RE: Green screen - it's time is over/CODE/400

Well, it depends upon what your very special error is!  I had problems too
(/COPY statements) but Violaine isolated it to a problem with the real
compiler code and some of the "H" options.  Of course, a first-time verify
is slower than a 170 with a cranked-down CFINT and the cache function is
crude (it's not smart enough to know what source member/files have changed).

I don't have time for troubleshooting either; hell, I don't have time for
anything productive now that I'm reading your posts!  I was fired by the
Farr-Coulthard show at the Rochester March pre-announcement meeting; came
back; tried to get the damn thing to work; and ended up writing a letter to
the iSeries High Commander questioning the Group's commitment to AD tools.
But CODE/400 is one of those times when effort and persistence is worth it
and I think the Toronto group is doing the best they can, given the lukewarm
support of the iSeries management group.  Of course, CODE/400 means nothing
to the rest of IBM because it's not Linux...

Reeve,

You got VERIFY to work...?!?  I watched post after post on the IBM
newsgroup.  People all had the same exact error as I got, on the same exact
line.  This went on for months.  Never was resolved.  This was around Feb to
May of this year.

I'd try it every now and then with the same result.  I don't have that kind
of time.  Since that was the main feature I was looking for, I gave up.  And
I don't generally give up easy.

(I should say it was GREATLY improved on when I looked at it in years past,
but...) I want to put my time into learning how to make best use of a tool,
not figuring out how to make it work.  Maybe some places have dedicated
staff for that kind of troubleshooting.  I don't.

jt
