(PC) Message-ID: <0011.9106171414.AA16331@ubu.cert.sei.cmu.edu> Date: 14 Jun 91 20:09:32 GMT Sender: Virus Discussion List Lines: 15 Approved: krvw@sei.cmu.edu If you want to find out what's in memory at a particular location, and you're lucky enough to be using a Zenith computer (at least, on every Zenith I've seen except the Eazy-PC -- it had a non-Zenith BIOS), you can press ctrl-alt-return (enter, whatever), at pretty much any time, and be thrown into what Zenith calls a "monitor program" -- the same one you get when you press ctrl-alt-ins. Only in this state, it shows you the memory contents at the current location. You can change, examine, etc. from this point. If you type "g" and press return, you'll go back to executing the program where you left off, assuming you didn't mess with anything important. It's essentially a built-in debugger. Apologies to anyone who doesn't have a Zenith, but look on the bright side, this feature can cause incompatability problems on rare occasions.
