PDS processing options

A PDS Processing Options screen, as shown in PDS Processing Options Screen, is displayed when the dataset name or Record layout dataset name on the Input Dataset Specification screen refers to a partitioned dataset (PDS or PDS/E). It is used to specify member processing values that control whether to include extra record information and maintain PDS statistics. In addition, you can specify member selection values to choose members based on a name mask, name range, the userid for last modification, and creation and modification date ranges.

In most cases, the PDS Processing Options screen allows you to display the Member S/X (Select or Exclude) screen before specifying or applying aging criteria by entering a Y (Yes) in the Display Member List field.

Many PDS processing options are preset with default values at installation time. Others have no effect unless a value is entered in the field. The options that are available vary with the type of data set being processed and according to File-AID/Data Solutions function.

To display a nonselective member list, leave all member selection options blank on the PDS Processing Options screen and press <Enter>.

When you enter a partitioned dataset name and specify an * (asterisk) for member name, File-AID/Data Solutions bypasses the PDS Processing Options screen and uses the default values as specified on the Processing Parameters screen, option 0.4, Processing Parameters Screen.

Field Descriptions

The following list describes all PDS processing options that File-AID/Data Solutions can present.

Maintain PDS statistics

This parameter controls the updating of PDS member statistics when changes are applied with the Update function. Specify one of the following values:

Specify Member Selection Options:

Member name mask

Specify a member name mask to select a subset of members based on the mask criteria. A pattern member name or mask consists of explicit characters or a combination of explicit and pattern characters. For more information, see Pattern Member Names.

Member name range

Specify a member name range to select a subset of members based on the characters in the member name. The endpoint member names (FROM and TO) can be complete or partial and are included in the member list when found. Pattern characters are not allowed.

If the FROM member field is blank and a TO member is specified, File-AID selects the members less than or equal to the TO member padded with high values.

If a FROM member field is specified and the TO member is blank, File-AID selects members greater than or equal to the FROM member padded with low values.

Entering the same characters in the FROM and TO fields selects all members beginning with those characters.

Last modified userid

Specify a user identification range to select a subset of members based on the user ID that last updated and saved a member. This information is a PDS statistic that is stored in the directory.

The endpoint userids (FROM and TO) can be complete or partial and are included in the member list when found. Pattern characters are not allowed. As with member name range, the FROM field is padded with low values and the TO field is padded with high values.

Members without PDS statistics, because they were not created (STATS OFF) or the statistics were deleted, are not selected.

Creation date

Specify a creation date range to select a subset of members based on their creation date(s). This is a PDS statistic that is stored in its directory.

The endpoint (FROM and TO) dates can be complete or partial and are included in the member list when found. Leading zeros are required when specifying the year, month, and day.

If the FROM date field is blank and a TO date is specified, Data Solutions selects all members created on or before the specified TO date.

If a FROM member date is specified and the TO date is blank, Data Solutions selects all members created on or after the specified FROM date.

Entering the same dates in the FROM and TO fields selects members created only on that date. The two-character year is assumed between 1960 and 2059. Partial creation dates are treated positionally (YY/MM/DD) and are padded with default values.

For example, if you enter blanks the default FROM value becomes 60/01/01 and the TO value becomes 59/12/31. If you enter 85, the defaults are 85/01/01 and 85/12/31. If you enter 85/09, the defaults are 85/09/01 and 85/09/30.

Members without PDS statistics, because they were not created (STATS OFF) or the statistics were deleted, are not selected.

Modification date

Specify a modification date range to select a subset of members based on the last modified date(s). This is a PDS statistic that is stored in its directory. The last modified date is updated with the current date each time a member is updated and saved.

See the description of the Creation date field for more information on specifying a modification range. The specifications are identical.

Members without PDS statistics, because they were not created (STATS OFF) or the statistics were deleted, are not selected.

Display member selection list

Specify Y (Yes -- default) or N (No). This field controls the display of the member S/X (select/exclude) list after PDS processing options are applied. If Y is specified, a member S/X list is displayed. See Member Selection Lists. When N is specified, a member list is not displayed after the PDS processing options are applied.
