RE: Trigger parameter prototypes

[Scott Mildenberger <Smildenber@xxxxxxxxxxxx>]

It appears to me that you are worried about passing more data than
necessary.  Remember that RPG passes parms by reference (by default) so if
you are passing the parm you are in essence just passing the pointer to it
behind the scenes.  There is no need to define the parm as being a pointer,
by default that is what is being passed anyway.  If the field in the called
program is defined larger than what has been passed then you have to be
careful not to use more than was passed (the length parm can be used here).
