Well - there are at least commands to show PTE mapings and also to read and write memory and register locations in various styles. It's possible, but still hard work to get a function address with this so it's of limited use it that case. Or can we see the trapping codeaddress in any register? > There's something called XDELTA that I've accidently entered on a > couple of occasions.

I think I've already seen it by accident too. IIRC it was a single letter command to enter, but I already tested every single letter on NoName. Possible that NoName's SRM just isn't good enough - will recheck on a decent machine later. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
