The VS category is divided into two grades; VS1 denotes a higher clarity grade than VS2. Typically the inclusions in VS diamonds are invisible without magnification; however, infrequently some VS2 inclusions may still be visible. An example would be on a large emerald cut diamond which has a small inclusion under the corner of the table. [2]
Operating System/Virtual Storage 1, or OS/VS1, is a discontinued IBM mainframe computer operating system designed to be run on IBM System/370 hardware. It was the successor to the Multiprogramming with a Fixed number of Tasks (MFT) option of System/360 's operating system OS/360 .
OS/VS2 release 1 is an upgrade of OS/360 MVT that retained most of the original code and, like MVT, is mainly written in assembly language. The MVS core is almost entirely written in Assembler XF , although a few modules were written in PL/S , but not the performance-sensitive ones, in particular not the Input/Output Supervisor (IOS).
IBM released fairly minor enhancements of OS/VS1 until 1983, and in 1984 announced that there would be no more. OS/VS1 and TSS/370 are the only IBM [51] System/370 operating systems that do not have modern descendants. The Special Real Time Operating System (SRTOS), Programming RPQ Z06751, is a variant of OS/VS1 extended to support real-time ...
OS/VS1 Basic Programming Extensions (BPE) adds device support and VM handshaking OS/VS2 (Operating System/Virtual Storage 2, Virtual-memory version of OS/360 MVT) OS/VS2 R1 (Called Single Virtual Storage (SVS), Virtual-memory version of OS/360 MVT but without multiprocessing support)
OS/VS2 Release 3.8 was the last free release of MVS. In the late seventies and early eighties IBM announced: 5740-XE1 MVS/System Extensions (MVS/SE) MVS/SE improves the performance and RAS of OS/VS2 (MVS) 5740-AM6 Data Facility Device Support (DFDS) for OS/VS1 5740-AM7 Data Facility Device Support (DFDS) for MVS
