TPX

   <operating system> (TPX) A multiple session manager used to
   access {mainframe} applications.  It was written by {Morgan
   Stanley}, acquired by {Duquesne Systems} and is now owned by
   {Computer Associates}.  TPX allows you to work in multiple
   mainframe applications concurrently; lock and unlock your TPX
   screen; place your applications on hold; logon to TPX from a
   different terminal without losing your place; customize your
   TPX menu and send a screen image to another TPX user.

   TPX runs on {MVS} and {VM}.  On VM, like {VTAM}, it uses the
   MVS-like facilities of {GCS}.  It has a complete {scripting}
   facility and lets you see other user's sessions.  The
   {client-server} version allows each managed session to open in
   its own window.  Richard Kuebbing has built a complete e-mail
   system into it.
