The big advantages of the IBM mainframe architecture have always been application upward compatibility, I/O throughput, and RAS (reliability, availability, and serviceability). <SNIPPAGE> Give that staggering number of financial transactions processed on a daily basis, over 90% of which is done on large-scale IBM mainframes, is it not strange that you have never heard of a mainframe virus? IBM RAS and IBM Security (whether implemented via IBM RACF, CA ACF/2, CA-Top Secret Security, or some other External Security manager (ESM)) is what keep these systems running. <SNIPPAGE> Actually, there are a few of them. I had made the same statement circa 1990, and I was pointed to an experiment that had been done to prove that an MVS based virus could be accomplished. One of the reasons for Production Control types to only accept source and do their own compiles and linkages is to prevent what could be malicious code from being copied and then infecting a business' production load libraries.
