and press RETURN. The Commodore 128 displays a sprite grid
on the 40 column screen, ln addition, the computer displays the
prompt:
SPRITE NUMBER ?
Enter a number between 1 and 8. The computer displays the
corresponding sprite in the upper right corner of the screen. From
now on, we will refer to the sprite grid as the work area. The work
area has the dimensions of 24 characters wide by 21 characters
tall. Each character position within the work area corresponds to
1 pixel within the sprite, since a sprite is 24 pixels wide by 21
pixels tall. While within the work area in SPRDEF mode, you have
several editing commands available to you. Here’s a summary of
the commands:
