Editing Job Control Language (section)

{{For|Other (non-IBM) Job Control Languages|Job control (computing)}}

Other mainframe [[batch processing|batch]] systems had some form of job control language, whether called that<ref name="stallings"/> or not; their syntax was completely different from IBM versions, but they usually provided similar capabilities.  Such a language would have control cards with a special indicator, such as an initial dollar sign with <code>$JOB</code> being the first such card, interspersed with cards containing program code, data to be run, and so on.<ref name="stallings">{{cite book | title=Computer Organization and Architecture: Designing for Performance | first=William | last=Stallings | publisher=Prentice-Hall | location=Upper Saddle River, New Jersey | year=1996 | edition=Fourth | page=228 | isbn=0-13-359985-X}}</ref>

[[Interactive computing|Interactive]] systems 
include "[[command language]]s"&mdash;command files (such as PCDOS ".bat" files) can be run non-interactively, but these usually do not provide as robust an environment for running unattended jobs as JCL.  On some computer systems the job control language and the interactive command language may be different.  For example, [[Time Sharing Option|TSO]] on z/OS systems uses [[CLIST]] or [[Rexx]] as command languages along with JCL for batch work.  On other systems these may be the same.
