Hi Philippe,

Well, i think the problem is: when you don't define a variable, she is local to the PRG that you create. If you define a variable as LOCAL, she is local to your procedure/function. That's different, of course!
Check out PRIVATE variables, also! These are public until you close the procedure that created her.
Say anything if you need!

Cheers, and "Au Revoir", :)
