RE: Suggested Technique

Hi Joel,
 
<snip>
Dow NOT done;

exfmt screen;
select;
 
    when F3;
      done = *on;
    when cond1;
       leave_mode = cond1stuff();
       done = *on;
    ...........

enddo;
//execute code that relies on leave_mode value
</snip>
 
Yep, I use this too. I think the bottom line is that there are many ways to
write effective, readable, maintainable code. The trick is to not limit
yourself to just one. I think not using LEAVE or ITER in many circumstances
is the right decision. In other circumstances, it might be better to use
LEAVE and ITER.
 
As a matter of personal preference, for screen loops I use DO *hival and
explicitly leave via the LEAVE op-code. I also think a programmer's coding
style changes, depending upon where s/he works, where s/he picked up the
language, etc... We will probably find that we all code in our local "RPG
dialect". For example, I started writing in RPG when I worked for Geac (JBA)
in their central development team, and the code written by some of us guys
was so similar you could only tell who wrote what by the comments (my
comments did, and still do, end with three periods "..."). [of course, we
ALWAYS mod-marked our code, but you get my point :-) ]
 
In a similar vein, I always use DOW for read loops - I can't stand DOU,
followed by that annoying IF! ;-)
 
Cheers
