<div><p>When the IBM-host code scheme is used, the server uses shift-control
|
||
|
|
characters to identify the beginning and end of a string of double-byte characters.
|
||
|
|
The shift-out (SO) character, hex 0E, indicates the beginning of a double-byte
|
||
|
|
character string. The shift-in (SI) character, hex 0F, indicates the end
|
||
|
|
of a double-byte character string.</p>

||

<div class="section"> <div class="fignone" id="rbal3scdbc__rsl713"><a name="rbal3scdbc__rsl713"><!-- --></a><span class="figcap">Figure 1. Placement of shift-out and shift-in characters</span><br /><img src="rslh713.gif" alt="Graphic depicting the placement
of shift-out and shift-in characters" /><br /></div>
|
||
|
|
<p>Each shift-control character occupies the same amount of space as
|
||
|
|
one alphanumeric character. By contrast, double-byte characters occupy the
|
||
|
|
same amount of space as two alphanumeric characters.</p>
|
||
|
|
<p>When double-byte
|
||
|
|
characters are stored in a graphic field or a variable of graphic data type,
|
||
|
|
there is no need to use shift control characters to surround the double-byte
|
||
|
|
characters.</p>
