Post by nrajini » Mon Oct 06, 2008 2:27 pm

If we are changing a copybook .Say adding a new field , do we have to compile all the modules which are using this copybook .. If yes pls explain

or do we have to compile only those modules which uses the newly added variable?

Suggesting method is to compile all the programs which are using this copy book.

There are three cases , i would like to discuss here.

1) Copy book length got changed.
I strongly suggest that, you better compile all programs using that copy book.

2) New field is NOT added at the end. ( added between fields etc.. )
I strongly suggest... compile all programs using that copy book

3) Copy book length not changed, added new field in the free space available ( FILLER) / at the end of the copy book.
It is not required to compile the programs, if it is not using the new field.
