    en.wikipedia.org/wiki/Support_programs_for_OS/...

    IGYCRCTL is a common example of a compiler; it is the compiler for the current IBM Enterprise COBOL for z/OS product. (There have been several previous IBM COBOL compilers over the years, with different names, although users might provide an alias COBOL for the current version.) There are many other compilers for various other programming ...

  3. IBM COBOL - Wikipedia

    en.wikipedia.org/wiki/IBM_COBOL

    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.

    en.wikipedia.org/wiki/COBOL

    COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and ...

    The Burroughs B2500 through Burroughs B4900 was a series of mainframe computers developed and manufactured by Burroughs Corporation in Pasadena, California, United States, from 1966 to 1991. They were aimed at the business world with an instruction set optimized for the COBOL programming language.

    A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...

  8. Job Control Language - Wikipedia

    en.wikipedia.org/wiki/Job_Control_Language

    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.

  9. Burroughs Large Systems - Wikipedia

    en.wikipedia.org/wiki/Burroughs_Large_Systems

    The Burroughs Large Systems Group produced a family of large 48-bit mainframes using stack machine instruction sets with dense syllables. [NB 1] The first machine in the family was the B5000 in 1961, which was optimized for compiling ALGOL 60 programs extremely well, using single-pass compilers.
