You would! :-) Actually, it's merely a personal preference. If you guys are comfortable with it, good for you. I'm not, good for me.


>Anyway, as to the continued raging debate about DO WHILE versus FOR..ENDFOR, you have to either force an EXIT or change the logical condition to get out of a DO WHILE, right? So, actually, FOR..ENDFOR is a different animal altogether because it acts upon the conditions of the loop itself, incrementally.

You've pretty much touched on my point. FOR...ENDFOR for a fixed number of iterations. DO WHILE if it's conditional. (I still want a true post-test iteration structure.)
