What is TSO command in mainframe?

Time Sharing Option/Extensions (TSO/E) allows users to create an interactive session with the z/OS® system. TSO provides a single-user logon capability and a basic command prompt interface to z/OS. ISPF users include system programmers, application programmers, administrators, and others who access z/OS.

Consequently, what is TSO in mainframe?

Time Sharing Option (TSO) is an interactive time-sharing environment for IBM mainframe operating systems, including OS/360 MVT, OS/VS2 (SVS), MVS, OS/390, and z/OS.

One may also ask, what is the difference between TSO and ISPF? TSO also provides users with a limited set of basic commands; using this set is sometimes called using TSO in its native mode. ISPF is a menu-driven interface for user interaction with a z/OS system. The ISPF environment is executed from native TSO. ISPF provides utilities, an editor and ISPF applications to the user.
