You don't really mean that, do you? Or if you do, you'd better provide some
further explanation.

In the days following the availability of the various 3278 models, I needed
to support each on each type of controller. Because there were "non-SNA" and
SNA controllers, and, of the later, two types, channel-attached and
SDLC-attached, I devised an USS logon scheme which allowed the "model" to be
selected as M2, M3, M4 or M5 following the data field, the latter typically
used for the userid. Thus "tso mason,m3" was an example for the USS logon
command. This definitely required one customized mode table for "non-SNA"
attachment and one for SNA attachment, although, because of the 1536
outbound RU size limit for the channel-attached controller, I had one for
the channel-attached controller and one for the SDLC-attached controller.

Somewhat later, while teaching SNI Alias, a bright student from France
pointed out that IBM really didn't allow more than one mode table per
network(NetID) (logically concatenated to the supplied mode table ISTINCLM)
as could be deduced from the way the SNI Alias function worked. This point
was actually reinforced when the issue of running APPN with VTAM arose some
years later.

All this to say that, yes, it is possible to have a "variety of mode
entries" but, no, any selection from the "variety of mode entries" needs to
be manual as the example of my USS tables shows.

The only selection by the LU, and I mean the "application", not the
"terminal" LU, is by virtue of the Read Partition Query command and the
information returned in the Reply used when allowed to be used, the "query"
bit, as I explained in my previous post, and indicated by the use of the
X'03" specification in the penultimate byte of the PSERVIC operand.

If you have a variety of mode entries the terminal lu
will select the one best suited for the model it is.
