   The IBM 1070 Process Communication Supervisor was a dedicated process control system that ran as an extension under BOS "Relying on the BOS supervisor to handle ordinary physical and logical I/O operations (i. e., for cards, disk, etc.), the PC supervisor is specialized to the process control aspects of the user's program."

   An example of such a system is the HITAC S-3800, which was instruction-set compatible with IBM System/370 mainframes, and could run the Hitachi VOS3 operating system (a fork of IBM MVS). [40] The S-3800 therefore can be seen as being both simultaneously a supercomputer and also an IBM-compatible mainframe.

4. Transaction Processing Facility - Wikipedia

   en.wikipedia.org/wiki/Transaction_Processing...

   Transaction Processing Facility (TPF) [2] is an IBM real-time operating system for mainframe computers descended from the IBM System/360 family, including zSeries and System z9. TPF delivers fast, high-volume, high-throughput transaction processing, handling large, continuous loads of essentially simple transactions across large, geographically ...

5. MVS - Wikipedia

   en.wikipedia.org/wiki/MVS

   Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

6. COBOL - Wikipedia

   For example, a condition can be expressed as x IS GREATER THAN y or more concisely as x GREATER y or x > y. More complex conditions can be abbreviated by removing repeated conditions and variables. For example, a > b AND a > c OR a = d can be shortened to a > b AND c OR = d. To support this syntax, COBOL has over 300 keywords.
