<h1 class="topictitle1">Constant fields in printer files</h1>
|
||
|
|
<div><p>Constant fields are unnamed fields (positions 19 through 28 must
|
||
|
|
be blank), or fields with a special name (*NONE) when POSITION (Position)
|
||
|
|
keyword is used in the record.</p>
|
||
|
|
<div class="p">The following rules apply when specifying a constant field: <ul><li>Positions 17 through 38 must be blank if you specify the location of the
|
||
|
|
field in positions 39 through 44.</li>
|
||
|
|
<li><img src="./delta.gif" alt="Start of change" />Positions 17, 18, and 29 through 44 must be blank if you
|
||
|
|
specify the POSITION keyword.<img src="./deltaend.gif" alt="End of change" /></li>
|
||
|
|
<li>The field can be conditioned using option indicators (positions 7 through
|
||
|
|
16).</li>
|
||
|
|
<li><img src="./delta.gif" alt="Start of change" />You can specify a constant field in a record format that
|
||
|
|
has a BOX, ENDPAGE, GDF, LINE, OVERLAY, or PAGSEG keyword specified on the
|
||
|
|
record, only if you have specified a POSITION keyword on the constant field.<img src="./deltaend.gif" alt="End of change" /></li>
|
||
|
|
<li>The constant itself is defined in positions 45 through 80 using one of
|
||
|
|
the following constant field keywords: <ul><li>Explicit DFT keyword (specify the value within apostrophes with the DFT
|
||
|
|
keyword)</li>
|
||
|
|
<li>Implicit DFT keyword (specify the value within apostrophes without the
|
||
|
|
DFT keyword)</li>
|
||
|
|
<li>DATE keyword (specify no value)</li>
|
||
|
|
<li>TIME keyword (specify no value)</li>
|
||
|
|
<li>PAGNBR keyword (specify no value)</li>
|
||
|
|
<li>MSGCON keyword (specify the message description, the message file, the
|
||
|
|
library name, and the length of the message description)</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>The EDTCDE or the EDTWRD keyword can be specified for constant fields
|
||
|
|
only when DATE, TIME, or PAGNBR keywords are also specified.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>When specifying a location (positions 39 through 44) for constant fields,
|
||
|
|
you can specify the fields in any order if you use line numbers. If you do
|
||
|
|
not use line numbers, you must specify the fields in the order in which they
|
||
|
|
are to appear on the printed page.</p>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />When you specify the POSITION keyword with a constant field,
|
||
|
|
the special name *NONE signifies the start of the field in the DDS source.
|
||
|
|
Therefore, you must specify the POSITION keyword or any other keyword associated
|
||
|
|
with the constant field, either on the same line as the constant
|
||
|
|
field keyword or on a subsequent line.<img src="./deltaend.gif" alt="End of change" /></p>
