If you mean which cell changed to generate a calculate event, there is no
readily available way to determine that. You would have to store the old
values of the parameters and compare to the current values.

Hi,

These days I am obviously asking too twisted question, and here's another
one: Is it possible to retrieve information which is the changed parameter
that has caused the invocation of VBA based user-defined function?

I am more interested in a solution via API rather than application logic,
which seems to be quite complicated to created.

Thanks for your time,
Nacho
