Subject: SUMACC bugfix in lib/io.s, lib/mactrap.s
Cc: croft@SUMEX-AIM.ARPA, sumacc@sumex

As promised, SUMACC is a beta release, and here are the first bugfixes
to prove it.  If you have a bugfix in the future, please send it to
info-mac@sumex and "cc" sumacc@sumex; the latter will cause the message to be 
filed in <info-mac>sumacc.mail.  

The fixes sent out will be applied as "incremental" fixes to the original
tar distribution;  we plan to update the tar file only upon "final"
release.

The fix to mactrap.s below handles "ostype" or "restype" strings (4 byte
strings passed on the stack) that were not word aligned.  The fix to
io.s corrects a typo.

Thanks to Mike Schuster at CALTECH for writing a "fromhex" in C to check
this out.  I'll post Mike's program in a following message.
