the object.</p>

<div class="section"> <p>The number of key parameters should be limited to the number

of parameters needed to uniquely define the object to be changed.</p>
|

|
|
<p>To
|
||
|
|
ensure a key parameter is coded correctly in the command definition source,
|
||
|
|
do the following: </p>
|
||
|
|
<ul><li>Specify KEYPARM(*YES) on the PARM statement in the command definition
|
||
|
|
source.</li>
|
||
|
|
<li>Define all parameters that specify KEYPARM(*YES) before all parameters
|
||
|
|
that specify KEYPARM(*NO). <div class="note"><span class="notetitle">Note:</span> If a PARM statement specifies KEYPARM(*YES)
|
||
|
|
after a PARM statement that specifies KEYPARM(*NO), the parameter is not treated
|
||
|
|
as a key parameter and a warning message is issued.</div>
|
||
|
|
</li>
|
||
|
|
<li>Do not specify a MAX value greater than one in the PARM statement.</li>
|
||
|
|
<li>Do not specify a MAX value greater than one for ELEM statements associated
|
||
|
|
with key parameters.</li>
|
||
|
|
<li>Do not specify *PMTRQS or a prompt control statement for the PMTCTL keyword
|
||
|
|
on the PARM statement.</li>
|
||
|
|
<li>Place key parameters in the command definition source in the same order
|
||
|
|
you want them to appear when prompted.</li>
