I got spanked big time for writing code like that. I was going to take it out the I rememberd bullet 3 on "Real Programmers Don't Eat Quiche".
"Don't comment their code. If it was hard to write, it should be hard to understand and even harder to modify."

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?

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? :-)
