What do you think ITER and LEAVE are, except a fancy GOTO without an explicit TAG? I felt the same way about CABxx (Case and Branch) when that was the popular new op-code!

I've seen this "GOTO by another name" argument a few times in this thread. Doesn't it logically follow then that loops and other branch statements (SELECT-WHEN, IF) are also bad?

FWIW, I also dislike CABxx, but that has more to do with my preference for subprocedures over subroutines. I also try to avoid ITER and LEAVE where possible, but I think that they can make code more readable in the "loop completion is the exception" cases that James mentioned. In those cases I find that putting all the logic in the loop's logical expression tends to make the expression overly complex.
