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

Frank,

I use leave and iter all the time, and I consider my programs very structured 
and easy to read.   Yes, at first glance, it seems as
if they are just goto's without tags, but, when used as directed they subtract 
complexity and improve readability.

If you have to introduce complexity or inhibit readability to conform to an 
arbitrary set of rules, you are defeating the purpose of
structured programming.

These opcodes are simply another tool in your tool box, and like any tool can 
be used effectively, as well as abused.
