Without messing with the UDFParams command, the following is true:

Passing by reference
do myprg with lvar1, lvar2 - always byref
myprg(@lvar1, @lvar1) - always byref

Passing by Value
do myprg with (lvar1), (lvar2) - always byval
myprg((lvar1), (lvar2)) - always byval

myprg(lvar1, lvar2) - depends on SET UDFPARAMS setting

HTH.
