Comparing DBCS literals

Comparisons of DBCS literals are based on the compile-time locale. Therefore, do not use DBCS literals within a statement that expresses an implied relational condition between two DBCS literals (such as VALUE G'literal-1' THRU G'literal-2') unless the intended runtime locale is the same as the compile-time locale.
