A bit of explanation may help. By default, parameters are passed by reference when making a procedure call:

DO MyProc WITH Var1, Var2
DO MyForm WITH Var3, Var4

and by value when making a function call:

? MyProc(Var1, Var2)

If you want to pass parameters by reference to a procedure call, use parenthesis

DO MyProc WITH (Var1), (Var2)

or with the @ symbol for functions

? MyProc(@Var1, @Var2)

You can switch the defaults globally with SET UDFPARM.
