I don't think so, because the problem is the keyword. But
using JD's Call_Function gets around this with the compiler
because the program isn't compiled (which is when the number
of keywords is "attached" to the program module) until run-time.

And, anyway, I consider the use of FORWARD_FUNCTION to
be an admission of a program structure that is out of
control. Nothing against it, you just wouldn't find it
in any of my programs. :-)

Cheers,

David

P.S. I don't think I have the energy for another long
thread. Let's just write it off as one of my personal
quirks. :-)
