First suggestion looks workable, altho it makes the called PRG a little awkward to work with ... instead of returning a result, it simply must modify one its parameters, correct?

Second suggestion won't fly, because i can't guarantee uniqueness.

>>How do I call a PRG that I know lives in a particular folder (which most likely is not in my search path) and return a result? Note that I have the full path to the PRG, and the path may contain spaces:
>>
>>lcPRG = "C:\Some Folder Name\SomePRG.PRG'
>>
>>lcResult = ??????
