Hello,
And what is the change to be made? When posting code, data, jcl, etc the Code tag should be used to preserve alignment and improve readability. Your "copybook" has been Code'd
How is the file referenced (programs, utilities, etc.)? |

It is referenced as an input file in an sort step. and it has a control card which has an program which is actually super linked.
MODS E15=(JMCLKLOD,30000,STEPLIB,N),
INPFIL EXIT
OUTFIL EXIT
The actual change needed is to a increased a field length for eg.
JMKXCO# DS PL2 to PL3 |

Hello,
You need to look at the module executed by the E15 exit. It will show how the file is really used. There are probably other processes that access this file as well. . .
It will help you to hex dump a few records and look at the actual content of the records. |

Hello,
Have you determined what the file contains and what this is used for (other than this sort exit)? |
