That is exactly what we did. For those that are interested we even wrote
the COMMAND intrinsic stub in COBOL.

As for forward compatibilty, if a user can move from 4.0 to 5.5, a fairly
drastic change in file systems/operating systems, and this is the only
thing they found to complain about then they haven't dealt with enough of
the other operating systems that are around.

Keep up the good work.
