RE: Defining a function key...

Just a quick note from a geezer, er, someone in their late youth; the S/3
did not use the 5250 data stream, it was 3270.  There weren't Kx indicators
because there weren't command keys.  There were several PA keys and several
more PF keys.  With CCP we had to check the AID byte, and it was included in
the I/O buffer.

I therefore find using the AID byte intuitive because that's what I started
with, although we were much closer to the datastream back in the day.  The
S/32 Kx indicators always seemed exotic to me.  Not that they were hard to
read, but they weren't familiar.  I haven't used either in many moons,
because I've been working with mostly S/38 code and nobody around me is
comfortable with Kx or the AID bytes.

For what it's worth, I have to teach new RPGers all the indicator
techniques, because they'll encounter them all working here.  Many of our
clients have their own staff and will make changes to our code in their own
style...  In my experience, the S/38 'define it in the DDS and share the
indicator with thr RPG' is the easiest for them to grasp because of the one
to one correspondence.
