Hi Kengwen,

If you wish to pass a parameters to a form you can do it with DO FORM WITH parameter. You need to have a PARAMETERS statement in the INIT event of the receiving form.

To return a value from a form you can RETURN a value in the UNLOAD event of a form. The form returning a value needs to be MODAL.
