|
<div><p><span class="keyword">i5/OS™</span> uses control
|
||
|
|
language (CL) commands to interpret instructions from users. Learn the basic
|
||
|
|
rules for using CL, and how to get detailed help for any CL command.</p>
|
||
|
|
<p><span class="keyword">i5/OS</span> CL provides a
|
||
|
|
powerful and flexible means of entering commands on the iSeries™ server.
|
||
|
|
You can use CL to control most of the iSeries functions by entering them from
|
||
|
|
the character-based interface, by including them in programs, or by sending
|
||
|
|
commands in iSeries Navigator.
|
||
|
|
While the iSeries menu
|
||
|
|
system and CL commands might be unfamiliar at first, they follow an easy-to-use
|
||
|
|
syntax, and <span class="keyword">i5/OS</span> includes
|
||
|
|
many features to help you use them successfully.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">CL command syntax</h4><p>CL commands consist of a verb,
|
||
|
|
an <span class="keyword">i5/OS</span> object, and sometimes
|
||
|
|
an adjective; for example, WRKACTJOB:</p>
|
||
|
|
|
||
|
|
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="void" border="0" rules="none"><thead align="left"><tr><th valign="top" id="d0e61">Verb</th>
|
||
|
|
<th valign="top" id="d0e63">Adjective</th>
|
||
|
|
<th valign="top" id="d0e65">Object</th>
|
||
|
|
</tr>
|
||
|
|
</thead>
|
||
|
|
<tbody><tr><td valign="top" headers="d0e61 ">WRK</td>
|
||
|
|
<td valign="top" headers="d0e63 ">ACT</td>
|
||
|
|
<td valign="top" headers="d0e65 ">JOB</td>
|
||
|
|
</tr>
|
||
|
|
<tr><td valign="top" headers="d0e61 ">Work</td>
|
||
|
|
<td valign="top" headers="d0e63 ">Active</td>
|
||
|
|
<td valign="top" headers="d0e65 ">Job</td>
|
||
|
|
</tr>
|
||
|
|
</tbody>
|
||
|
|
</table>
|
||
|
|
</div>
|
||
|
|
<p>One of the important features of CL syntax is that it is consistent.
|
||
|
|
For example, regardless of the object or command you want to work with, using
|
||
|
|
the verb WRK in the command starts a menu that allows you to perform the available
|
||
|
|
actions on the specified object.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Enter CL commands</h4><p>You can enter CL commands from iSeries Navigator
|
||
|
|
by selecting <span class="uicontrol">Run a command</span> from the task pad. Alternatively,
|
||
|
|
you can enter CL commands from any command line and most displays on the iSeries character-based
|
||
|
|
interface.</p>
|
||
|
|
<p>Every command has a set of required and optional parameters.
|
||
|
|
For example, Create Library (CRTLIB) requires, at a minimum, that you specify
|
||
|
|
the name of the library you need to create. The syntax for more complex CL
|
||
|
|
commands is: <samp class="codeph">command_name</samp> <em>parameter</em> <em>(value)</em>.
|
||
|
|
For example, CRTLIB LIB (FRED) enters the verb <dfn class="term">create</dfn>, on the
|
||
|
|
object type <dfn class="term">library</dfn>, and specifies that the required parameter
|
||
|
|
LIB, the library name, must have the value <dfn class="term">FRED</dfn>. This command
|
||
|
|
causes <span class="keyword">i5/OS</span> to create
|
||
|
|
a library called FRED.</p>
|
||
|
|
<p>If you are not familiar with the parameters associated
|
||
|
|
with a CL command, you can enter the command with the parameters you already
|
||
|
|
know, place the cursor on the command, and press F4 (Prompt). <span class="keyword">i5/OS</span> then
|
||
|
|
displays the available options for the command. Entering a command without
|
||
|
|
any parameters also causes the system to prompt you for any required fields,
|
||
|
|
making field-level help available. For example, entering CRTLIB causes <span class="keyword">i5/OS</span> to show the following display:</p>
|
||
|
|
<br /><img src="rzal2001.gif" alt="list of required fileds for CRTLIB. Entering '?' brings up filed help" /><br /><p>Entering a <span class="uicontrol">?</span> in
|
||
|
|
any field brings up detailed help for that parameter.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Get help with CL commands</h4><p><span class="keyword">i5/OS</span> provides
|
||
|
|
several methods for helping users access and enter CL commands. The Command
|
||
|
|
Entry program provides a useful interface and additional help. You can start
|
||
|
|
this program by entering CALL QCMD from a command line. The CL finder in
|
||
|
|
the information center can also help you find a specific command. Most importantly,
|
||
|
|
remember that entering a command without any parameters, or pressing F4 (Prompt)
|
||
|
|
while your cursor is over the command, displays a menu with detailed help
|
||
|
|
for all associated parameters.</p>
