Part 2 involved more steps for each task and usually took a day or so to accomplish. The first 60 winners of Part 2 received monetary prizes in recognition of their achievement. Part 3 was more in depth, involving multiple programming challenges such as COBOL, REXX, JCL, etc. (depending on the questions set for the year's challenge). [5]
Use of IBM COBOL was so widespread that Capex Corporation, an independent software vendor, made a post-code generation phase object code optimizer for it. [3] The Capex Optimizer became a quite successful product. [4] Although the IBM COBOL Compiler Family web site [5] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
As it is an assembly language, BAL uses the native instruction set of the IBM mainframe architecture on which it runs, System/360, just as the successors to BAL use the native instruction sets of the IBM mainframe architectures on which they run, including System/360, System/370, System/370-XA, ESA/370, ESA/390, and z/Architecture.
It shared most of the code base [4] and some manuals [5] [6] with IBM's DOS/360. TOS went through 14 releases, and was discontinued [ 7 ] [ failed verification ] when disks such as the IBM 2311 and IBM 2314 became more affordable at the time of System/360, [ 8 ] [ failed verification ] whereas they had been an expensive luxury on the IBM 7090 .
International Business Machines (IBM) used to dominate the computer industry -- especially in the 1960s when mainframe computers were the only game in town. During the 1970s, that dominance gave ...
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 .
Model 204 is commonly used in government and military applications. [8] [9] [10]It was used commercially in the UK by Marks & Spencer. [citation needed] It was also used at the Ventura County Property Tax system in California, [11] the Harris County, Texas, Justice Information Management System, [12] and in the New York City Department of Education's Automate The Schools system.
