gave error 210 was something like:

	case i of
	   AveSort:  ....
	   MinSort:
	      begin
	      ....
	      with SomeVariable^ do
		 begin
		 if Position[Loc] then...  
			 *** failed on line above.  Replacing
			 *** Loc with SomeVariable^.Loc and
			 *** removing the "with" statement
			 *** got past this section of code. 
		 end;		
	      end;
	   MaxSort:...
	   end;

  Next strange behaviour that I have *not* found a work-
  around for (this showed up at the same time as the above --
  ie: I have not has a successful run since the above appeared):

	for i:= 1 to 8 do
		begin
		...
	(1)	if Position[i] = 1 then ...
		   ...
		end;

  At line (1) I get a run-time error that i is out of bounds. 
  The Observe window shows i = 9!  What gives?  It is a very
  simple stretch of code that was not modified since the last
  time it ran successfully.  It involves no procedure or
  function calls.

  This procedure is printing values to a window that come out
  completely wrong.  The Observe window and LightsBug show the
  expected values (not the values it printed) when I inspect
  the variables.

  Environment:  This is on LSP v1.0 on a 128K-upgraded-to-512K
  Mac (I know, Stone Ages) with 2 400K drives.  The project
  consists of about a dozen units, totalling about 2000 lines of
  code. The application's heap is set at 96K. 

  If anyone has any clues on this one, I'd be more than happy
  to hear from you.

  Another question:  what is the most recent version of LSP
  that can run reasonably on my machine (512K, 2x400K drives)?
