Many years ago (1980s) I did encounter a VM product that tested for several forms of tracing (PER, VM TRACE command) being on, and took different code paths and even disabled PER at times. But it was (and is) very rare. What would be the point of cracking or reverse engineering mainframe software? It is a rare piece of software that has a lot of value locked up in a secret-sauce algorithm. Most software, imho, has its value in the support services rather than magic code. To be sure, someone could license a mainframe software product, and then defeat the licensing scheme. But to what end? I have worked for several ISVs over the years, and I have yet to see any serious evidence of any of our products being stolen by either a customer or a distributor. (Yeah, yeah - I know; if they were successful we wouldn't know about it.) I'm not saying it never happens, but realistically, what kind of customer would run such software? Or to put it another way, what would be your sales pitch for PC-like tools to protect mainframe software?
