INPUT System Option—Input Data Set Processing Requirements

Use the INPUT system option to determine following:

• If tapes used for input are reset to the data center
• If data sets are re-chained upon input
• If the VMF is updated for BLP data sets
• If the VMF is updated for nonlabeled data sets
• If the VMF is updated for standard labeled data sets

This system option has the following format:

INPUT=[YES|NO]

[,CHN=YES|NO]
[,BLP=YES|NO]
[,NL=YES|NO]
[,SL=YES|NO]

INPUT=YES|NO

Specifies if tapes used for input are reset to the data center.

Default: YES

CHN=YES|NO

(Optional) Specifies whether to chain data set upon input.

Default: NO

Note: Applications that stack multiple data sets and then read the data sets back in can cause overhead due to re-chaining upon input. We recommend that CHN= be set to NO

BLP=YES|NO

Specifies whether to update BLP data sets if the data set name in JCL does not match VMF.

Default: YES

NL=YES|NO

Specifies whether to update NL data sets if the data set name in JCL does not match VMF.

Default: YES

SL=YES|NO

Specifies whether to update SL data sets if the data set name in JCL does not match VMF.

Default: YES

Example: INPUT System Option

INPUT=YES,CHN=NO,NL=NO
