Instructs the assembler to accept double-byte character set data,
and to support graphic (G-type) constants and self-defining terms. The
assembler recognizes
X'0E' and X'0F' in character strings enclosed by single
quotation marks, and treats them as Shift-Out and Shift-In control
characters for delimiting DBCS data.
NODBCS
Specifies that the assembler does not recognize X'0E'
and X'0F' as double-byte character set data delimiters,
and does not support graphic (G-type) constants and self-defining terms.
