Edit database specification

The Data Base Specification screen is the first screen displayed in the edit conversation. There are two variations of this screen depending on whether you intend to use dynamic or static PSBs. For initial use, at least in a DL/I region type, we suggest you use a dynamic PSB because it is more convenient.

If both dynamic and static PSB processing are supported in the current environment, you can enter the XPSB command on either screen to switch to the alternate screen. If only one of these modes is allowed, the XPSB command results in the display of a message indicating that the alternate type of PSB is not supported in the current environment.

PSB processing for your ISPF session is set on the System Parameters screen. Edit - Data Base Specification Screen (Dynamic PSB) is displayed if you entered D in the Dynamic or Static field on the System Parameters screen. Edit - Data Base Specification Screen (Static PSB) is displayed if you entered S. For additional information, see System Parameters.

Use the DSN and ENV commands to view the data set concatenation list for the environment in effect for the current session or to select another environment for the session. For more information about these commands, see Primary Commands.
