<h1 class="topictitle1">IGCANKCNV (Alphanumeric-to-DBCS Conversion) keyword</h1>
|
||
|
|
<div><p>Use this field-level keyword to convert alphanumeric characters
|
||
|
|
to equivalent DBCS characters (Japanese only).</p>
|
||
|
|
<div class="section"><p>Each DBCS character is printed twice as wide as a printed alphanumeric
|
||
|
|
character.</p>
|
||
|
|
<p>This keyword has no parameters.</p>
|
||
|
|
<p>In addition to converting
|
||
|
|
alphanumeric characters, the system adds shift-control characters at the beginning
|
||
|
|
and end of converted character strings.</p>
|
||
|
|
<p>For example, the string</p>
|
||
|
|
<pre>ABCDE</pre>
|
||
|
|
<p>appears
|
||
|
|
as:</p>
|
||
|
|
<pre>0<sub>E</sub>A B C D E0<sub>F</sub></pre>
|
||
|
|
<p>after
|
||
|
|
it is converted. Note that shift-control characters were added to the string
|
||
|
|
(0<sub>E</sub>=shift-out, 0<sub>F</sub>=shift-in).</p>
|
||
|
|
<p>You may specify IGCANKCNV
|
||
|
|
for any named field.</p>
|
||
|
|
<p>Consider the following information
|
||
|
|
when using the IGCANKCNV keyword:</p>
|
||
|
|
<ul><li>The converted characters are printed according to the instructions specified
|
||
|
|
for printing DBCS data, such as expanded characters. For example, if you specify
|
||
|
|
the CHRSIZ(2) keyword, the characters converted by this keyword are doubled
|
||
|
|
in width.</li>
|
||
|
|
<li>This conversion does not affect other attributes of a file. For example,
|
||
|
|
if you specify this DDS keyword for a field that contains floating-point data,
|
||
|
|
the system leaves the data in the floating-point format. Only the printed
|
||
|
|
appearance of the field changes. Also, any other attributes defined for the
|
||
|
|
field are still applicable, even those that are not valid for DBCS fields.</li>
|
||
|
|
<li>The following DDS keywords are ignored when you specify the keyword IGCANKCNV:
|
||
|
|
<p>BLKFOLD<br />
|
||
|
|
CPI<br />
|
||
|
|
DFT<br />
|
||
|
|
IGCALTTYP</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<ul><li>The length of the printed string of characters expanded
|
||
|
|
by the IGCANKCNV function is at least two times the length of the original
|
||
|
|
string plus two positions for the shift-control characters. For example, after
|
||
|
|
a string of four Katakana characters is converted, its length is: <pre>10 ((4 characters by 2) + 2 shift-control characters)</pre>
|
||
|
|
<p>If you specify additional characters to be included in the string, such as
|
||
|
|
with the EDTWRD function, those characters also are expanded and the length
|
||
|
|
of the string changes accordingly. For example, suppose you specify
|
||
|
|
a 4-position field that also includes a dollar sign and a decimal point, such
|
||
|
|
as:</p>
|
||
|
|
<pre>$12.34</pre>
|
||
|
|
<p>After the field is
|
||
|
|
converted, the field length is 14. The four numbers in the field are expanded
|
||
|
|
(eight positions), the dollar sign and the decimal point are expanded (four
|
||
|
|
positions) and shift-control characters are added (two positions).</p>
|
||
|
|
</li>
|
||
|
|
<li>The field for which IGCANKCNV is specified should not contain any DBCS
|
||
|
|
data. The system does not support conversion of fields with both alphanumeric
|
||
|
|
and DBCS data. If a field with IGCANKCNV contains DBCS characters, the results
|
||
|
|
of the conversion cannot be predicted.</li>
|
||
|
|
<li>The field for which IGCANKCNV is specified cannot be a DBCS-graphic field
|
||
|
|
(a field with a data type of G).</li>
|
||
|
|
<li>The system replaces unprintable alphanumeric characters before it converts
|
||
|
|
them to equivalent DBCS characters as specified by the RPLUNPRT value on the
|
||
|
|
Create Printer File (CRTPRTF) command.</li>
|
||
|
|
<li>The output must be printed on a DBCS printer.</li>
|
||
|
|
<li>A warning message appears if IGCANKCNV is specified in a file created
|
||
|
|
with DEVTYPE(*IPDS).</li>
|
||
|
|
<li>For files created with DEVTYPE(*AFPDS), characters in the field specified
|
||
|
|
with IGCANKCNV are printed using the font identified by the IGCCDEFNT keyword.</li>
|
||
|
|
<li>IGCANKCNV cannot be specified on a record or on a field in a record if
|
||
|
|
that record also contains COLOR, BARCODE, or LPI.</li>
|
||
|
|
<li>Option indicators are not allowed with IGCANKCNV.</li>

||
|
|
