Settings (option 0)
The Settings option allows you to display and change a variety of ISPF parameters at any time during the ISPF session. Changes remain in effect until you change the parameter again, and ISPF saves them from session to session. This topic explains how to use the fields on the ISPF Settings panel and the action bar choices.
If you select option 0 on the ISPF Primary Option Menu, this panel is displayed.

This facility can also be started from any command line with the SETTINGS command, or from the Settings choice on the Menu pull-down on any action bar where it is available. Typically, the Settings facility should be included as an option on an application's primary option menu or as a choice on a pull-down on an application's primary option menu.
