Tabs 160 spaces from the top lefthand CHAR-

ACTERSPACEon the screen, which is the same as

4 rows beneath the clear command. . . this starts

your PRINT message on the 6th line down on the

screen.

Hold down the

B8 key and press the key

marked

11II at the same time. If you do this

inside quotation marks, a "reversed E" will ap-

pear. This sets the color to everything PRINTed

from then on to WHITE.

This is a simple PRINT statement.

This sets the color back to light blue when the

PRINT statement ends. Holding down

m and

II at the same time inside quotation marks

causes a "reversed diamond symbol" to appear.

Sets the variable P equal to 192. This number 192

is the pointer you must use, in this case to "point"

sprite 0 to the memory locations that begin at lo-

cation 12288. Changing this pointer to the loca-

tions of the other two sprite shapes is the secret of

using one sprite to create an animation that is

actually three different shapes.

Steps the movement of your sprite 3 X positions at

a time (to provide fast movement) from position 0

to position 347.
