RE: Leave / Iter (was: Suggested Technique)

["Bob Cozzi" <cozzi@xxxxxxxxx>]

What's the real difference from a maintenance perspective if I use:
 EXIT_MODE = QUIT

or if I use:
  LEAVE or LEAVESR

It just seems strange that someone would advocate (and I'm not say you Joel)
avoiding Leave/LeaveSR and then use *IN03 in their code illustrating the
point.

Well... You could code it something like:
exit_mode = STAY;
//STAY is a constant--others defined for different possible states
dow exit_mode = STAY;
   select;
      when *in03;
         exit_mode = QUIT;

      when cond_1;
         exit_mode = proc_cond_1(....);
      ................

    endsl;

enddo;

In an event loop it's very likely that there is more than one condition
that will end the loop. It may be cleaner to examine the state,
especially since you may need to know the state after the loop ends.

Using an indicator variable cannot be the best solution.  I'm not saying
leave/iter is the best, but your solution leads to code duplication.
And we all know what code duplication leads to in the long run, from
both theoretical and practical perspectives.  :-(
