To name an ISPF library, you must specify at least a project, group, and type. For example:

Project  . . ISPFPROJ
Group  . . . TEST
Type . . . . PLI

Project

The common identifier for all ISPF libraries belonging to the same programming project. This name must be your user ID unless you are using a specific project name that has been predefined in the MVS™ master catalog.

Group

The identifier for a particular set of ISPF libraries, that is, the level of the libraries within the library hierarchy. For example, the group name of your private library could be PRIVATE or perhaps your first name, such as Joe in the example in Figure 1.

Type

The identifier for the type of information in the ISPF library, such as PL/I, SCRIPT, or PANELS.
