Changing Logical Record Length

IEBGENER is used to produce a reblocked output file. The output file can contain either fixed-length or variable-length records that is different from input record length. Any fields that are not coded may contain unpredictable data.

Practical Example -

Scenario - Create new PS file with length 70 different input file length 80.

Input PS File - MATEPK.IEBGENER.INPUTPS

JCL -
