Comparing national and other character-string operands
You can compare the character value of a national literal or class national data item
with the character value of any of the following other character-string operands: alphabetic,
alphanumeric, alphanumeric-edited, UTF-8, DBCS, or
numeric-edited of USAGE DISPLAY.
About this task
These operands are treated as if they were moved to an elementary national data item. The characters are converted to national (UTF-16) representation, and the comparison proceeds with two national character operands.
