Re: Good places to use "The Cycle" in today's RPG was->Re: FW: Niftiest thing(s) you have done in RPG ILE or /FREE

I am amazed at the number of people who say that ITER and LEAVE are good
op-codes, but GOTO is a nasty op-code! 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!

The reason is that iter and leave work within structure. they always
go to the normal beginning or end of the structure. A do or a for
loop. It's always the inner most of those structures, and it's
ALWAYS predictable how they will work.

a goto (or cab), on the other hand, can jump right from the middle of
one structure, right into the middle of another structure. for
instance, start somewhere in the middle of a do loop, an if/else
structure, etc.
