RE: New RPG programmers

[daparnin@xxxxxxxxxxxxxxxxxx]

RPG can look straightforward on the surface but remember the cycle!  Even
if you don't use it, even with ILE, even with /FREE, it's still there.  If
I were new to RPG one of the first questions I would have is just what the
heck is LR, why do all programs set it on, and what happens if I don't?  I
still come across an occasional legacy cycle program (naturally, with no
documentation).

I agree.  (I'm in agree mode today :).)  RPG is pretty easy and
straightforward.  If a person graduated with a cs degree or done other
programming before, learning RPG on his/her own should be a piece of cake.

I don't think there is a need for an RPG tutorial, and this is how my
thinking goes.  RPG isn't a difficult language.  It doesn't have the
interesting character set of APL, nor does it have the complex OO
techniques of Smalltalk.  It's very straightforward, even with the
concept of externalised I/O.  About the only thing a beginner really
needs help on (that is, something that isn't found in C, Java, or VB)
is external device files like display and printers.  Especially
subfiles and how the various indicators affect the output.
