Oh dear oh dear oh dear!


Why oh why would you not want to use such nice opcodes as ITER and LEAVE? These are perfectly valid ways to repeat or exit a loop, and should not be tossed into the same bucket as GOTO. Lots of languages have similiar constructs: C, Java, Python and Ruby have "break" and "continue", Perl has "last" and "next" (just to name a few other commonly used languages). Heck, even many implementation of Pascal, that paragon of structured programming virtue, have "break" (or "exit") and "continue"!

I think the only people who object to ITER and LEAVE in RPG are those who try too hard to follow the "rules" of structured programming. Structured programming is fine, but it still shouldn't be allowed to get in the way of readable programs. (Just my humble opinion.)

Cheers! Hans
