Time Sharing Option

Time Sharing Option (TSO) is an interactive environment. TSO commands can be used by the scripting language CLIST.

Time sharing was introduced as an optional feature of the operating system with MVT. TSO makes the facilities of the operating system available to programmers at remote terminals to develop, test and execute programs conveniently, without the job turnaround delays typical of batch processing. It offers the use of data entry, editing, and retrieval facilities. It also allows the management of an installation to dynamically control the use of the system's resources from a terminal.
