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.
There are actually two IBM JCLs: one for the operating system lineage that begins with DOS/360 and whose latest member is z/VSE; and the other for the lineage from OS/360 to z/OS. They share some basic syntax rules and a few basic concepts, but are otherwise very different.

Famous quotes containing the words job, control and/or language:
“The best job that was ever offered to me was to become a landlord in a brothel. In my opinion it’s the perfect milieu for an artist to work in.”
—William Faulkner (1897–1962)
“To try to control a nine-month-old’s clinginess by forcing him away is a mistake, because it counteracts a normal part of the child’s development. To think that the child is clinging to you because he is spoiled is nonsense. Clinginess is not a discipline issue, at least not in the sense of correcting a wrongdoing.”
—Lawrence Balter (20th century)
“Because language is the carrier of ideas, it is easy to believe that it should be very little else than such a carrier.”
—Louise Bogan (1897–1970)
