No argument - except Const is not a 100% guarantee - only if the data type/size is not an exact match.

That***s cheating John <grin> - I absolutely agree that it is
***fighting*** the language.

To me one of the most valuable points of using subprocs is that I should
be able to rely on the fact that only the receiver changes and not any
of the parms. If you can***t be sure of that then a subproc has the same
problems as a subroutine i.e. you have to go look at the code before you
can be sure what it does.

By the way - I was not commenting on Chris*** option (should have made
that clear) but I never received the original post so I commented on
what I saw.

If you need p then it has to be two separate operations - RPG cannot
combine an assignment with a condition as you can do in some other
languages.
