Use JCL to change the out file in a variable circumstance

Post by jctmaia » Thu Oct 13, 2016 7:16 pm

Hi everybody,
I would like to know how I could use a variable condition from “in” file to change the “out” file. For example:
In:
0000000001345HEADER100000
0100000002016DETEST100000
0100000002016DETEST200000
9900000001345TRAILER10000
0000000001540HEADER200000
0100000002016DYTEST100000
0100000002016DYTEST200000
9900000001345TRAILER20000
Out:
0000000001345HEADER100000 013450001
0100000002016DETEST100000 013450002
0100000002016DETEST200000 013450003
9900000001345TRAILER10000 013450004
0000000001540HEADER200000 015400001
0100000002016DYTEST100000 015400002
0100000002016DYTEST200000 015400003
9900000001345TRAILER20000 015400004

The header always starts with “00” and trailer always starts with “99”. I need to copy the number that is only in header to all registers unit trailer.
Should be perfect to do this just using JCL, but I’ve already tried a lot of things unsuccessfully. Maybe there is something I didn't do yet.
Thanks for your help!
