>A few lines about this discussion. It's not true that the code does nothing. It releases a variable that may be declared local or public elsewhere.

Params are PRIVATE in FoxPro. It means that if you RELEASE a parameter variable, this is released locally, regardless if the same variable exists on a higher level. So, it doesn't make any difference if this is the main ptogram or a called one.

BTW, Barbara solved the "mistery": the programmer came from Clipper and in Clipper params are LOCAL and not PRIVATE.

How can it be used? I don't see it. :(
