3. If ADC A,@HL is followed by an ADS A,#im, the ADC skips on carry to the instruction
a. 8 + 9 decimal addition (the contents of the address specified by the HL register is 9H):
b. 3 + 4 decimal addition (the contents of the address specified by the HL register is 4H):
immediately after the ADS. An ADS instruction immediately after the ADC does not skip even
if an overflow occurs. This function is useful for decimal adjustment operations.
