(snip) > [Yes, OS subtasks started with ATTACH all run in the same address > space. -John] Well, all of OS/360, OS/VS1 and OS/VS2 runs in one address space. For OS/360 all real addresses, for OS/VS1 and OS/VS2 a single 16MB virtual address space. (MVS is where they started using separate address spaces.) Much of the OS is key zero, and readable by everyone. But I think you are agreeing that subtasks run with the same key as the parent. -- glen [Yes. Now back to compilers. -John]
