The dartmouth Xcmd stack (v3.1) has an ObjectExists XFCN that can tell
whether an object of a type known to HC exists (card, button, field, stack)
This is a much needed function if you are going to do repetitive things
on cards of different shapes.  The stack is in the sumex archives for
ftp access.
