DBCS Processing Functions
The functions that support DBCS mixed strings are described. These functions handle mixed strings, regardless of the OPTIONS mode.
Note: When used with DBCS functions, length is
always measured in bytes (as opposed to
LENGTH(string),
which is measured in characters).Counting option
In EBCDIC, when specified in the functions, the counting option can control whether the SO and SI are considered present when determining the length. Y specifies count SO and SI in mixed strings. N, the default, specifies do not count the SO and SI.
