As indicated in my post, I've had experience as a JES2 programmer
(about two decades worth). By that I mean, that once upon a time I
knew intimately the details of JES2's internal structures and logic,
and that I wrote many dozens of simple and complex mods to JES2 (and
HASP) for various employers from the '60s (at Rutgers, then Yale)
into the '80s (for DC bandits).
So my estimate, that implementing the support that I suggested would
not be too difficult and could be done in a matter of weeks, was
based on experience, not random guessing.
Certainly, my suggestion is potentially just a first step in a far
more complex set of issues that arise should you decide to expand my
idea into a more comprehensive job networking solution, but I was by
no means suggesting that. After all, as is well known, there already
are 3rd party solutions that deal with those complexities quite well.
All I was suggesting was a very simple mechanism by which jobs could
be guaranteed to run in the order submitted, nothing more, nothing
less. This guarantee is already there for some JES2 users (those with
CNVTNUM=1). Why not make it possible for everybody?

Entering real requirements to IBM is one way. He can also get a job
with IBM, become the head of JES2 and fight for his cause.
Saying that what I proposed is "my cause" is a bit of an
overstatement. ;-) I was just making a suggestion, not a demand. As
I've already noted, I already have my solution to the problem.
Saying that I wanted "JES2 to handling scheduling" also is an
overstatement. All I did was suggest a very simple way by which JES2
could be changed so that it could guarantee job sequencing, should a
user want it. That is a far cry from job scheduling.

And that JES2 doesn't do device setup and highwater mark
reservation, and that JES2 doesn't verify data set availability, and
that JES2 doesn't do better syntax checking, and that JES2 doesn't
check for duplicate DDNAMEs within a step, and that JES2 doesn't
balance load across systems, and ...
If JES2 did everything that JES3 does, it wouldn't be JES2 any more,
would it? Am I right in assuming that JES3 costs more than
JES2? Doesn't the vendor, then need to provide differentiating
features to justify the expense? Of course, it's only human nature
to wish that one's only favorite feature were added as an
enhancement to the lower priced product.
I am not suggesting a convergence between JES2 and JES3 (although
there has already been a considerable amount of that since the old
HASP vs. ASP wars). I also am not suggesting anything that would be
complex or difficult to implement (such as the several JES3 features
that you referenced).
I was just saying that it would be such a simple thing to do, and
that because it is so simple, I feel that it's a shame that IBM doesn't do it.

I don't think that you are correct (at least not directly). IIRC,
JES2/JES3 is just a choice you make when ordering a system. There is
no additional charge for either. (But also IIRC, doesn't JES3 consume
more resources than JES2 and so costs would be increased in that way?
Our are my prejudices obsolete?)
