[comp.sys.misc] Microsoft and/or Intel ".obj" format

crds@ncoast.UUCP (Glenn A. Emelko) (04/22/88)

I need technical information on the object code format used by Microsoft on
the IBM PC, which is linked by the "link.exe" program.  I have been told that
this follows something called the "intel object format", or may at least be
loosely based on same.  Any/all replies welcome, and I'm willing to summarize
fully all that I find here.  I can't seem to find any technical details
anywhere.

This information is to be found in the Programmer's Reference Manual published
by Microsoft. The format is very similar to the Intel format, but with
some extensions and variations. Microsoft are not very good about keeping the
spec up to date and so you may find that the information in the reference
manual itself is outdated by the latest versions of MS-DOS. The copy I have
deals with MS-DOS up to v3.2 (I think).
