<h1 class="topictitle1">SUBDEV (Subdevice) keyword for ICF files</h1>
|
||
|
|
<div><p>Use this file- or record-level keyword to allow your program to
|
||
|
|
request a specific subdevice (for example, a printer) to which transmitted
|
||
|
|
data should be directed.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>SUBDEV(*DC1 | *DC2 | *DC3 | *DC4)</pre>
|
||
|
|
</div>
|
||
|
|
<p>The
|
||
|
|
SUBDEV keyword is ignored at run time when EOS, DETACH, RSPCONFIRM, or RQSWRT
|
||
|
|
is in effect. These keywords must have option indicators when they apply
|
||
|
|
to a record for which the SUBDEV keyword applies. If an EOS, DETACH, RSPCONFIRM,
|
||
|
|
or RQSWRT keyword with no option indicator applies to a record for which SUBDEV
|
||
|
|
applies, an error message is issued and the SUBDEV keyword is ignored at creation
|
||
|
|
time.</p>
|
||
|
|
<p>You can specify only one parameter value for each SUBDEV keyword.</p>
|
||
|
|
<p>You
|
||
|
|
can specify this keyword more than once in the file; however, you cannot specify
|
||
|
|
the same parameter value at the file level and again at the record-level.
|
||
|
|
This is true even if you specify option indicators each time. For example,
|
||
|
|
if you specify SUBDEV(*DC1) at the file level, you cannot specify SUBDEV(*DC1)
|
||
|
|
anywhere else in the file.</p>
|
||
|
|
<p>If you specify the SUBDEV keyword at both
|
||
|
|
the file level and the record level, and your program selects the one at the
|
||
|
|
file level, the record-level keyword(s) have no effect even if also selected.</p>
|
||
|
|
<p>You
|
||
|
|
can specify the SUBDEV keyword a maximum of four times for each record format.
|
||
|
|
If you specify the SUBDEV keyword more than once, you must specify option
|
||
|
|
indicators each time, and you can specify each keyword value only once.</p>
|
||
|
|
<p>The <span class="keyword">i5/OS™</span> operating
|
||
|
|
system sends a device selection character as follows. The meaning of the
|
||
|
|
device selection character is set by the remote system or device. </p>
