CL Programming


Control Language

Control language (CL) is the primary interface to the operating system and can be used at the same time by users at different work stations. A single control language statement is called a command. Commands can be entered in the following ways:

Commands can be entered individually from any command line or the Command Entry display.

To simplify the use of CL, all the commands use a consistent syntax. In addition, the operating system provides prompting support for all commands, default values for most command parameters, and validity checking to ensure that a command is entered correctly before the function is performed. Thus, CL provides a single, flexible interface to many different system functions that can be used by different system users.
