>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:

Array is defined / not yet defined.

Sorry, could not resist :)
