Hi Ronald
VFP Exes get their "command arguments" only on enter (as parameters of the main procedure, or the init event on the startup form). So there's no such thing as "pass a new parameter while running"... unless you use DDE (yeah, the old "obsolet" protocol) setting your running app as "DDE server". If you wish to do so take a look at the DDExxxxx functions.

Maybe it would be better to implement a COM component in VFP7, and call it with CREATEOBJECT.. or communicate with messages (MSMQ or file based) between your VFP applications.

HTH and bye
Jose.
