<h1 class="topictitle1">Key parameters and prompt override programs</h1>
|
||
|
|
<div><p>The prompt override program allows current values rather than defaults
|
||
|
|
to be displayed when a command is prompted. Key parameters are parameters,
|
||
|
|
such as the name of an object, that uniquely identify the object. </p>
|
||
|
|
<div class="section"> <p>If a prompt override program is defined for a command, you can
|
||
|
|
see the results of calling the prompt override program in the following two
|
||
|
|
ways:</p>
|
||
|
|
<ul><li>Type the name of the command without parameters on any command line and
|
||
|
|
press F4=Prompt. The next screen shows the key parameters for the command. <p>Complete
|
||
|
|
all fields shown and press the Enter key. The next screen shows all command
|
||
|
|
parameters, and the parameter fields that are not key parameter fields contain
|
||
|
|
current values rather than defaults (such as *SAME and *PRV).</p>
|
||
|
|
<p>For example,
|
||
|
|
if you type <samp class="codeph">CHGLIB</samp> on a command line and press F4=Prompt,
|
||
|
|
you see only the Library parameter. If you then type <samp class="codeph">*CURLIB</samp> and
|
||
|
|
press the Enter key, the current values for your current library are displayed.</p>
|
||
|
|
</li>
|
||
|
|
<li>Type the name of the command and the values for all key parameters on
|
||
|
|
any command line. Press F4=Prompt. The next screen shows all command parameters,
|
||
|
|
and the parameter fields that are not key parameter fields will contain current
|
||
|
|
values rather than defaults (such as *SAME and *PRV). <p>For example, if
|
||
|
|
you type <samp class="codeph">CHGLIB LIB(*CURLIB)</samp> on a command line and press
|
||
|
|
F4=Prompt, the current values for your current library are displayed.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>When F10=Additional parameters is pressed, any parameters defined
|
||
|
|
with PMTCTL(*PMTRQS) are displayed with current values.</p>
|
||
|
|
<p>To
|
||
|
|
exit the command prompt, press F3=Exit.</p>
