In the end this is not necessarily a feature of a language, at least how I
see it. If you look at it, the code is basically an IF statement with the
result being passed to a variable vs. being evaluated by the IF construct.
Is that a correct way to view it?

Yes it's used in other languages. Can even get more complicated than that
using switches.
Doesn't matter what the value of it is. It will get re-evaluated and set to
the new condition.

Hi Aaron,
My first thought was WAOOUWW! I must do that.
But then I realised that anyone else in our shop reading that would
not understand.
Instead of Short way, maybe you should call it the lazy way.
I also had a mental block at first with this :
/FREE
i += 1;
/END-FREE
Instead of
/FREE
i = i + 1;
/END-FREE
But now I do it all the time. I've never once thought that it might
irritate my colleagues. Is this kind of syntax custIsVld = (custNbr
0); used in other languages? What happens if custIsVld is already *on?

Objet : Re: Niftiest thing(s) you have done in RPG ILE or /FREE
I wonder if you changed the question to be more pointed towards
certain concepts if you would get more responses. For example, if
you asked "what are some cool things you can do in one line of code"
then I would think back to something I learned early on that some
programmers still don't know you can do:
Long way...
D custIsVld s n
D custNbr s 10 0
/free
if custNbr > 0;
custIsVld = *on;
else;
custIsVld = *off;
endif;
/end-free
Short way...
D custIsVld s n
D custNbr s 10 0
/free
custIsVld = (custNbr > 0);
/end-free
Every time I get involved with a project with another
developer/customer I learn a bunch of tidbits that make my code
better, compiling easier, or best practices better. The people on
this list could write a book on all those cool things, but its all
in how to ask the question.
Does the above qualify as at least a smaller nifty thing? :-)
