 		 #149276 - if case 4 is a biblical catastrophe
Responding to: ???'s previous message
you are referring to the case you gave earlier, 0x07 is already BCD, why would it convert it?

from "the bible"

if the AC flag is one, six is added to the Accumulator

see case 4)

coming to think about it (0x07 is already BCD, why would it convert it?) I am flabbergasted, we may have found a case where "the bible" does not speak the truth. My book copy is dated -93 and I have NEVER found an error (till now?)

Anyhow, even if case 4 is a biblical catastrophe, we still have case 1) or 2) (the double negative)
