Bob, I'd suspect that you are overflowing your return stack when you try to do
that.  If you are doing this fairly deeply into you program and your main
routine calls a bunch of things before getting to the menu, then this is
pretty likely your problem.  You need to figure out how to reset the return
stack before executing main. Even if this is not what is hurting you yet, you
will need to deal with the return stack problem eventually.

Another possiblity is that your main was not defined when you define the '
main execute and you are executing some other definition of main that is doing
something nasty.  Check your load order to find out if that is the case.  If
so, you will need to use a DEFERed word to resolve the forward reference for
you.

I assume this is F-PC, but I don't use it much.  Does it have some kind if
contol over ABORT?  Realistically, your main word is nothing more than another
version of QUIT (where ABORT usually goes to). Many systems give you a way to
change where ABORT goes to so that you can define alternative QUIT's.  Check
out how ABORT or ABORT" works and you will probably find a way that you can
use.
