<h1 class="topictitle1">Retrieve system values</h1>
|
||
|
|
<div><p>A system value contains control information for the operation of
|
||
|
|
certain parts of the system. </p>
|
||
|
|
<div class="section"> <p>IBM<sup>®</sup> supplies
|
||
|
|
several types of system values. For example, QDATE and QTIME are date and
|
||
|
|
time system values, which you set when i5/OS™ is started.</p>
|
||
|
|
<p>You can bring system
|
||
|
|
values into your procedure and manipulate them as variables using the <span class="cmdname">Retrieve
|
||
|
|
System Value (RTVSYSVAL)</span> command: </p>
|
||
|
|
<pre>RTVSYSVAL SYSVAL(system-value-name) RTNVAR(CL-variable-name)</pre>
|
||
|
|
<p>The RTNVAR parameter specifies the name of the variable in
|
||
|
|
your CL procedure that is to receive the value of the system value.</p>
|
||
|
|
<p>The
|
||
|
|
type of the variable must match the type of the system value. For character
|
||
|
|
and logical system values, the length of the CL variable must equal the length
|
||
|
|
of the value. For decimal values, the length of the variable must be greater
|
||
|
|
than or equal to the length of the system value.</p>

<li class="ulchildlink"><strong><a href="svqtime.htm">Example: Retrieve QTIME system value</a></strong><br />
|
||
|
|
In this example, QTIME is received and moved to a variable, which is then compared with another variable.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="convd.htm">QDATE system value</a></strong><br />
|
||
|
|
In many applications, you may want to use the current date in your procedure by retrieving the system value QDATE and placing it in a variable. You may also want to change the format of that date for use in your procedure.</li>
