>>>You are right. However, I'm of opinion that you are actually breaking a 'standard rule' here. You are at risk of changing the value of a variable in the calling program. The code should be something like:
>>>
>>>

lparameters tlEnabled, toObject
>>>
>>>local loObjectX    && you're already using loObject for another purpose
>>>
>>>if vartype( m.toObject ) <> "O"
>>>	loObjectX = this
>>>else
>>>	loObjectX = m.toObject
>>>endif

Dragan, I think you're mixing us up here. If SET UDFPARMS is set to VALUE and a variable holding an object reference is sent as a parameter in a normal way, then that variable cannot be changed in the called function/procedure/method. If the setting is REFERENCE, then the variable can be changed. I think your usage of 'passed by reference' obfuscates things here.
