Another look at a VM/IS release 1.5 system from 1988. This time, we're looking at a (somewhat out-of-date for this system) OS/VS COBOL from the 70s, PL/I Optimizing Compiler, and, a C compiler that can compile C89 before C89 was even a thing (although I didn't nearly do it enough justice in this video). We also take a look at the configuration details of RSCS, VTAM, TCP/IP, and PVM.

Next up: using VM/IS as an end user.
