>>Good point. The procedure GetGlobal() does exist. But the value returned from GetGlobal(2) is .F. when the array which is used to get the value is not yet defined. And once the array is defined, then GetGlobal(2) returns the folder name. So, what I did with the Dragan's suggestion is as follows:

The problem (my problem) was that I was testing this function, GetGlobal(2) so much at the top of the application where the SET PROCEDURE was not yet declared. and the error code was that program GetGlobal.prg didn't exist. I should have checked after than I could do simpler approach.
