Re: Style choices

While I don't use the cycle every day (Lx level breaks), I loved it when I
used it. It did a lot of the grunt work magically for me. :)

I still think of it as a fond friend who's there if I need (but probably
won't, and refuse to talk smack about it...haha).

"Magic" can be in the eye of the beholder.

i += 1
ordersExist = (numberOfOrders > 0)

Even though simple, these are expressions that RPG programmers aren't very
used to unless they've trained in other languages. They could be
considered magic from a certain point of view.

I agree with Peter. The level breaks especially. Not using a feature
because no other language has it just doesn't make sense to me.

Hi Roger,

Sorry, but "Despise" seems pretty harsh. "magic" code? Are all your

files

USROPN? Do you feel the need to explicitly open and close every file?

Do

you always put in "return" at the end of every procedure even if it

doesn't

return a value? If you know what something does, is it still magic?

I dislike coding level breaks when RPG will handle all that for me. I

know

what it does and when it does it. I effectively told it to do it when I
defined the level breaks the the L1-9 indicators. I know what the *inzsr
subroutine does when I use it -- by using it, I told it to do that. No
magic here.

My opinion of course.

I'll use subroutines for a quick & dirty little task - depending on the
usage - but it's pretty rare.

99% of the time, I'll use procedures. Local variables alone are worth
it. Return values are..... invaluable.

As to *INZSR.... I have NEVER used it. I despise "magic" code. Something
that just happens without me telling it to? No way.

I always have an Init() procedure or subroutine instead of *INZSR.

Sometimes I befuddle myself. This is one of those times.

It was suggested to me that we should be using PR & PI instead of
subroutines. Is that a good suggestion? Does that include *INZSR too?
