DAS: Decimal Adjust after Subtraction:- This instruction converts the result of subtraction operation of 2 packed BCD numbers to a valid BCD number. The subtraction operation has to be only in the AL. If the lower nibble of AL is higher than the value 9, this instruction will subtract 06 from lower nibble of the AL. If the output of subtraction operation sets the carry flag or if the upper nibble is higher than value 9, it subtracts 60H from the AL. This instruction modifies the CF, AF, PF, SF and ZF flags. The OF is not defined after DAS instruction. The instance is following:
