SVC is a two byte instruction with the hexadecimal operation code 0A; the second byte of the instruction, the SVC number, indicates the specific request. [2] The SVC number can be any value from 0 to 255, with the particular SVC number being up to the implementer of the operating system, e.g. on IBM's MVS, SVC 3 is used to terminate a program, while on the UNIVAC VS/9 and Fujitsu BS2000 ...
Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester , and was unrelated to the earlier and more widely used System Support Program operating system.
In 1976, IBM announced the IBM Series/1, the successor to the System/7. The Series/1 was the last in the line of special purpose sensor-based computers produced by IBM. The Laboratory Automation Group in SJRL acquired an early model of the Series/1 and by announcement time had ported LABS/7 to the Series/1.
It behaves like the editor, but does not allow saving the data. Edited files can also be saved under a different name, creating or replacing another file. ISPF provides the 'editor interface' which lets an application program display arbitrary data in the familiar editor panel. Thus many vendor packages use this familiar interface.
The Control Language (CL) is a scripting language originally created by IBM for the System/38 Control Program Facility [1] and later used in OS/400 (now known as IBM i). It bears a resemblance to the IBM Job Control Language and consists of a set of command objects (*CMD) used to invoke traditional programs or get help on what those programs do.
Since IBM hardware does I/O via the use of channels and channel programs, TPF would generate very small and efficient channel programs to do its I/O — all in the name of speed. Since the early days also placed a premium on the size of storage media — be it memory or disk, TPF applications evolved into doing very powerful things while using ...
The IBM Information Management System (IMS) is a joint hierarchical database and information management system that supports transaction processing. [1] Development began in 1966 to keep track of the bill of materials for the Saturn V rocket of the Apollo program, and the first version on the IBM System/360 Model 65 was completed in 1967 as ICS/DL/I and officially installed in August 1968.
Originally developed by IBM in 1959, the name Report Program Generator was descriptive of the purpose of the language: generation of reports from data files. [12] FOLDOC accredits Wilf Hey with work at IBM that resulted in the development of RPG. [13] FARGO (Fourteen-o-one Automatic Report Generation Operation) was the predecessor to RPG on the ...
