I've also slipped in a free-form statement into existing fixed form code.

I even go so far as to move the free for line to the right so it's not so
jarring to look at.

Yes, that's a very good observation. In fact, it's the converse of what
I sometimes do today with fixed-format ILE RPG programs that need a new
CHAIN. I slip in a free-form "chain (fl1:fld2) file;". Sometimes the
simplest solution is the best.

Good point Joe.

Of course one interesting approach that would provide a simple answer

in

this case (albeit a bit ugly) is simply to keep the fixed form *Entry

Plist!

Don't even need /Free /End-Free any more - just do it.

Linoma's tool box is intelligent enough to spot the problem and

leaves

those C specs in place.

Actually, I agree with your premise, but I completely understand

Mónica's point. Having converted many programs from RPG III to RPG IV

to

RPG free, this is one of the most troublesome of the issues. In a

large

program I may have hundreds of lines of code that access the fields in

an

externally described data structure passed as a parameter. Because of

how

free works, I cannot define that parameter as an unqualified data

structure

which means that now I have to qualify the field name in every one of

those

lines.

It's a very specific issue, and one that has a workaround. Two, in

fact, but one involves extra moves (especially problematic if you

forget

to

move the field back at the end) and the other involves based pointers,

a

concept not always well known by the folks who maintain the current

code

base. It's just one of those nagging little things that can be a

hiccup

when trying to modernize, especially when you're helping your

programmers

modernize their skills at the same time.

Why? In fact if you;'re going to just do the same old same old why

bother to change to free?

Surely the whole point of changing is to get to use better methods.

And the methods available in free-form are much better and more

flexible.

So why penalize yourself - it makes no sense.
