Job Control Language {script} language, used to control the execution of programs in IBM {OS/360}'s {batch} systems. JCL has a very {fascist} {syntax}, and some versions will, for example, {barf} if two spaces appear where it expects one. Most programmers confronted with JCL simply copy a working file (or {card deck}), changing the file names. Someone who actually understands and generates unique JCL is regarded with the mixed respect one gives to someone who memorises the phone book. It is reported that hackers at IBM itself sometimes sing "Who's the breeder of the crud that mangles you and me? I-B-M, J-C-L, M-o-u-s-e" to the tune of the "Mickey Mouse Club" theme to express their opinion of the beast. As with {COBOL}, JCL is often used as an archetype of ugliness even by those who haven't experienced it. However, no self-respecting {mainframe} {MVS} programmer would admit ignorance of JCL. See also {fear and loathing}. (1999-03-03) |
