The goal of the contest was to provide students with the opportunity to experience working with mainframes. [3] The contest was created in part to increase the number of mainframe skilled individuals in the computing workforce.
IBM Z Development and Test Environment can be used for education, demonstration, and development and test of applications that include mainframe components. The Z390 and zCOBOL is a portable macro assembler and COBOL compiler, linker, and emulator toolkit providing a way to develop, test, and deploy mainframe compatible assembler and COBOL ...
The primary operating systems in use on current IBM mainframes include z/OS (which followed MVS/ESA and OS/390 in the OS/360 lineage), z/VM (which followed VM/ESA and VM/XA SP in the CP-40 lineage), z/VSE (which is in the DOS/360 lineage), z/TPF (a successor of Transaction Processing Facility in the Airlines Control Program lineage), and Linux ...
The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
IBM's operating systems z/OS, z/VSE, z/TPF, and z/VM are versions of MVS, VSE, Transaction Processing Facility (TPF), and VM that support z/Architecture. Older versions of z/OS, z/VSE, and z/VM continued to support 32-bit systems; z/OS version 1.6 and later, z/VSE Version 4 and later, and z/VM Version 5 and later require z/Architecture.
The IBM 704 is the model name of a large digital mainframe computer introduced by IBM in 1954. Designed by John Backus and Gene Amdahl, it was the first mass-produced computer with hardware for floating-point arithmetic. [1] [2] The IBM 704 Manual of operation states: [3]
Starting with System z9 running z/OS 1.7, IBM offered the multiple-subchannel set facility, which allowed up to four independent sets of 64 Ki subchannels. [3] The installation was responsible for defining the Input/Output Configuration Data Sets (IOCDS's), and the operator could select a specific IOCDS as part of a power on reset (POR).
The Michigan Terminal System (MTS) is one of the first time-sharing computer operating systems. [1] Created in 1967 at the University of Michigan for use on IBM S/360-67, S/370 and compatible mainframe computers, it was developed and used by a consortium of eight universities in the United States, Canada, and the United Kingdom over a period of 33 years (1967 to 1999).
