No, I haven't done that, but it sounds like a good idea.

A bug somewhere else in my code, you mean?  That's what I fear, too (although I
don't
understand how a bug somewhere else could be triggered here).  Changing the
command[]
array from a local to a global array seems to have solved my problem, but I
still have
the nagging fear that the problem was caused by a nasty bug somewhere else in my
program, and that this bug may have other unpleasant consequences.
