String data types may now be associated with a character set. To assign a character set, append CHARSET “charset-name” when specifying a data type. The character set name must be enclosed in quotation marks. Examples: DEFINE MYVAR : ORACLE VARCHAR2(20) CHARSET “ISO8859-1” DEFINE CNAME : ODBC CHAR(10) ALLOW NULLS CHARSET “ANSI_X3.4-1968” When specifying both a CHARSET and ALLOW NULLS, the keywords may appear in either order. When operations with strings of differing character sets are performed, an automatic character set conversion is done using the CMAP function.
