If you are talking about COBOL, why on earth did you post this question in the Compuware Tools forum? This forum is for Xpediter, Abend Aid, File Aid, and the like. I'm moving the topic to the COBOL forum.
There is a link to manuals at the top of the page. Click on it, find the COBOL Language Reference manual, and read up on the relational conditions, You will find the answer to your question in section 220.127.116.11 of the manual.
