<div><p>When a display file object is created, it is tagged with the coded
|
|
character set identifier (CCSID) of the source file.</p>
|
|
<p> At compile time:</p>
|
|
<ul><li>All character data is read from the primary source file without any character
|
|
conversion being performed.</li>
|
|
<li>User message text (identified by the MSGCON keyword in DDS) remains the
|
|
same because it is assumed to be in the same CCSID as the primary source file.</li>
|
|
</ul>
|
|
<p>At run time, the constant data is converted based on the CHRID parameter
|
|
value used to create the display file object. This conversion is optional
|
|
and can occur only when the CHRID is set to *JOBCCSID or indirectly with CHRIDCTL.
|
|
This conversion is from the display file CCSID to the character identifier
|
|
(CHRID) of the device. The field-level keyword NOCCSID (no coded character
|
|
set identifier) allows the user to specify fields within the DDS that are
|
|
never to be converted.</p>
|
|
<div class="note"><span class="notetitle">Note:</span> To use data management support of CCSIDs, you must change source physical
|
|
files tagged with CCSID 65535 to a CCSID value that is associated with the
|
|
data.</div>

<div class="section" id="rbagsccsiddispfilesup__hdrcrtdspfchridparm"><a name="rbagsccsiddispfilesup__hdrcrtdspfchridparm"><!-- --></a><h4 class="sectiontitle">CHRID parameter on the Create Display
|
|
File command</h4><p>The CHRID parameter on the Create Display File (CRTDSPF)
|
|
command affects the conversion that occurs for the display file.</p>
|
|
<p>If
|
|
the *JOBCCSID value is specified on the CHRID parameter of the CRTDSPF command:</p>
|
|
<ul><li>Input characters are converted from the device character identifier (CHRID)
|
|
to the job CCSID.</li>
|
|
<li>Character data is sent to output-capable fields and converted from the
|
|
job CCSID to the device CHRID.</li>
|
|
<li>Constant text from the display file is converted from the CCSID of the
|
|
display file to the CHRID of the device.</li>
|
|
<li>All message files are tagged with a CCSID. Message text
|
|
is converted from the CCSID of the message file to the CHRID of the device.
|
|
When message files are tagged with a CCSID of 65535 (the system default),
|
|
it is assumed that the contents of the message files are already in the CHRID
|
|
of the device. To ensure that appropriate conversions occur, you can enable
|
|
CCSID support for messages.</li>
|
|
<li>Message replacement data is converted from the CCSID of the job, or from
|
|
the CCSID of the display file, to the CHRID of the device.</li>
|
|
<li>All status messages that are tagged with a CCSID other than 65535 are
|
|
converted to the CHRID of the device.</li>
|
|
<li>Message text for messages on a message line or in a message subfile (identified
|
|
by the ERRMSG, ERRMSGID, SFLMSG, and SFLMSGID keywords in DDS) is converted
|
|
from the message file CCSID to the device CHRID.</li>
|
|
</ul>
|
|
<p>If a specific value is specified for the CHRID parameter on the CRTDSPF
|
|
command, conversion is done between the CHRID specified on the CRTDSPF command
|
|
and the CHRID of the device. This conversion affects only fields defined with
|
|
the CHRID DDS keyword.</p>
|
|
<p>If the *DEVD value is specified on the CHRID
|
|
parameter of the CRTDSPF command, no conversion is performed. This is the
|
|
default setting.</p>

display files must be recompiled with a source file that has a CCSID value

<ul><li>The display file was originally compiled from a source file with a CCSID
