The "interrupt" keyword doesn't seem to be documented anywhere except in
the README file on the installation diskettes.  On every release of MSC
so far (from 3.0 on), there's been at least one feature not mentioned
*anywhere* in the printed document.  This is just the latest one.

It not only generates an IRET instead of a return, it saves all registers,
and if you have suitable parameter declarations, you can change the registers
that get restored to the caller.  The order of parameters is documented in
the README file (I think it's called README.DOC but I'm not positive -- it's
on the setup diskette, though).

hope this helps...
