OS/360 is the great great granddaddy of z/OS. At least in theory, a load module for problem state execution for an OS/360 Release 1 system will run, unchanged, on z/OS. Similarly, the Assembler source for this program will assemble, unchanged, on z/OS. Programs using anything more than very basic system facilities in OS/360 Release 1 will probably fail in z/OS; similarly not even the most basic object code from z/OS can be made to run in OS/360 Release 1 because some Assembler macros (GET, PUT, READ, WRITE, CHECK) generate instructions that do not exist in System/360Brad Cantrell wrote:...z/OS I believe is related to OS/360 which is one of the oldest operating systems, Im very curious how it differs with todays standard *nix OSes. ...
Somewhat incomplete and rather an over-simplification *whereas everything on unix seems to be just utilities that make system calls.
This was somewhat true in the 80's. . . What is the "C and unix" way to you? As compared to some other environment?Everybody just seems to blindly accept the C and unix ways of doing things.
