A Double-Byte Character Set supports languages that have more characters
than can be represented by 8 bits (such as Korean Hangeul and Japanese
kanji). REXX has a full range of DBCS functions and handling techniques.
These include:
- Symbol and string handling capabilities with DBCS characters
- An option that allows DBCS characters in symbols, comments, and
literal strings.
- An option that allows data strings to contain DBCS characters.
- A number of functions that specifically support the processing
of DBCS character strings
- Defined DBCS enhancements to current instructions and functions.
Note: The use of DBCS does not affect the meaning of the
built-in functions as described in
Functions. This explains
how the characters in a result are obtained from the characters of
the arguments by such actions as selecting, concatenating, and padding.
The appendix describes how the resulting characters are represented
as bytes. This internal representation is not usually seen if the
results are printed. It may be seen if the results are displayed
on certain terminals.
