Re: Would it be a reasonable to ask IBM's programmers to write a %sortsfl(sfl: column)

Well, this is why I asked the question. If an ordinary RPG programmer
can do the sfl sorting himself, how hard can it be for the real experts
to do it inside the product?

As to the green screen being dead...yeah. It just takes me a long time
to accept the death of a friend. (for instance, I finally threw away my
OS/2 Warp package a year or so ago.)

I agree 100% with Scott.

It would have to be done in the OS support as the compiler generated
code never gets to "see" all of the data at once. It handles it a
record at a time just as we do.

With the advent of result field DS I/O, Qualified DS, and Eval-Corr it
is not exactly hard to do yourself. The version we wrote up here uses
qsort to sequence the array:

and this piece by Susan was a simplified example using SORTA:

You could also store the data in a User Space (for example) which
would be useful in a web app where persistence is an issue. The
"secret" is to use a load-all approach and store the data in your own
"buffer" then you can sort any which way you want.

Of course there are those who prefer to use SQL and simply reload
using a different ORDER BY - but for the reasons mentioned in the
article we're not huge fans of that approach.

IBM (if there is an ounce of sense left in their bodies) are not going
to add features to an obsolete technology when all modern interfaces
offer data grids etc. which achieve this much more easily and with
complete User control.

I've always wondered why they didn't do that a long time ago.

However, I think a BIF is the wrong place for this. It should be a
DDS
keyword. It doesn't belong in RPG, it belongs in DDS as an
attribute of
the subfile itself. (And therefore available in all languages that
use
DDS subfiles.)

This should've been done 20 years ago. Now it seems almost too
late! I
mean, does it pay to put money into green-screen interfaces today?
