<h5 id="rzaluovrprtfatt">Override file attributes</h5>
|
||
|
|
<p>The simplest form of overriding a file is to override some attributes of
|
||
|
|
the file. For example, assume that you create a printer file named OUTPUT
|
||
|
|
with these attributes:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Page size: 66 by 132</li>
|
||
|
|
<li>Lines per inch: 6</li>
|
||
|
|
<li>Copies of printed output: 2</li>
|
||
|
|
<li>Pages for file separators: 2</li>
|
||
|
|
<li>Overflow line number: 55</li></ul>
|
||
|
|
<p>The Create Printer File (CRTPRTF) command used to create this file looks
|
||
|
|
like this:</p>
|
||
|
|
<p></p>
|
||
|
|
<pre class="xmp">CRTPRTF FILE(QGPL/OUTPUT) SPOOL(*YES)
|
||
|
|
PAGESIZE(66 132) LPI(6)
|
||
|
|
COPIES(2) FILESEP(2) OVRFLW(55)</pre>
|
||
|
|
<p>The printer file named OUTPUT is specified in your application program
|
||
|
|
with an overflow line number of 58. However, before you run the application
|
||
|
|
program, you want to change the number of copies of printed output to 3 and
|
||
|
|
the overflow line to 60. The override command looks like this:</p>
|
||
|
|
<p></p>
|
||
|
|
<pre class="xmp">OVRPRTF FILE(OUTPUT) COPIES(3) OVRFLW(60)</pre>
|
||
|
|
<p>When you call the application program, three copies of the output are printed.</p>
|
||
|
|
<p>When the application program opens the file, the file overrides, program-specified
|
||
|
|
attributes, and file attributes are merged to form the open data path (ODP),
|
||
|
|
which is used to manage the file during the running of the program. File overrides
|
||
|
|
have precedence over program-specified attributes. Program-specified attributes
|
||
|
|
have precedence over file-specified attributes. In this example, when the
|
||
|
|
file is opened and output operations are performed, spooled output will be
|
||
|
|
produced with a page size of 66 by 132, six lines per inch, three copies,
|
||
|
|
two file separator pages, and overflow at 60 lines.</p>
