The behavior you describe is well-known and is noted in the dox for
MARK/RELEASE.  However, my understanding was that, at least since
version 2.5 (Current release is at least 2.9), it would go ahead and
free the memory anyway, with a msg to the effect that this may not be
exactly kosher.

In any case, you can get around the general batch file weirdness w.r.t.
freeing memory by using the FAKEY utility to generate keystrokes s.t.
the actual releasing is done at DOS command level rather than from the
batch file.  'least this is what I do...

BTW, there is another utility, called RELEASE.COM, which simply
generates a .COM file which, when run, will restore the memory
environment to whatever it was when RELEASE itself was run.  This one I
know works in conjunction w/batch files, although some definite
weirdness can be observed in that case.  Again, I recommend the use of
FAKEY to eliminate the weirdness.
