Specify the length of the field in these positions. The length
of a field containing bracketed-DBCS data can range from 4 through 32 763
bytes. The length of a DBCS-graphic field can range from 1 through 16 381
characters.
When determining the length of
a DBCS field, consider the following rules:
- Each DBCS character is 2 bytes long.
- For DBCS-graphic fields, the length of the field is specified in number
of DBCS characters.
- 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.
- Fields specified with the J or E data type or keyboard shift must have
an even length.
For example, a bracketed-DBCS field that contains up to 3 DBCS characters,
1 shift-in character, and 1 shift-out character, has 8 bytes of data:
(3 characters x 2 bytes) + (shift-out + shift-in) = 8
A DBCS-graphic field that contains up to 3 DBCS characters has 6 bytes
of data:
(3 characters x 2 bytes) = 6
