OS/400 (now known as IBM i) is the native operating system of the AS/400 platform and was the sole operating system supported on the original AS/400 hardware. Many of the advanced features associated with the AS/400 are implemented in the operating system as opposed to the underlying hardware, which changed significantly throughout the life of ...
It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008. [8] [9] It is an evolution of the System/38 CPF operating system, [5] with compatibility layers for System/36 SSP and AIX applications. [5]
The RPG programming language originally was created by IBM for their 1401 systems. IBM later produced implementations for the 7070/72/74 [4] [5] and System/360; [6] RPG II became the primary programming language for their midrange computer product line, (the System/3, System/32, System/34, System/38, System/36 and AS/400).
This is a list of operating systems. Computer operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap.
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 ...
[2] [3] [4] It provided a common interface among the disparate programming languages available to the AS/400 computer platform. ILE was an improvement on the two existing programming models available on OS/400 – the Original Program Model (OPM), which was used for traditional business programming languages such as RPG and COBOL; and the ...
In the System window, you will find information about your computer, including the operating system version. The information displayed will include the Windows edition, system type (32-bit or 64 ...
In the early days of IBM mainframes, computer software was free – bundled at no extra charge with computer hardware. The OS/360 operating system and application support software like CICS were "open" to IBM customers long before the open-source software initiative. Corporations like Standard Oil of Indiana (Amoco) made major contributions to ...
