I would like to write a user defined function that, as part of its
execution, needs to know the cell address from which it is currently called.
I.e. if
cell A1
= UDF(parm1, parm2)
then,
what type of statement can I use in the UDF to return the executing cell
address "A1"?

Assuming, of course, that such a thing is possible. Thanks in advance.
Larry.
