Compilation is necessary if 88 level is added?

[Rashmi Bansal]

Hi,

If there is a new 88 level variable is added in a copybook then should we recompile all the cobol programs using that copybook or is it ok not to compile them? Please help.

It would be wise to recompile all programs using the copybook since otherwise there may be duplicate variable names that you're not aware of and that could cause issues later on. Is it necessary to recompile every program using the copybook? No, it is not -- only those programs using the new 88 level have to be recompiled.
