language, operating system (JCL)
IBM's supremely
rude script language, used to control the execution of programs
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
ignorance of JCL.
