Just to make sure I'm clear on this...

An app builds a list of FNs inside it's self using address& = @FN FNname

The app then calls a DCOD. The DCOD is in an external rsrc file.

The DCOD wants to use a FN in the callling app so it does a
DEF FN FNname(a, b, c) USING address&

then the DCOD calls the FN it wants with:

FN FNname(a, b, c)


so Rick, is this about right ??
