It means that in the main proc, myvar points at the same memory address (it's located in the same place in the memory) as the public myvar declared at level 1. This is the reason for which the myvar variable is released also at level 1. As I already said, the params passing mechanism is responsible and not the fact that params would not be private.

>You are somehow right and I would not advise to release params in a proc. Anyway, I don't see any reason to do it. If you passed a param, probably you need it. So, there is no reason to release it. And even if you need to release it, don't do it. There's also kinda bug here. If the param has exactly the same name as the variable passed to, the variable will be released at both levels. If the name is different, the variable is released only at proc level. But all this comes from the passing by reference (for procs) and not from the fact that params are not private.

Paul,
This discussion got so long. We all have to write programs to earn. If you are sure in your main program you didn't release a variable declared at a higher level than simply remove the line or rem it. CPU would appreciate it. JP Steffen was so right about how you declared Clipper guilty.
