This sounds interesting. I wrote such a routine some time ago for a CDC Cyber, and it was *very* useful. I was thinking about writing something like it for unix, but the problem seems to be the stack. I couldn't figure a way to initialize the stack from a core image. Anyone has any ideas how to perform that feat? -- Jack Jansen, {seismo|philabs|decvax}!mcvax!vu44!jack or ...!vu44!htsa!jack If *this* is my opinion, I wasn't sober at the time.
