Thank you, l see what you mean.
Earlier you or someone else said that storing to an odd RAM address (like
1501) is BAD, so is that why you might not want to do move.b 150, -(a7)
because b would be 1?
l can see how storing things to RAM addresses is a great thing, but how do you
know which ones to use?  How many are there?
