Hi Chuck, > If I change a logical file to exclude records (where before it didn't > exclude records) and run a CHGPF against the DDS to change the logical, > will it generate a level check? There are different types of level checking, but the one that causes programs to end in error is the "record format level check." Since excluding records does not change the record format, it will not cause a record format level check... When you have a simple question like this, it's a good idea to try to test the situation yourself before posting it to a list. You can create an LF in a different library that does the record omission, and modify your library list and see if the existing programs blow up. If they don't, you know that it's safe and can change the version in the production library. That way, you'll know for sure, AND you'll have saved yourself time getting an answer.
