<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>

the FMT(*CVTSRC) parameter.</li>

|
<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>

|
<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>
