|
<div><p>You can use bracketed-DBCS character strings in DDS files for text-related
|
||
|
|
keywords, such as TEXT and COLHDG, and both bracketed and DBCS-graphic character
|
||
|
|
strings as parameters on the COMP, DFT, RANGE, and VALUES keywords.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Considerations for using DBCS character strings</h4><p>Consider
|
||
|
|
the following information when you use DBCS character strings:</p>
|
||
|
|
<ul><li>Do not specify DBCS character strings for those DDS keywords that are
|
||
|
|
dependent on data type, and for which you did not specify a DBCS data type
|
||
|
|
(data type O, J, E, or G).</li>
|
||
|
|
<li>When the source file is defined as DBCS, DDS scans all character strings
|
||
|
|
as DBCS character strings and considers all data between the shift-control
|
||
|
|
characters to be part of the character string. <p>Remember to include both
|
||
|
|
shift-control characters. If the shift-in character indicating the end of
|
||
|
|
the DBCS string is missing, the system considers the remainder of the record,
|
||
|
|
including the ending single quotation mark, to be part of the character string.</p>
|
||
|
|
</li>
|
||
|
|
<li>When the source file is alphanumeric, DDS does not check the character
|
||
|
|
string to make sure that you have included only DBCS characters between the
|
||
|
|
shift-control characters.</li>
|
||
|
|
<li>When the source file is alphanumeric, DDS identifies DBCS character strings
|
||
|
|
as alphanumeric literals.</li>
|
||
|
|
<li>You can refer to a field that contains a DBCS character string from another
|
||
|
|
file, using the reference function. DDS copies the attributes of the field
|
||
|
|
containing the DBCS character string (the referenced field) to the field you
|
||
|
|
are defining. If the file containing the referenced field is DBCS and the
|
||
|
|
file you are defining is alphanumeric, DDS does not check the character string
|
||
|
|
to make sure that it is a valid DBCS character string. If the file containing
|
||
|
|
the referenced field is alphanumeric and the file you are defining is DBCS,
|
||
|
|
DDS checks the character string to make sure that it is a valid
|
||
|
|
DBCS character string.</li>
