Binyamin, I do follow the discussion with great interest, but this question:
> What parts of code (or the operating system) would be "astonished" to > find that an SRB is running in a non-system key? made me raised more than an eyebrow... I do know an operating system that throws up everything (as opposed to "astonished") when it encounters a programcheck (other than paging related) in code running in key 0. And it is the only other one than runs a native CICS. Wanna know which? -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
