3.2.7 Binary–coded Decimal Instructions
Five instructions support operations on binary-coded decimal (BCD) numbers. The
arithmetic operations on packed BCD numbers are add decimal with extend (ABCD),
subtract decimal with extend (SBCD), and negate decimal with extend (NBCD). PACK and
UNPACK instructions aid in the conversion of byte encoded numeric data, such as ASCII or
EBCDIC strings, to BCD data and vice versa. Table 3–7 is a summary of the BCD
operations.
