RE: read on a do loop

Just another small example....

If you try to please the masses, it only causes mass confusion....

All in all as long as the code is easy to understand & performs
correctly (& efficiently) who cares??

Most of the things I've seen come through this list lately are
preferential debates, not really helpful!

For someone who came here with a basic need or question, they most
likely leave with a solution & a migraine!!

Basically in a nut shell, if we can solve the querant's issue that's
lovely.  If they understand WHAT the solution is even better.  If we
innundate them with 1,000's of "use this" or "use that" we are more
likely causing more issues than we're solving.  

DISCLAIMER:
This is not an attack on anyone nor should it be interpreted as such.
There are a lot of great minds at work here (I'm not including myself
here, I'm a proud mental midget...), but remember most folks can't
understand Einstein...nor could they debate with him on the Theory of
Relativity!!!

Rob,

It always bugs me when I see someone using a SELECT statement with one
WHEN clause when a perfectly good IF statement would work.  You're using
two statements (SELECT/WHEN) to do the work of one statement (IF).

When there is another option then I'd code a SELECT or ELSEIF.  Using IF
doesn't stop me from thinking about a third option.  I'll use ELSEIF if
the ELSEIF was on another variable:

If A = 'XYZ';
ElseIf B = 50;
EndIf;

I'll use SELECT if all the conditions are on the same set of variables
(a truth table):

Select;
When A = 'XYZ';
When A = 'QRS';
EndSl;

Paul
