Hi
I am enhancing my program like my emp-id is increased in number of bytes
while doing so, what in JCL has to be checked and changed

Hi,

Is this a C program or a Cobol program.

First we need to check the DCB parameters mentioned in the program for that particular step where it is calling the Dataset and change the LRECL if mentioned.

In the JCL if allocating the Dataset need to change the LRECL of that particular dataset to the number of bytes added.

Thanks,
Gau

We're assuming that the emp-id is in a file, either I/P or O/P or both.

If you're passing that emp-id on to other files created in your pgm, you must assure that all pgms downline from yours have been modified to accommodate this change.

If the pgmrs who "own" these pgms are responsible for changes these to their prms, your responsibility is ended once they have been notified. If. on the other hand, you're responsible to make these changes too, you must trace the use of ANY file that uses that emp-id, regardless of what it may be called by other downstream pgms and make the appropriate changes for any files/databases/etc. that may use it.

If that's the case, I think you may have found a career for yourself.
