<h4 id="rzalufcfcd">First-character forms-control data considerations</h4>
|
||
|
|
<p>For program-described printer files, you can also specify the print control
|
||
|
|
information in the data itself. You can do this by including an American
|
||
|
|
National Standard first-character forms-control code in position 1 of each
|
||
|
|
data record in the printer file. (You cannot use first-character forms control
|
||
|
|
and DDS on the same file.)</p>
|
||
|
|
<p>For information about the machine data, see <a href="../rzau6/rzau6machine.htm">Machine Code Carriage Control Characters</a> in the Advanced Function Presentation
|
||
|
|
topic collection.</p>
|
||
|
|
<p>To include the print control information in the data, you specify one of
|
||
|
|
the following American National Standard first-character forms-control codes
|
||
|
|
in the first position of each data record:</p>

<p>Any other character in position 1 of a record defaults to a blank (the
|
||
|
|
American National Standard code for spacing one line). If this occurs, the
|
||
|
|
notify message CPF4916 is sent to the high-level language program once per
|
||
|
|
file.</p>
|
||
|
|
<p>When you use first-character forms-control data for a printer file, the
|
||
|
|
print control information created by the high-level language compiler is ignored.
|
||
|
|
The character in position 1 of the record is used as the print control character
|
||
|
|
for that record.</p>
|
||
|
|
<p>To create a program-described printer file that uses first-character forms-control
|
||
|
|
data, specify the CTLCHAR parameter and, optionally, the CHLVAL parameter
|
||
|
|
on the Create Printer File (CRTPRTF) command. CTLCHAR(*FCFC) specifies that
|
||
|
|
the first character in every record is an American National Standard forms-control
|
||
|
|
code.</p>
|
||
|
|
<p>The CHLVAL parameter allows you to associate a specific skip-to line number
|
||
|
|
with an American National Standard channel identifier. For example, if you
|
||
|
|
specify CHLVAL(2 20), channel identifier 2 is allocated with line number 20;
|
||
|
|
therefore, if you place the forms-control 2 in the first position of a record,
|
||
|
|
the printer skips to line 20 before printing the line. </p>
|
||
|

<a name="wq138"></a>
|
||
|
|
<div class="notetitle" id="wq138">Note:</div>
|
||
|
|
<div class="notebody">If
|
||
|
|
the printer stops at a particular line number and the next record processed
|
||
|
|
has a channel value forms-control number that is the same value as the line
|
||
|
|
number the printer is on, the printer advances to that value (line number)
|
||
|
|
on the next page. In the example in the paragraph above, if the printer had
|
||
|
|
been on line 20 already, the printer would then have advanced to line 20 of
|
||
|
|
the next page.</div>
|
||
|
|
<p>There is one exception to this method of printer advancement.</p>
|
||
|
|
<p>If the printer is positioned at the top of the page (line 1) and the channel
|
||
|
|
value forms-control value is line 1, the printer does not advance to a new
|
||
|
|
page.</p>
|
||
|
|
<p>Each control identifier can be specified only once on the parameter. If
|
||
|
|
no line number is defined for a channel identifier and that channel identifier
|
||
|
|
is encountered in the data, the printer takes the default of spacing one line
|
||
|
|
before printing.</p>
|
||
|
|
<p>In the following example, a file, PRTFCFC, that uses first-character forms-control
|
||
|
|
data is created: </p>
|
||
|
|
<pre class="xmp">CRTPRTF FILE(QGPL/PRTFCFC) OUTQ(PRINT) CTLCHAR(*FCFC) +
|
||
|
|
CHLVAL((1 1) (2 10) (12 60))</pre>
|
||
|
|
<p>The printer output is spooled to the output queue PRINT. Channel identifier
|
||
|
|
1 is associated with line 1, channel identifier 2 is associated with line
|
||
|
|
10, and channel identifier 12 is associated with line 60.</p>
