Re: Benefits of Sub-procedures

[rob@xxxxxxxxx]

I think that what you are saying is that if it's so simplistic that you 
don't want to bother with PI's/PR's then you wouldn't want to bother with 
BEGSR's/EXSR's.  Interesting thought.

By the way, I compiled a very simple program with a subroutine in it just 
to see if it generated any messages like RNF#### - list of subroutines. 
Nothing.  Too bad, if there was I bet you could have CHGMSGD and kicked up 
the severity to a higher number.  And that would have stopped the 
compiler.  I bet that's a technique not published in "How to Win Friends 
and Influence People".      :-)

Re: Benefits of Sub-procedures






Hey, maybe have the precompiler search for BEGSR's and kill the compile? 

Rob, it's not that I'd never RETURN from within a subroutine.  It's just 
that I'd
never tolerate a one-statement subroutine.  Never.  Don't even go there.
