Been a while, and I don't remember the gory details of the syntax, but I believe there is a way to pass a stem to a function (and keep it local to the caller, the "expose" keyword comes to mind but I couldn't swear that's right). I do remember that there is no way to return a stem other than having used it in the parm list. -- TWZ
