Hi Daniel -

You're absolutely right on the reductions.  I'm still at the stage of just
following my nose, and when it works moving on.

This map thing you offered is intriguing.  I think I understand the concept.
But my Help lists don't show "map" as a primitive.  I got my MWPro direct
from LCSI less than a year ago.  Is there a more recent version?   When I
copied your line into the Command Center and ran it, I got "I don't know how
to map."  Have you written a mapping procedure?  It shouldn't be too hard to
do.

Be sure to check out the feedback from Jacques Mathil.  He makes my whole
strategy totally moot!

Regards,
-Jeff
