ISPF Member List Statistics

The Member List Statistics displays detailed information about the members of a Partitioned Dataset (PDS). These statistics help users track and manage members efficiently, providing insights such as version numbers, creation dates, modification levels, line counts, and user IDs.

When you list the members of a PDS using ISPF, the statistics provide useful metadata that helps you understand:

Who created or modified a member.

How many lines a member contains.

When a member was last updated.

The current version and modification history of the member.
