I will assume that since you specified the VM/TCPIP stack does the DIAL
command to VM/VTAM you are using the SCEXIT provided by IBM. 
If so what I would do is put all the terminals that need a specified LU in
the CICS partition in a different subnet. Then in the provided SCEXIT in or
around line  155-158 there is a "TEST" that determines the IP addr of the
client. You can change the REXX coding to DIAL a CICSVSE ADDR instead of
DIAL VTAM (for VM) in the CICS Virt Mach, you can then have a pool of TCT 
Addresses that can conform to your needs. Yo can also DIAL a VM/VTAM address
with a certain address but this is going to to a little more REXX coding.

It has been awhile but this sounds like you need a VTAM Session
Establishment exit where you dynamically change the attributes of the
terminal before making the connection since at this time you should have
the terminal LUNAME and the CICS APPLID.  It could be the DLOGMOD,
FEATUR2 or both.  Then the next question would be how to rest the
terminal id back to its original settings after the CICS connection is
dropped.  This would allow logging onto various CICS regions from the
same logical terminal.

It would be easier if you could inflict upon the users what virtual
terminals are connected to what CICS at the DIAL command, but you would
have to read the user's mind at that time.  This would not prevent
logging onto various CICS regions from the same logical terminal.

I'm in need of a solution to a weird problem....

We have VM/VTAM control all of our real terminal controllers and the VM
TCPIP stack does a "DIAL VTAM" so all terminals get the same look and
feel.  They come into a USSTAB (either the SNA or non-SNA version) and
are able to select the CICS system they want.

The 12 VSE VTAMs only define the cross domain services and the CICS
applids.

The 29 CICS systems, all use autoinstall.

That part is all simple.....

Our production CICS systems for inhouse developed applications.... 
well some of the applications were written in the mid '70s.  I came into
the CICS world with CICS 1.4, and these applications may have been
written for a prior CICS release.  Anyway, they don't have "attributes"
specified in the BMS maps.  The application programmers coded them in
the application program.  i.e. they moved "what they thought" was proper
attribute bytes to their maps.

This worked fine.  That is for non-extended data stream devices.  And
all of our VM/VTAM definations define all devices as non-EDS.

Well, now I need EDS capable devices but only on certain CICS regions. 

When I changed the VTAM devices to support EDS, we got all sorts of
weird colors, blinking and reverse video on our old applications. 
Apparently, when the Cobol programmers created their attribute bytes
(and it wasn't copy books, it is inline code that was redeveloped with
each new program...or so it seems), they only cared about the bits they
needed (highlight/normal) and the rest of the bits, didn't bother
anything....until now.

What I want to be able to do is, on a CICS by CICS basis, setup whether
that system can handle EDS.  My understanding of the negoiation of the
bind, is when there are conflicts, they step down to the lowest common
attributes.  I would rather not make changes to our current production
systems, but rather to the systems that need EDS.  But I think those two
conditions are in direct conflict with each other.

What are some good ways of making this type of change?

Thanks
