DCOR A
Instruction
DCOR A
This instruction when used following an ADC (add with carry) or SUBC
(subtract with carry) instruction will decimal correct the result from the
binary addition or subtraction. Note that the ADC instruction must be
preceded with an ADD A, #066 (add hexadecimal 66) instruction for the
decimal addition correction. This instruction assumes that the two oper-
ands are in BCD (Binary Coded Decimal) format and produces the result
in the same BCD format. The Carry and Half Carry flags remain un-
changed.
