RE: ILE RPG:Is the use of ITER & LEAVE Structured Programming?

I agree whole-heartedly with this. I can't count the number of times I
have been lost in 'structured' code because of the mixture of ELSE and
END statements. The LEAVESR tells me I am done with the subroutine and
there's no need to look at anything else.
