R — reset (create/update) ISPF statistics

Use option R either to create statistics in a library that does not currently have them, or to update statistics in a library.

The New Userid field is optional for option R. If you specify a user ID, it is placed in the ID field of the statistics. If you leave the New Userid field blank and select a member without statistics, the ID field of the statistics is set to the current user ID.

Either a new user ID or a new version number is required when you use this option. When you specify a version number, the statistics are created or reset as follows:

Version Number: Set to the specified value.
Modification Level: Set to zero if requested; otherwise, unchanged.
Creation Date: Set to current date in the national format.
Change Date: Set to current date, in the national format, and time.
Current No. Lines: Set to the current number of data records.
Initial No. Lines: Set to the current number of data records.
No. Modified Lines: Set to zero if the Reset Sequence Numbers field is selected.

If you have requested updating of the modification level and resetting of the sequence numbers, the last two digits of each sequence number are set to zeros. Otherwise, they are not changed.

If you have requested updating of sequence numbers, the data is scanned to determine if valid, ascending sequence numbers are present in all records. If so, the data is renumbered. Otherwise, the data is assumed to be unnumbered and renumbering is not done.
