<div><p>The length of a field containing bracketed-DBCS data can range
|
|||
|
|
from 4 through 32 766 bytes (4 through 32 740 bytes if the field
|
|||
|
|
is variable length). The length of a DBCS-graphic field can range from 1 through
|
|||
|
|
16 383 characters (1 through 16 370 characters if the field is variable
|
|||
|
|
length).</p>
|
|||
|
|
<div class="section"><div class="p">When determining the length of a field containing
|
|||
|
|
DBCS data, consider the following rules: <ul><li>Each DBCS character is 2 bytes long.</li>
|
|||
|
|
<li>For DBCS-graphic fields, the length of the field is specified in the number
|
|||
|
|
of DBCS characters.</li>
|
|||
|
|
<li>Include both shift-control characters in the length of the field for fields
|
|||
|
|
with a data type of J, E, or O. Together, these characters are 2 bytes long.</li>
|
|||
|
|
<li>Fields specified with the J or E data type must have an even
|
|||
|
|
length.</li>

characters, 1 shift-in character, and 1 shift-out character, has 8 bytes of

data: <pre>(3 characters x 2 bytes) + (shift-out + shift-in) = 8</pre>
