Subject: How to preserve vector 7B while go32 is running?

ok, I figured out how to save and restore dos vectors in go32 on
entry/exit.  But what I really need is a way to keep go32 from using
vector 7B.  I would like to be able to shell out of demacs and have
the tsr's which use 7B to still be functional.  Also it would be nice to
be able to write an interface to these tsr's in djgpp.  It is not
obvious to me how go32 uses/trashes vector 7B from the source.  Can go32
be patched so as not to use/trash 7B?  Thanks for any info.
