This may be a personal preference, but since reports are not truly OO, I put any UDFs that are called by reports in a separate proc file which I set prior to calling any report and release afterwards. If it's a function that you need while the form is active, you could issue a SET PROC in the load or init event and a RELE PROC in the the release or unload event.

Just my idea. HTH
