 		 #120591 - XBY(ADDRESS) - incomplete?
Responding to: ???'s previous message
Rishab Bucha said:
i had a command XBY(ADDRESS) same as out in 8085

Well, it can't be quite the same, can it?

An OUT instruction would require both an address and a data value to write to that address!

How can XBY(ADDRESS) perform any output if it doesn't specify what data to send?!
