This is superbly brilliant!

Being a programmer, I immediately fell for the INTRINSIC approach.  One
problem is that the intrinsic in question (has anyone figured it out yet?)
is "relatively" new and may not be available on older versions of Classic
MPE.  So, I cannot just call the intrinsic: I have to try a dynamic loading.

I had began a little research project to find out how far back such
intrinsic is supported by MPE.  Mark's disarmingly simple
COMMAND-INTERPRETER approach bypasses such pains.  I can certainly issue
the command (from CM or NM) and, if it fails, it is just tough luck and the
ACDs don't get copied.  No big deal.

This is the kind of solutions I like!  The KISS ("Keep It Simple, Stupid")
philosophy.  It's so difficult for us "tecchies" not to get carried away by
technology!

I don't see how I could create the new file any other way.  Do you?
