The wildcard (%WLDCRD) function with a double-byte character set
(DBCS) field differs depending on whether the function is used
with a bracketed-DBCS field or a DBCS-graphic field.
When using the wildcard function with a bracketed-DBCS field, both single-byte
and double-byte wildcard values (asterisk and underline) are allowed. The
following special rules apply:
- A single-byte underline refers to one EBCDIC character; a double-byte
underline refers to one double-byte character.
- A single- or double-byte asterisk refers to any number of characters of
any type.
When using the wildcard function with a DBCS-graphic field, only double-byte
wildcard values (asterisk and underline) are allowed. The following special
rules apply:
- A double-byte underline refers to one double-byte character.
- A double-byte asterisk refers to any number of double-byte characters.
