Editing Job Control Language (section)

===z/OS===
For JES2 JECL statements start with <code>/*</code>, for JES3 they start with <code>//*</code>, except for remote &nbsp;<code>/*SIGNON</code>&nbsp; and &nbsp;<code>/*SIGNOFF</code>&nbsp; commands.  The commands for the two systems are completely different.

====JES2 JECL====
The following JES2 JECL statements are used in z/OS 1.2.0.<ref>{{cite web|last=IBM Corporation|title=Job Entry Subsystem 2 (JES2) Control Statements|url=http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2b510/1.1.2?SHELF=EZ2ZO103&DT=20010626133938&CASE=|work=z/OS V1R2.0 MVS JCL|access-date=February 25, 2013|archive-date=October 18, 2015|archive-url=https://web.archive.org/web/20151018201305/http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2b510/1.1.2?SHELF=EZ2ZO103&DT=20010626133938&CASE=|url-status=dead}}</ref>
