Call me conservative after many years in this business but I say Yes. In my experience optimization sometimes exposes bugs that previously were masked. I have little experience with COBOL, but COBOL is notorious for allowing invalid constructs like array subscript over-cleverness.

So, if someone compiles their COBOL program without optimization and tests it, then compiles it with optimization before putting it into production, does it need to be tested again? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
