  2. 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.

    Source Program Maintenance Online II (with abbreviations such as SPM, SPM/OL, or SPMOL-II, and pronounced "S-P-M" or, informally, "Spimoli"), is an IBM software product of the late 1970s and early 1980s that provided an online environment for computer programmers working on IBM mainframe systems.

  4. PC-based IBM mainframe-compatible systems - Wikipedia

    en.wikipedia.org/wiki/PC-based_IBM_mainframe...

    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 programs using any computer that supports J2SE 1.6.0+ runtime.

  5. Computer programming in the punched card era - Wikipedia

    en.wikipedia.org/wiki/Computer_programming_in...

    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 ...

    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.

  7. Burroughs Medium Systems - Wikipedia

    en.wikipedia.org/wiki/Burroughs_Medium_Systems

    Portable COBOL programs did not use binary integers at all, so the B2500 did not either, not even for memory addresses. Memory was addressed down to the 4-bit digit in big-endian style, using 5-digit decimal addresses. Floating point numbers also used base 10 rather than some binary base, and had up to 100 mantissa digits.

  8. IDMS - Wikipedia

    A version for use on the Digital Equipment Corporation PDP-11 series of computers was sold to DEC and was marketed as DBMS-11. In 1976 the source code was licensed to ICL , who ported the software to run on their 2900 series mainframes, and subsequently also on the older 1900 range .

  9. LINC 4GL - Wikipedia

    Now LINC is known as Unisys Enterprise Application Environment (EAE) and builds applications by generating executable code (Cobol)for Unisys ClearPath systems, Dorado and Libra (formerly Burroughs A-Series & Sperry OS1100 mainframes), Microsoft Windows, and various Unix and Linux platforms. It will also generate GUI front-end clients in Java
