<h1 class="topictitle1">DFT (Default) keyword in printer files</h1>
|
|
<div><p>Use the DFT keyword to specify a constant value for constant fields.</p>
|
|
<div class="section"><p>The format of the keyword is:</p>
|
|
<pre>DFT('value')
|
|
'value'
|
|
DFT(X'hexadecimal-value')
|
|
X'hexadecimal-value'</pre>
|
|
<p>Constant values can be:</p>
|
|
<ul><li>A character value, in which each character prints as you specify it. The
|
|
number of characters is equal to the printed length of the field. (Within
|
|
the value, two adjacent single quotation marks are printed as one.) See <a href="#rzakdmstptdft__rzakddft">example 1</a>.</li>
|
|
<li>A hexadecimal value, in which two characters identify a code point in
|
|
the character set. These characters print in this field (define alternate
|
|
characters using DFNCHR). The printed length is half the number of characters
|
|
you specify between single quotation marks. You must specify the TRNSPY keyword
|
|
if you specify a hexadecimal value for DFT. See <a href="#rzakdmstptdft__constantdft">example
|
|
2</a>.</li>
|
|
</ul>
|
|
<p>You can specify DFT implicitly by omitting DFT and the parentheses
|
|
(this is true for both character and hexadecimal values). Specify the value
|
|
within single quotation marks. For hexadecimal values, you must also precede
|
|
the value with an X.</p>
|
|
<p>The EDTCDE and EDTWRD keywords cannot be specified
|
|
with the DFT keyword.</p>
|
|
<p>Option indicators are not valid for this keyword.
|
|
However, they can be used to condition the constant field with which this
|
|
keyword is specified, specifying the last option indicator on the same line
|
|
as the field location.</p>

<p>The constant field for which DFT is specified <strong>1</strong> appears

on line 58, position 4. The character defined for hexadecimal 7C prints in

this field. DFNCHR <strong>2</strong>, specified at the record level for this example,
|
|
defines hexadecimal 7C as a copyright mark.</p>
|

<div class="p">Here are

some equivalent ways to specify the value as defined in this example <strong>3</strong>:
