Summary -
In this topic, we described about the OUTFIL Creating multiple identical copies with detailed example.
OUTFIL can be used to create multiple datasets with the same data. The most known reason behind multiple datasets creation is backups.
If the same dataset used to take backup on different areas like disk, tapes or local site, OUTFIL will be most useful. The same can be achieved with OUTFIL and the FNAMES parameter with an OPTION COPY statement.
The FNAMES parameter identifies the DD statements in JCL for output data sets by their DDnames.
Syntax -
OPTION COPY OUTFIL FNAMES=(DDNAME1, DDNAME2,…..,DDNAMEn)
| Name | Description |
|---|---|
| DDNAMEn | DDNAME is eight character’s name that representing the actual dataset in JCL. |
Example -
Create two output files with the same data in the input file
Input File: MTHUSER.SORT.INPUT01 - FB file of 80 length

Explaining Solution:
OUTFIL FNAMES=(OUTPUT1,OUTPUT2) - copies all the records to the output files OUTPUT1, OUTPUT2 to create to identical copies.
