I'd be amazed - quite utterly astounded - at this stage in its existence if
VTAM was causing problems with changes in mode table (LOGMODE) internal
format. I very, very much doubt that could be in any way anything to do with
the reported effect.
In any case, Debbie may be using the IBM-supplied mode table ISTINCLM - even
if the MODETAB operand is present but the selected mode table entry comes
from ISTINCLM.
Since we are talking about an effect happening deep within the SNA session
and the Unformatted System Services table (USSTAB) is customization applied
to the session between the secondary LU and the SSCP (VTAM), I just cannot
see any sense whatsoever in paying any attention to that table even if there
was a possibility of a change in internal format - which I also thoroughly
doubt.
I'm going to have to enrol you into the "grape-shot" school of problem
resolution. <g>
I can't say I'd ever performed this sort of research but isn't the need to
regenerate - including reassembly - customized tables one of the sorts of
issues covered by the documentation a systems programmer goes through when
planning a new release?
In fact the traces it might be useful to collect - if it's still possible -
are the NetView Session Monitor (NLDM) "complete PIU" (CPIU) primary traces
over the period in the session which demonstrates the change - both at the
V1R4 and V1R7 levels. That would be a clear starting point from which to
consider further tracing within the TSO component - perhaps such as you are
suggesting.
Actually I'm having a bit of a problem working out about what "spirit" you
may be talking.

That's the spirit. Guess what I'd do is reassemble the LOGMODEs and
USSTABs
or copy them to new names. Check with the emulator vendor if there are
fixes
for z/OS level, then if were still occurring I'd go with the traces and
breakpoints.
