Hercules is a computer emulator allowing software written for IBM mainframe computers (System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems ...
The z/OS operating system (MVS' most recent descendant) also has native support to execute POSIX and Single UNIX Specification applications. The support began with MVS/SP V4R3, and IBM has obtained UNIX 95 certification for z/OS V1R2 and later. [5] The system is typically used in business and banking, and applications are often written in COBOL.
On May 19, 1992, IBM announced [10] DFSMS/MVS, 5695-DF1, replacing MVS/Data Facility Product (MVS/DFP) Version 3, 5665-XA3, Data Facility Hierarchical Storage Manager (DFHSM) Version 2, 5665-329 and Data Facility Data Set Services (DFDSS) Version 2, 5665-327. DFSMS/MVS also replaced utilities and service aids.
Its interactive environment is comparable to that of a single-user PC, including a file system, programming services, device access, and command-line processing. (While an earlier version of CMS was uncharitably described as "CP/M on a mainframe", the comparison is an anachronism; the author of CP/M, Gary Kildall, was an experienced CMS user.)
CLIST (Command List) (pronounced "C-List") is a procedural programming language for TSO in MVS systems. It originated in OS/360 Release 20 and has assumed a secondary role since the availability of Rexx in TSO/E Version 2. The term CLIST is also used for command lists written by users of NetView. [1]
Universal USB Installer (UUI) is an open-source live Linux USB flash drive creation software. It allows users to create a bootable live USB flash drive using an ISO image from a supported Linux distribution, antivirus utility, system tool, or Microsoft Windows installer. The USB boot software can also be used to make Windows 8, 10, or 11 run ...
TSO/E is a base element of z/OS. Before z/OS, TSO Extensions (TSO/E) was an element of OS/390 and was a licensed program for the MVS and MVS/ESA System Products. [4] Since all z/OS installations usually have both TSO and TSO/E functions installed, it is normal to refer to both TSO and TSO/E as "TSO".
OS/390 was introduced in late 1995 in an effort to simplify the packaging and ordering for the key, entitled elements needed to complete a fully functional Multiple Virtual Storage (MVS) operating system package. These elements included, but were not limited to:
