<h1 class="topictitle1">Copy spooled and nonspooled DBCS files</h1>
<div><p>You can copy both spooled and nonspooled DBCS files.</p>
<div class="section"><h4 class="sectiontitle">Copy spooled files</h4><p>Copy spooled files that have
double-byte data by using the Copy Spooled File (CPYSPLF) command. However,
the database file to which the file is being copied must have been created
with the IGCDTA(*YES) value specified.</p>
<p>When copying spooled files to
a database file that contains double-byte data, an extra column is reserved
for the shift-out character. This shift-out character is placed between the
control information for the record and the user data. The following table
shows the shift-out character column number, based on the value specified
for the Control character (CTLCHAR) keyword:</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="border" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e28">CTLCHAR value</th>
<th valign="top" id="d0e30">Column for shift-out character</th>

</div>
</div>
<div class="section"><h4 class="sectiontitle">Copy nonspooled DBCS files</h4><p>You can use the Copy
File (CPYF) command to copy double-byte data from one file to another.</p>
<p>When you copy data from a double-byte database
file to an alphanumeric database file, specify one of the following parameters
on the CPYF command:</p>
<ul><li>If both files are source files or if both files are database files, you
can specify either the FMTOPT(*MAP) parameter or the FMTOPT(*NOCHK) parameter.</li>
<li>If one file is a source file and the other file is a database file, specify
the FMT(*CVTSRC) parameter.</li>
</ul>
<p>When you copy DBCS files to alphanumeric files, the system sends you
an informational message describing the difference in file types.</p>
<p>Either
the FMTOPT(*MAP) or FMTOPT(*NOCHK) option of the copy file function must be
specified for copies from a physical or logical file to a physical file when
there are fields with the same name in the from-file and to-file, but the
data type for fields is as shown in the following table:</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="border" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e75">From-file field data type</th>
<th valign="top" id="d0e77">To-file field data type</th>
</tr>

</div>
<p>When you use FMTOPT(*MAP) on the CPYF command to copy data to a
DBCS-only field or DBCS-graphic field, the corresponding field in the from-file
must not be:</p>
<ul><li>Less than a 2-byte character field</li>
<li>An odd-byte-length character field</li>
<li>An odd-byte-length DBCS-open field</li>
</ul>
<p>If you attempt to copy with one of these specified in the from-field,
an error message is sent.</p>
<p>When you copy double-byte data from one database
file to another with the FMTOPT(*MAP) parameter specified, double-byte data
is copied correctly. The system performs correct padding and truncation of
double-byte data to ensure data integrity.</p>
<p>When using the CPYF command
with FMTOPT(*MAP) to copy a DBCS-open field to a graphic field, a conversion
error occurs if the DBCS-open field contains any SBCS data (including blanks).</p>
