G'day,

	I am in the middle of writing a couple of test programs using DJGPP(a
dam fine compiler I might add) and was wondering if there was any way of
having a post portem debugging environment. I'm talking about something
like what the old modula-2 compilers used to have, where if an
unexpected crash occured, the compiled program would write out a dump
file which could later be analized with a debug version of the code.

	I was reading thru the notes that came with Quake, (since id used DJGPP
to write it I was looking for clues). I found mention of the that the
bug reports required the eight-digit number which comes after the eip=.
I take it that this comes from Charles Sandman's DPMI.

	Of what value is the 'eip=' number and is this a pointer or clue as to
what could have gone wrong in the program?? Is there any other method of
debugging a DJGPP executable after the fact??


	Any help you could give me would be appreciated.

        Thanks,

	   Martin.....
