Re: New to RPG

Wow, this has been great. Thanks everybody! I didn't intend to start a
"holy war" here. My supervisor has indicated that I know enough about the
cycle to hold my own at work. I've been going to a lot of these sites
everybody is recommending and they are just what I've been looking for.

A decent SQL based query tool would be a better choice IMO than the RPG

I agree with James Lampert. Do not ignore the cycle. I agree that in
"most" current applications, it is not utilized. However, when producing
reports or PDFs with subtotals, the cycle can't be beat. You do not have

to

worry about coding logic that says "compare these two values, and when

they

change, do that" for each subtotal level desired. It is much easier to

use

the cycle and only code what should happen when the value changes. Let

the

compiler worry about all of that extra comparison and save prior value
stuff so you don't have to. You can use the cycle in modern ILE-RPG code
also.

I had worked in a school system and people were always asking for

detailed

student reports with summarized data at the classroom [L1], grade level
[L2], school building [L3], and entire district level [LR]. That is

where I

learned an appreciation for the ease of Level Indicators and the Cycle.

In addition, if you have to maintain older code, you may need an
understanding of what the cycle does for you "behind-the-scenes".
