System defaults are preset values the system uses when setting up a user profile in the Information Center Facility. As an administrator, you can create or modify these defaults.

The Information Center Facility uses the system default ISPF profile. ISPF/PDF maintains a set of values that can be modified for each user. Each ISPF/PDF user can modify these defaults by selecting the PDF profile option (usually option 0). The enroll process of the Information Center Facility creates this default set of values for the user being enrolled. You can modify the defaults for the user during the enroll process. You can also modify the initial set of defaults supplied by ISPF/PDF using the SYSDEF option on the Administration main menu panel. When you modify the initial defaults supplied by ISPF/PDF, a local copy of the profile is maintained by the Information Center Facility. In this case, the defaults supplied by ISPF/PDF are no longer used. You may want to change the defaults when the standard defaults no longer apply to the average user being enrolled. Changing the system defaults will require you to do less customization when enrolling users.
