Bean-  when the SX enters a sub-routine with a parameter, is that parameter the actual data, or just a pointer to where to find the actual data?  I think that would be the answer to his question.  If the parameter only contains a pointer of where to find the data, then No, he can't. 

I believe what he is trying to say is that he has a sub-routine with x-amount of parameters.

When you have a sub-routine that has parameters,  In that sub-routine, you need to assign the parameters to variables in order to work with them.

I think that he is asking if you can work directly with the parameter name instead of assigning it to another variable.

I don't know exactly how this is of benefit (Unless he is really crunched for codespace)...But I think that may be the question.
