Would it surprise the net if I said that CPM Plus is not immune to viruses? The main thing in its favour/susceptibility is its control over error messages. I see some questions forming... Yes, I have written one -- it's about 3/4 K in length, and it's not leaving my write-protected floppy. -- If life is just a bowl of cherries, you'd better watch out for the stones.

I always knew that CP/M was not immune, but I really see no way to make a virus general enough to infect *every* CP/M system. For example, the boot drive on my DECmate is drive E:, not A:, and most of CP/M is stored in a file. So you couldn't infect my system by just scribbling all over track 0 of drive A:. -- =============================================================================== Roger Ivie 35 S 300 W Logan, Ut. 84321 (801) 752-8633 ===============================================================================
