Reset ISPF statistics panel fields

All the fields on this panel are described in the Libraries and Data Sets topic in the z/OS ISPF User's Guide Vol I, except these fields:

New Userid

This field is used to set the ID field in the statistics. Enter a new user ID here if you want to change the user ID the statistics are recorded under. It is required if you do not specify a new version number.

If you are updating the user ID but not resetting the sequence numbers, the statistics are updated but the data is not scanned or renumbered.

New Version Number

Enter a number here if you want to change the version number. This field is required if you do not specify a new user ID when resetting statistics. It is ignored if you are deleting statistics.

Reset Mod Level

Use a slash to select this option and reset the modification level. Deselect this option if you do not want to reset the modification level. A new version number is required to reset the modification level.

Reset Sequence Numbers

Use a slash to select this option and reset the sequence numbers. Deselect this option if you do not want to reset the sequence numbers. A new version number is required to reset the sequence numbers. Only standard (STD) sequence numbers are reset.

If the data is in packed format, there can be no sequence number processing. However, statistics for members in packed format can be created or updated if the sequence numbers are not being reset.

SCLM Settings

The SCLM setting is a bit that ISPF uses to determine what type of edit the file last had performed upon it.

1 SCLM: This bit is ON to specify that the last edit of this file was under SCLM control.
2 Non-SCLM: This bit is ON to specify that the last edit of this file was under control of something other than SCLM.
3 As-is: This bit is ON to specify that this copy operation transfers the current setting of this file as it already is.

Reset Date/Time

The setting of this option determines whether to reset the Last Modified Date or Time and the Creation Date of the file.

Reset Number of Lines

The setting of this option determines whether to reset the Current Number of Lines, the Initial Number of Lines, and the Number of Modified Lines settings. If this option is selected, the Current Number of Lines and Initial Number of Lines settings are set to the actual number of lines of the member.

The Number of Modified Lines setting is dependent on the Reset Mod Level and Reset Sequence Numbers options. If either of those are reset and the Reset Date/Time field is selected, then the value of the Number of Modified Lines is set to zero. Otherwise, the Number of Modified Lines remains as is.

Generate extended statistics

This option modifies the behavior of the Reset Number of Lines option.

When selected, line numbers greater than 65,535 are recorded in the PDS directory by Reset Number of Lines. More space is taken in the PDS directory by each member reset if this option is chosen.

When not selected, Reset Number of Lines records line number statistics up to a maximum of 65,535 lines and causes Extended Statistics to be cleared by Reset Number of Lines (if present).
