<h4 id="rzaluacscp">Alternative character sets and code pages for printer output considerations</h4>
|
||
|
|
<p>Character sets are used with code pages to determine how each character
|
||
|
|
will appear in the printed output. Code pages consist of hexadecimal identifiers
|
||
|
|
(code points) assigned to character identifiers. For example, in code page
|
||
|
|
037 (EBCDIC), the letter e is assigned a code point of hex 85.</p>
|
||
|
|
<p>In multinational environments, data in one national graphics character
|
||
|
|
set might need to be printed on devices that support another national character
|
||
|
|
set. This is particularly true of characters with accents and other characters
|
||
|
|
with diacritical marks (such as ç, ñ, and ü). In this section, these
|
||
|
|
characters are called <span class="bold">extended alphabetics</span>.</p>
|
||
|
|
<p>For example, assume that a physical file on the system contains data in
|
||
|
|
the Basic French character set, and includes the character é. In the code
|
||
|
|
page used with the Basic French character set, this character is hex C0. The
|
||
|
|
data could have been entered on a display device that can handle the character
|
||
|
|
or could have been sent to the system from another system over a communications
|
||
|
|
line. When hex C0 is sent to a printer that is set up for the United States
|
||
|
|
Basic character set, the hex C0 is printed as {. Depending on the
|
||
|
|
printer and the hexadecimal value sent, the hexadecimal value could be an
|
||
|
|
unprintable character. The way the printer handles a specific hex code point
|
||
|
|
(for example, hex C0) depends on the current value of the CHRID parameter
|
||
|
|
in the printer file. You can specify the following parameter values for the
|
||
|
|
CHRID parameter: </p>
|
||
|
|
<ul>
|
||
|
|
<li>With an explicit value specified for the CHRID parameter, the printer
|
||
|
|
interprets the data as if the data were in the character set and code page
|
||
|
|
specified.</li>
|
||
|
|
<li>With CHRID(*SYSVAL) specified, the printer file takes the value specified
|
||
|
|
in the Graphic character set/Code page (QCHRID) system value when the output
|
||
|
|
is created.</li>
|
||
|
|
<li>With CHRID(*DEVD) specified, the printer uses the CHRID that was set with
|
||
|
|
the device control panel or that was specified when the printer device description
|
||
|
|
was created.</li>
|
||
|
|
<li>If you have specified CHRID(*JOBCCSID), the printer interprets the data
|
||
|
|
as if it were in the character set and code page that are associated with
|
||
|
|
the CCSID for the current job. For more information, see the <a href="../nls/rbagsglobalmain.htm">Globalization</a> topic.</li>
|
||
|
|
<li>With CHRID(*CHRIDCTL) specified, the printer file checks the CHRIDCTL
|
||
|
|
job definition attribute to determine whether to use *JOBCCSID or *DEVD on
|
||
|
|
the CHRID command parameter for the job.</li></ul>
|
||
|
|
<p>Not all printers can handle all CHRID parameter values. If a CHRID is
|
||
|
|
specified for a printer on which that CHRID is not supported, a message is
|
||
|
|
sent to the operator. See <a href="rzalurefchrid.htm#rzalurefchrid">CHRID values supported</a> for a description of
|
||
|
|
which printers support which extensions.</p>
|
||
|
|
<p>For program-described printer files, the value of the CHRID parameter determines
|
||
|
|
the code page and character set used to print the data. However, for externally
|
||
|
|
described printer files, the CHRID parameter is used only for fields that
|
||
|
|
also have the CHRID DDS keyword specified. Fields that do not have the CHRID
|
||
|
|
DDS keyword use the code page and character as if CHRID(*DEVD) had been specified
|
||
|
|
for the CHRID parameter on the printer file.</p>
|
||
|
|
<p>For printers with AFP(*YES) in the device description, the printer file
|
||
|
|
CDEPAG and FNTCHRSET parameters can be used to select a code page when the
|
||
|
|
printer file DEVTYPE parameter is *AFPDS. This applies to all IPDS™ printers except
|
||
|
|
4224, 4230, 4234, 4247, and 64xx.</p>
|
||
|
|
<p>The following figure shows how extended alphabetics are handled in printer
|
||
|
|
output:</p>

|

<div class="mmobj">

<img src="rs3h020.gif" alt="How extended alphabetics are handled in printer output" /></div></div>
|
||
|
|
<p>Assume that a record in a physical file contains a field with the value <tt class="xph">Renée</tt>. An application program reads the record from the physical
|
||
|
|
file, and writes a record containing the data to the spooled file. The output
|
||
|
|
field in the printer file that describes how <tt class="xph">Renée</tt> is to be
|
||
|
|
printed has the CHRID DDS keyword specified, indicating that the printer is
|
||
|
|
to interpret extended alphabetics. The graphic character set 288 and code
|
||
|
|
page 297 are specified for the interpretation in either the printer file or
|
||
|
|
the Graphic character set/Code page (QCHRID) system value. Code page 297
|
||
|
|
is used for French language.</p>
|
||
|
|
<p>When printing the data, the printer interprets hex C0 as specified in character
|
||
|
|
set 288 and code page 297. If character set 101 and code page 037 had been
|
||
|
|
selected, hex C0 (é) would have been printed as {.</p>
|
||
|
|
<p>One of the following CHRID values (graphic character set and code page)
|
||
|
|
must be specified to print fonts OCR-A and OCR-B on the IPDS printers: </p>
