Personal lists (library and data set) can be shared with other users on the system. Tables ISRPLSHR for data sets and ISRLLSHR for libraries are shared lists. They are kept in an ISPTLIB concatenated data set. Private lists are tables ISRPLIST (for data set lists) and ISRRLIST (for library lists). They are kept in the ISPPROF user profile data set.

Shared lists are created by using ISPF option 3.3 to copy an existing personal list table from a user profile data set to a data set concatenated to ISPTLIB. You must rename the table to ISRPLSHR (for data set lists) or ISRLLSHR (for library lists) during the copy operation. You can open a shared list and use it; you cannot update or delete a shared list. You can also save it to a private list using the Save As function available from the Personal Data Set Lists panel (ISRPLTAB) and the Personal Library Lists panel (ISRLLTAB). You must save the shared list to a personal list before you can retrieve names from it.
