Parameters

DIRECTION supports the following parameter:

directional-value

Direction in which the file is to be processed. The valid values are as follows:

FORWARD or F

Reads the file in a forward direction. For a KSDS this is in an ascending key sequence. This is the default value.

BACKWARD or B

Reads the file in a backward direction. For a KSDS this is in a descending key sequence. No input file concatenation is permitted when using this parameter value.

When processing a PDS and using the BACKWARD directional-value, the members are processed in ascending order, but the member's records are processed from the last physical record to the first.

Example 1

In the following example, for a KSDS, processing starts at the record with a key, or partial key value, of C'01234', and the KSDS is processed in descending keys from that point. If key C'01234' does not exist, processing starts from the next highest record key.

  DIRECTION(BACKWARD),
  RID(C'01234')

DIRREPORT

The DIRREPORT keyword controls the directory report when comparing PDS members. This keyword is valid only with the COMPARE command.

Syntax

DIRREPORT(A|M|S)

Parameters

DIRREPORT supports the following parameters:

A

All sections of the directory report are displayed.

M

Only those sections of the directory report that identify mismatched members are displayed.

S

Only a directory summary report is displayed.

Default: M

Example

This example syntax requests a summary directory report.
