The following sections give an overview on the exits that TSO/E provides for functions and commands. Also shown are the exit names if they must follow a naming convention.

Many TSO/E exits receive a TSO/E standard exit parameter list. Other TSO/E exits receive parameter lists that are different from the standard parameter list and which vary for each exit. To distinguish the exits that receive the standard exit parameter list from exits that receive different parameter lists, this document refers to TSO/E exits that receive the standard list as standard-format exits. TSO/E standard-format exits describes standard-format exits and the standard exit parameter list. In the following sections the standard-format exits are designated by a footnote¹ following the name of the exit.

The individual descriptions of the exits in this document describe the parameter list each exit receives. The descriptions also describe whether TSO/E provides a default exit routine for the exit and if so, what processing the default exit routine performs. TSO/E does not provide default exit routines for the standard-format exits.
