a. This is two problems.
   I. rewrite won't create a file unless it first already exists.
      This is expected behavior.  If you close the file using
		close(f,'SAVE');
      the file will remain.  This is in the documentation.  I know,
      I know; this is different from just about every other pascal
      in existence, but due to historical reasons, HP has been unwilling
      to change.
   II.if it does exist it doesn't erase the old contents.
      I've never seen this problem.  Could you send me (please email
      or Postal - I usually don't read this notes group) some what
      strings and a code sample?
	what /usr/lib/pascomp
	what /lib/libpc.a
	uname -a
b. I use pdb all the time on complex pascal code without problems.
   What version of pdb are you running?
c. if you use the $DEBUG$ compiler option, line numbers will be correctly
   reported.
