Christof,

Yeah, and I did mis-speak here. The key is the word "allowed" and the fact that the application must be free threaded. The function, as you know, sets the mask on which a processes threads (plural) may run. If an application, such as a VFP app, is single threaded, it really has no ability to take advantage of multiple processors. Somthing like SQL Server, because it's free threaded can.
