WORDPOS
In EBCDIC:
WORDPOS('<.B.C> abc','<.A. .B.C> abc') -> 2
WORDPOS('<.A.B>','<.A.B. .A.B><. .B.C. .A.B>',3) -> 4

DBCS Processing Functions
This section describes the functions that support DBCS mixed strings. 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 counting SO and SI within mixed strings. N
specifies not to count the SO and SI, and is the default.
Function Descriptions
The following are the DBCS functions and their descriptions.
DBADJUST
DBADJUST(string )
,operation
In EBCDIC, adjusts all contiguous SI and SO (or SO and SI) characters in string based on the operation
specified. The following are valid operations. Only the capitalized and highlighted letter is needed; all
characters following it are ignored.
Blank changes contiguous characters to blanks (X'4040').
Remove
removes contiguous characters, and is the default.
Here are some EBCDIC examples:
DBADJUST('<.A><.B>a<>b','B') -> '<.A. .B>a b'
DBADJUST('<.A><.B>a<>b','R') -> '<.A.B>ab'
DBADJUST('<><.A.B>','B') -> '<. .A.B>'
DBBRACKET
DBBRACKET(string)
In EBCDIC, adds SO and SI brackets to a DBCS-only string. If string is not a BCS-only string, a SYNTAX
error results. That is, the input string must be an even number of bytes in length and each byte must be a
valid DBCS value.
Here are some EBCDIC examples:
DBBRACKET('.A.B') -> '<.A.B>'
DBBRACKET('abc') -> SYNTAX error
DBBRACKET('<.A.B>') -> SYNTAX error
