<h1 class="topictitle1">DFNLIN (Define Line) keyword</h1>
|
|
<div><p>Use this record-level keyword to draw a horizontal or a vertical
|
|
line.</p>
|
|
<div class="section"><p>A horizontal line is drawn at the bottom of the character spaces
|
|
from left to right. A vertical line is drawn on the right edge of the character
|
|
spaces from top to bottom.</p>
|
|
<p>The format of this keyword is:</p>
|
|
<pre>DFNLIN(direction start_line start_position length)</pre>
|
|
<p>The direction parameter specifies whether the defined line
|
|
is horizontal or vertical. The value specified must be one of the following
|
|
ones:</p>
|
|
<ul><li>*VRT</li>
|
|
<li>*HRZ</li>
|
|
</ul>
|
|
<p>The start line parameter specifies the line number, from the top of
|
|
the page, where the defined line starts. The possible values are 1 through
|
|
255, but the value specified must not exceed the page length value specified
|
|
on the PAGESIZE parameter of the Create Printer File (CRTPRTF) command.</p>
|
|
<p>The
|
|
start position parameter specifies the position number, from the left margin
|
|
of the page, where the defined line starts. The possible values are 1 through
|
|
378, but the value specified should not exceed the page width value specified
|
|
on the PAGESIZE parameter of the CRTPRTF command.</p>
|
|
<p>The length parameter
|
|
specifies the length in number of lines when the defined line is vertical
|
|
or in number of characters when the defined line is horizontal.</p>
|
|
<p>The
|
|
length specified must be greater than zero. For a vertical line, the sum of
|
|
the length and the value of the start line parameter cannot exceed 255. Although
|
|
255 is the maximum value of this sum, valid values must not exceed the page
|
|
length specified on the PAGESIZE parameter of the CRTPRTF command.</p>
|
|
<p>For
|
|
a horizontal line, the sum of the length and the value of the start position
|
|
parameter cannot exceed 378. Although 378 is the maximum value of this sum,
|
|
valid values must not exceed the page width specified on the PAGESIZE parameter
|
|
of the CRTPRTF command.</p>
|
|
<p>All parameters are required.</p>
|
|
<p>A warning
|
|
message will be issued at create time if:</p>
|
|
<ul><li>The start line value specified is larger than the page length value specified
|
|
on the PAGESIZE parameter of the CRTPRTF command.</li>
|
|
<li>The start position value specified is larger than the page width value
|
|
specified on the PAGESIZE parameter of the CRTPRTF command.</li>
|
|
<li>The sum of the length and the start line value for a vertical line is
|
|
larger than the page length specified on the PAGESIZE parameter of the CRTPRTF
|
|
command.</li>
|
|
<li>The sum of the length and the start position value for a horizontal line
|
|
is larger than the page width specified on the PAGESIZE parameter of the CRTPRTF
|
|
command.</li>
|
|
</ul>
|
|
<p>The DFNLIN keyword can be specified more than once at the record level.</p>
|
|
<p>Option
|
|
indicators are allowed for this keyword.</p>
|
|
<p>The DFNLIN keyword cannot be
|
|
specified on a record that also contains keywords that are valid only on IPDS™ printers
|
|
(such as COLOR, BARCODE, and LPI). If DFNLIN is specified with any of those
|
|
keywords, a severe error (severity 30) message will be issued.</p>
|
|
<p>If the
|
|
DFNLIN keyword is specified when a printer file is created with DEVTYPE(*IPDS),
|
|
a warning (severity 10) message is issued but the keyword is not ignored at
|
|
creation time. However, the keyword is ignored and a message is issued when
|
|
the printer file is used.</p>
|
|
<p>If the DFNLIN keyword is specified with a
|
|
printer file created with DEVTYPE(*AFPDS), the keyword is ignored and a warning
|
|
message is issued.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
|
the DFNLIN keyword on the DDS coding form.</p>

<p>The output of RECORD1 format is a box.</p>
|

<p>The output
|
|
of the first DFNLIN keyword is a horizontal line. The line is drawn to the
|
|
right from the twelfth character position on the fourth line for a length
|
|
of 20 characters.</p>
|
|
<p>The output of the second DFNLIN keyword is a vertical
|
|
line. The line is drawn down from the twelfth character position on the fifth
|
|
line for a length of 6 lines.</p>
|
|
<p>The output of the third DFNLIN keyword
|
|
is a horizontal line. The line is drawn to the right from the ending point
|
|
of the second line (10 = 4 + 6) for a length of 20 characters.</p>
|
|
<p>The output
|
|
of the fourth DFNLIN keyword is a vertical line. The line is drawn down from
|
|
the ending point of the first line (32 = 12 + 20) for a length of 6 lines.</p>
