how would you program negative numbers in the early DOS days?


well zero is 0,0 adding or subtracting youd get an off set of 1 but then what about screen buffers?
i have one that needs to be offset by 400 so sould i minus 400 or -399?

actually wron i totaly diprooved my theory… after 5 mins of posting i realized that you start at zero you add 5 your at 4 you subtract 5 your at -4… but its a lot of thinking nonetheless… some one give me a good read lol
