Are you really saying that just because the same code compiles "cleanly" with the old and new compilers, that you think this is all the testing you need to do? If so, I think I have a canoe to sell you that is just as was tested to be the same thing as the Brooklyn Bridge<G>. IBM certainly "attempts" to insure that (assuming the SAME compiler and run-time options) that "old and new" compiled code will: A) yield the same results B) "perform comparably" However, I don't know of many shops that ASSUME this will always be true (or any place that IBM guarantees that this will be the case; only that they will accept defect reports when it is not true.). Certainly if you don't spend a LOT of time researching "new" compiler options (for example) - much less changes in default compiler and run-time options, I would HOPE that you would do SOME "systems" testing to insure acceptable production performance before migrating (en mass) all the newly compiled code into production. Bottom-Line: (to me - and YMMV) if you do a mass recompile, then you really, REALLY need to do extensive performance AND "same result" testing - at least for a fairly large "sample" of programs/applications. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
