    COBOL standards have repeatedly suffered from delays: COBOL-85 arrived five years later than hoped, [193] COBOL 2002 was five years late, [3] and COBOL 2014 was six years late. [101] [194] To combat delays, the standard committee allowed the creation of optional addenda which would add features more quickly than by waiting for the next standard ...

    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.

    In computing, a signed overpunch is a coding scheme which stores the sign of a number by changing (usually) the last digit. It is used in character data on IBM mainframes by languages such as COBOL, PL/I, and RPG. [1]

  8. User-defined function - Wikipedia

    en.wikipedia.org/wiki/User-defined_function

    In the COBOL programming language, a user-defined function is an entity that is defined by the user by specifying a FUNCTION-ID paragraph. A user-defined function must return a value by specifying the RETURNING phrase of the procedure division header and they are invoked using the function-identifier syntax.

  9. 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.
