Hi Joe--

    Even before I started to run OS/2, I dropped MS assemblers and went
to Borland TASM when MASM 6.0 came out, due to the intentional
incompatibilities btween 6.0 and 5.1.

    IBM is distributing an updated beta of its new Assembly Language
Processor (ALP) in the Warp Toolkit with DevCon 10 (file date is
3-12-96); the README for the Toolkit advertises "Advanced compatibiiilty
with MASM 5.1" as a feature of the updated ALP beta.

    I tested ALP by assembling some old MASM 5.1 code for DOS, linking
it as a COM program and running it in a VDM.  Admittedly, this is not
much of a test, but it worked well enough for me to take TASM off my
system.  (I don't do much assembly language coding these days!)
