For a while, Yale made it available free, but then entered into agreement with Computer Systems Research to sell it commercially. More recently, Cole Software (which is the author Dave Cole and, I think, one other person) purchased all rights from Yale. The product is still marketed by CSR. We have had the product for many years, having originally gotten the free version from Yale and later purchasing the commercial version. It is vastly superior to TSO TEST and can also be used to debug JES2 and other non-TSO programs. Our objection is to their copy protection. We have 6 CPUs, but only 2 licenses, since the product is used only on TSO and our delevopment system. If TSO gets moved to another CPU for any reason (say a hardware failure), we cannot use XDC there without getting a zap from Cole Software to change the CPU serial numbers in the program. This takes time, even more because there are only a couple of people who can make up the zaps. The price for a 6 CPU license is astronomical.
