<h1 class="topictitle1">Access command definitions</h1>
|
||
|
|
<div><p>Access to the command definitions occurs during program creation
|
||
|
|
time and at command run time. </p>
|
||
|
|
<div class="section"> <p>To allow for syntax checking, the command must exist during the
|
||
|
|
creation of a program that uses it. If it is qualified at creation time, the
|
||
|
|
command needs to exist in the library referred to during creation, and in
|
||
|
|
the same library when processed. If it is not library-qualified, it must be
|
||
|
|
in some library on the library list during creation time and at run time.</p>
|
||
|
|
<p>The
|
||
|
|
command name should be qualified in the program: </p>
|
||
|
|
<ul><li>When the command's definition will not be accessible through the library
|
||
|
|
list while the program is running.</li>
|
||
|
|
<li>When multiple command definitions exist with the same name if expecting
|
||
|
|
a specific instance of the command at run time.</li>
|
||
|
|
</ul>
|
||
|
|
<p>The name of the command must be the same when the program runs as
|
||
|
|
when the system created it. An error occurs if the command name changes after
|
||
|
|
creating a program that refers to that command. This is because the program
|
||
|
|
cannot find the command when it runs. However, if a default changes for a
|
||
|
|
parameter on a command, the new default is used when that command runs.</p>
