From The Jargon File (version 4.4.7, 29 Dec 2003) [jargon]:
JCL
/J?C?L/, n.
1. IBM's supremely {rude} Job Control Language. JCL is the script language
used to control the execution of programs in IBM'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 memorizes 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.
2. A comparative for any very {rude} software that a hacker is expected to
use. ?That's as bad as JCL.? As with {COBOL}, JCL is often used as an
archetype of ugliness even by those who haven't experienced it. See also
{IBM}, {fear and loathing}.
A (poorly documented, naturally) shell simulating JCL syntax is available
at the Retrocomputing Museum http://www.catb.org/retro/.
