Passing large parameters by value isn't something that the iSeries is
optimized for.  (I think this probably applies to any system.)

If you have procedures dealing with strings, defining the parameters as
CONST VARYING will probably get you the best performance.  If your
procedure has to make a local copy, it will only have to copy the
current length.
