Ok, that's what OS X does... I always wondered ... So ideally, we should do something similar to the above and set some global bit somewhere telling the exception path to change the return address. In either case, the actual form of the loop becomes fairly irrelevant. I need to verify what's up with the 970. I noticed Apple has some additional weird tricks involving setting the DEC to a short value but setting POW without EE (though I don't remember for sure, I should dbl check their code). I suppose I should ask some IBM folks there. Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
