|
||
|
|
<div><p>You use FMTOPT(*MAP) to convert universal coded character set (UCS-2)
|
||
|
|
graphic fields.</p>
|
||
|
|
<p>Using FMTOPT(*MAP) to copy <em>to</em> a UCS-2 graphic field converts the
|
||
|
|
data in the from-field CCSID to the CCSID of the UCS-2 graphic
|
||
|
|
to-field. If the length after conversion is less than the length of the UCS-2
|
||
|
|
graphic to-field, the field is padded . If the length after conversion is
|
||
|
|
greater than the length of the UCS-2 graphic to-field, the field is truncated.</p>
|
||
|
|
<p>Using FMTOPT(*MAP) to copy <em>from</em> a UCS-2 graphic field converts the
|
||
|
|
data from the CCSID of the UCS-2 graphic field to the CCSID of the to-field.
|
||
|
|
If the length after conversion is less than the length of the to-field, the
|
||
|
|
field is padded. If the length after conversion is greater than the length
|
||
|
|
of the to-field, the field is truncated. Shift-out and shift-in characters
|
||
|
|
are added around double-byte data except in DBCS-graphic and UCS-2 graphic
|
||
|
|
fields.</p>
|
||
|
|
<p>UCS-2 conversion possibilities also include variable length fields. Generally,
|
||
|
|
the result length of a variable length to-field will be the minimum of the
|
||
|
|
from-field converted length and the maximum length of the to-field.</p>
|
||
|
|
<p>The CCSID conversions created when copying from or to a UCS-2 graphic field
|
||
|
|
might cause the byte length of the data to be different after the conversion.
|
||
|
|
The maximum length of the to-field is used to determine if all of the converted
|
||
|
|
data will fit in the to-field.</p>
|
||
|
|
<p>When copying from a UCS-2 graphic field to a character field, or to a DBCS-either
|
||
|
|
field where the first byte is already converted to a valid SBCS character
|
||
|
|
(not a shift-out <span>X'0E'</span>), any remaining characters that cannot be
|
||
|
|
converted to SBCS (actual double-byte data in the UCS-2 field) will have a
|
||
|
|
single-byte substitution character set in its place.</p>
|
||
|
|
<p>When copying from a UCS-2 graphic field to a DBCS-only, DBCS-graphic field,
|
||
|
|
or to a DBCS-either field where the first byte is already converted to a DBCS
|
||
|
|
shift-out (<span>X'0E'</span>), any remaining characters that cannot be converted
|
||
|
|
to DBCS will have a double-byte substitution character set in its place.</p>
|
||
|
|
<p>To be successful when using FMTOPT(*MAP) to convert from or to UCS-2 data,
|
||
|
|
the resulting converted data for the to-field must conform to the to-field
|
||
|
|
type. Otherwise, conversion errors will occur and the to-field will be set
|
||
|
|
to its default value.</p>
