Thanks Chris for answering so many questions. I should have read part 2 before 
answering part 1.

Anyone who doesn't express accolades for z/XDC has never used it properly. I 
couldn't afford it when writing my product which I found traumatizing after 
using it for so long. You can't say enough good things about z/XDC.

It now makes sense that this isn't actually automation but workload management 
possibly with scheduling. Very intriguing but a very different concept to 
automation.

With 40% HLAsm despite C++, it is obviously not a typical application.

For my product, everything privileged occurred during startup with the 
exception of PC routines. I was forced to use CSA because of 24 bit mode risk 
but it was only a few hundred bytes. Just needed PC routine number and SSCT 
entry. Probably unnecessary but I didn't want to risk it for so few bytes.

I did the same thing but on Intel and decided it was enough to know it worked.

Thanks, Jon.
