More on Call or Bound Call

I appreciate all of the feedback from Joel, Jon, Scott, Joep, and David 
(hope I didn't forget anyone).  I have two goals in putting these types of 
posts on the discussion group.  One, as you may guess from the subject 
matter of my original post, is to gather useful information pertaining to 
performance advantages of RPG IV over RPG III.  Second, will be to find 
opcodes, bif's, etc., that provide added functionality over what my shop 
has now using RPG III.  However, I have to sell my boss on making a move 
towards RPG IV, and he will be a hard sell coming from the "If it ain't 
broke...," point of view.  Plus, I'm in a Catch 22 situation: How do I 
learn without writing new code vs. the mind set of not changing the status 
quo.  (I realize I'm flogging a dead horse here, and I'm getting away from 
the subject at hand).  So, I'm gathering ammunition and hopefully will 
choose my battles wisely.

Also, I take no offense with any criticism of my syntax.  After all, if 
other people (with you guys being the experts) don't see what you do, it 
never gets critiqued!
