What is an in line PERFORM? When would you use it? Anything else to say about it?

The PERFORM and END-PERFORM statements bracket all COBOL II statements between them. The COBOL equivalent is to PERFORM or PERFORM THRU a paragraph. In line PERFORMs work as long as there are no internal GO TOs, not even to an exit.The in line PERFORM for readability should not exceed a page length - often it will reference other PERFORM paragraphs.
