A86: 3 questions




It has been a whole day since I asked a question.  I have only three easy (I
think) questions this time.  The first is, how would I subtract a number from
another number.  I want to subtract my custom number into my number that makes
my sprite move around (b).

My second is if I were to put two sprites on the screen, would I just have to
do the fastsprite (putsprite) routine once for the two or twice?

Finally, what is the difference between ANDing, ORing, and XORing it to the
screen?
