I've forgotten how to do it, but there's some bizarre way to do a TPUT
to session mangler.  If it's not active, I think you'll get a return
code indicating such.  Check the Session Manager Logic Manual.

There's only one 0A5D in SMPUT.  Put a breakpoint there and look at
the regs.  Notice that R15 has something odd in it.  What I see from
doing this on a command of 'SMPUT /X/ SMIN' is as if the following
were coded:

        TPUT  data,length,ASIS,USERIDL=user
data    DC    C'X'
length  EQU   *-data
user    DC    C'*ADF',X'0000',CL8'SMIN'

Can you be more specific?

It sounds like you're trying to control the screen layout.  Any time I
see this type of desire, I have one comment:  Use FULLSCREEN.  If you
don't, then you won't be able to have complete control, and the user
will lose other messages.  For example, if you're not using FULLSCREEN
and you clear the screen yourself, picture the following sequence:

   Your program writes a prompt to the terminal
   Your program requests input from the terminal
   Another user or the operator or JES2 or whateverelse sends a line
      to the user
   The user types his input and hits ENTER
   Your program clears the screen and writes more data
   The user has lost the message the other user/operator/etc, and
      may not have even seen it flash by.

If you want complete control over the screen, you must use TPUT
FULLSCREEN, along with STFSMODE ON.

Yes.  Not be snide, but... so?  Again, you haven't explained what your
actual problem/need is.  You're fishing for information without
supplying enough information for an intelligent response.  It would be
much easier to correctly answer your question if you described
specifically what you're trying to accomplish.

That's true, since those functions are either meaningless or cannot
be implemented under session manager.

I always thought that was a design flaw in SM.  We run PIE MultiTSO,
which makes that kind of moot.  I have SM in one session on non-SM in
others.  The biggest problem is that I want SM in more than one PIE
session, and that can't be done because SM is hooked in in the wrong
place.
