<h1 class="topictitle1">Command names</h1>
|
||
|
|
<div><p>The command name identifies the function that will be performed
|
||
|
|
by the program that is called when the command is run. Most command names
|
||
|
|
consist of a combination of a verb (or, action) followed by a noun or phrase
|
||
|
|
that identifies the receiver of the action (or object being acted on): (command
|
||
|
|
= verb + object acted on).</p>
|
||
|
|
<div class="section"><p>Abbreviated words, usually one to three letters, make up the command
|
||
|
|
name. This reduces the amount of typing that is required to enter the command. </p>
|
||
|
|
<p>For
|
||
|
|
example, you can create, delete, or display a library; so the verb abbreviations
|
||
|
|
CRT, DLT, and DSP are joined to the abbreviation for library, LIB. The result
|
||
|
|
is three commands that can operate on a library: <span class="cmdname">CRTLIB</span>, <span class="cmdname">DLTLIB</span>,
|
||
|
|
and <span class="cmdname">DSPLIB</span>. In another example, one of the CL commands
|
||
|
|
is the Send Message command. You would use the <span class="cmdname">Send Message (SNDMSG)</span> command
|
||
|
|
to send a message from a user to a message queue.</p>
|
||
|
|
<p>The conventions for
|
||
|
|
naming the combination verb and object commands are as follows:</p>
|
||
|
|
<ul><li>The primary convention (as just shown) is to use three letters from each
|
||
|
|
word in the descriptive command name to form the abbreviated command name
|
||
|
|
that is recognized by the system.</li>
|
||
|
|
<li>The secondary convention is to use single letters from the ending word
|
||
|
|
or words in the command title for the end of the command name, such as the
|
||
|
|
three single letters DLO on the <span class="cmdname">Delete Document Library Object (DLTDLO)</span> command.</li>
|
||
|
|
<li>An occasional convention is to use single letters in the middle of the
|
||
|
|
command name (usually between commonly used three-character verbs and objects),
|
||
|
|
such as the letters CL in the <span class="cmdname">Create CL Program (CRTCLPGM)</span> command.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Some command names consist of the verb only, such as the <span class="cmdname">Move
|
||
|
|
(MOV)</span> command, or an object only, such as the <span class="cmdname">Data (DATA)</span> command.
|
||
|
|
A few commands have an i5/OS™ command name, and can also be called using one
|
||
|
|
or more alternate names that may be familiar to users of systems other than
|
||
|
|
the i5/OS system.
|
||
|
|
An alternate name is known as an <strong>alias</strong>, such as the name CD is an
|
||
|
|
alias for the <span class="cmdname">Change Current Directory (CHGCURDIR)</span> command.</p>
