I want to use the UserData field of the NewMenu struct to hold a pointer
to a function to be called when a particular item is selected.  I am a little
dense and/or the documentation on GTMENUITEM_GETUSERDATA() is a little scant.
Likely a little of both.  Could someone please provide an example of what the 
fuction call would look like?  

(*GTMENUITEM_GETUSERDATA(ItemAddress(Menu, (long)selection)))();
just doesn't seem to cut it with my compiler, and since cdecl doesn't
understand the cast in the GTMENUITEM_GETUSERDATA macro, I don't either.

Thanks for any help!
