Louis,

First, we should know what cMy_function() is doing. Second, usually, functions return a value to the calling program, but here you are passing cMy_String by reference, not value, so cMyString will not change...ie the value of it. If you want to manipulate the VALUE of cMy_String, pass it by VALUE... cMy_String=cMy_Function(cMy_String) but give the function a place to store the value once it returns to the calling program. We really need more code to see what you are doing to give the appropriate advice. Remember, a procedure or function is both, depending on how they're called, and if you call it as a function, you must DO something with the result.

Hope this helps
Jon
