Hi,

I think you are moving this copybook data to the FD declared layout.
If so just increase the record length as X(102) and made changes in JCL(LRECL=102).

This is from my understanding, If I am wrong pls let me know

Thanx
Allu

hi kumar,

If you just changing the varibale then check which type of varibale it is like comp, comp-2 or comp-3. Based upon that see what is the size it is going to affect.
But as you mention in ur problem it is just X(4) to X(6), then over all length is going to change by 2 so you need to change the 01 level from 100 to 102. Same as in JCL as mentioned in other post.

As mentioned in all the previous post is it layout for any file defined in input-output section, please clear this doubt?
Hope i made your doubt clear. Let us know if you have any concerns.
