<h1 class="topictitle1">Example: Retrieve data area ORDINFO</h1>
|
||
|
|
<div><p>This is an example of using a data area to track the status of
|
||
|
|
an order file.</p>
|
||
|
|
<div class="section"><p>Assume that you are using a data area named ORDINFO to track the
|
||
|
|
status of an order file. This data area is designed so that:</p>
|
||
|
|
<ul><li>Position 1 contains an O (open), a P (processing), or a C (complete).</li>
|
||
|
|
<li>Position 2 contains an I (in-stock) or an O (out-of-stock).</li>
|
||
|
|
<li>Positions 3 through 5 contain the initials of the order clerk.</li>
|
||
|
|
</ul>
|
||
|
|
<p>You would declare these fields in your procedure as follows:</p>
|
||
|
|
<pre>DCL VAR(&ORDSTAT) TYPE(*CHAR) LEN(1)
|
||
|
|
DCL VAR(&STOCKC) TYPE(*CHAR) LEN(1)
|
||
|
|
DCL VAR(&CLERK) TYPE(*CHAR) LEN(3)</pre>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>To retrieve the order status into &ORDSTAT, you would enter
|
||
|
|
the following: </p>
|
||
|
|
<pre>RTVDTAARA DTAARA(ORDINFO (1 1)) RTNVAR(&ORDSTAT)</pre>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>To retrieve the stock condition into &STOCK, you would enter
|
||
|
|
the following: </p>
|
||
|
|
<pre>RTVDTAARA DTAARA(ORDINFO (2 1)) RTNVAR(&STOCKC)</pre>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>To retrieve the clerk's initials into &CLERK, you would enter
|
||
|
|
the following:</p>
|
||
|
|
<pre>RTVDTAARA DTAARA(ORDINFO (3 3)) RTNVAR(&CLERK)</pre>
|
||
|
|
<p>Each use of the RTVDTAARA command requires the data area to
|
||
|
|
be accessed. If you are retrieving many subfields, it is more efficient to
|
||
|
|
retrieve the entire data area into a variable, then use the substring built-in
|
||
|
|
function to extract the subfields.</p>
