Terminal Productivity eXecutive
(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.
