Hello all,

Does anybody know of a way to tell in advance
whether or not a specific field will be defined
before its mapping macro is invoked?

I have not been able to find a solution.

After a field has been defined (DS or DC) I can
of course use the D' attribute. But to my
knowledge, this will not work *before* the
field in question has been defined.

I need to take action before the field is
actually defined...

Thanks in advance for any suggestions.

Cheers,
Abe Kornelis.
