TSO modifiable control variables (CLISTs)

Control variables provide information about MVS, TSO, and the current session, such as levels of software available, the time of day, and the date.

Your CLISTs can use the control variables to obtain such current information.

You do not have to define control variables. Control variables to which you can assign values are called modifiable control variables. The descriptions for this section are from the IBM publication, TSO Extensions: CLISTS.
