Yes. The MVS ones for example test assembling, linkediting and running a program, creating an abend (and therefore testing recovery routines). There are also IVP's for components of MVS, such as DFSMS. I appreciate that its always necessary to test what is important to you at your own site. And also that z/VM is such a stable piece of gear. I guess I was just trying not to reinvent the wheel, if such a wheel already existed. Thanks for all the good ideas in terms of testing, from y'all (or should that be all yer?).
