Hello namdevmate and welcome to the forums,

When posting a question, it is a good idea to include the question in the body of your topic - not just in the subject.

Your question is the main difference between an 01 and a 77.

A 77 can only be an elementary item. An 01 may be a group item or an elementary item. An 01 is automatically double-word boundary aligned by the compiler - a 77 is not.

If you'd like additional info, the COBOL manuals are availabel via the "Manuals" link at the top of the web page. If you read something that is not clear, reply back here and someone will be able to help clarify.
