I am currently converting a program from Lisa pascal to MPW pascal.
I have never used the Lisa pascal compiler and do not have the
manuals. Does anyone know what the {$I-/+} compiler option does
in Lisa pascal. As far as I can tell, this option is not used
(at least as $I) in MPW Pascal. The $I option in MPW Pascal includes
a separate source file. I have MPW pascal 2.0b1;
Below is a small segment of the code showing the use of the
$I option.
PROCEDURE writerec (var fd: cfile; var rec: gcrec; recnum: integer);
BEGIN
seek(fd, recnum);
fd^:= rec;
{$I-}
put(fd);
if (IORESULT<>0) or (eof(fd)) then
errmes ('CONTROL FILE WRITE ', recnum, IORESULT);
{$I+}
END;
Please reply to me directly. Thanks for your help.

Lisa Pascal's compiler produces intermediate code (a .i file) which is then processed by a code generator module to produce linkable object code. The options in question simply tell the code generator to either delete or not delete the .i file after it is finished. Therefore it seems that you should be able to ignore the $I+/- options with no problem. My source is the Lisa Pascal 3.0 Release Notes.
