<h1 class="topictitle1">Control language</h1>
|
|
<div><p>Control language (CL) is the primary interface to the operating
|
|
system. CL can be used at the same time by users at different workstations,
|
|
in batch and interactive jobs and in CL programs and procedures.</p>
|
|
<p>A single control language statement is called a command. Commands can be
|
|
entered in the following ways: </p>
|
|
<ul><li>Individually from a workstation.</li>
|
|
<li>As part of batch jobs.</li>
|
|
<li>As source statements to create a CL program or procedure.</li>
|
|
</ul>
|
|
<p>Commands can be entered individually from any command line or the Command
|
|
Entry display.</p>
|
|
<p>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.</p>
