The work area has the dimensions of 24 characters wide by 21 char
acters tall. Each character position within the work area corres
ponds 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 on the following page: * |

mode:
1. Clear the work area by pressing the shift and CLR/HOME keys at j j
the same time.
2. If you want a multicolor sprite, press the M key and an additional
cursor appears next to the original one. Two cursors appear | f
since multicolor mode actually turns on two pixels for every one
in standard sprite mode. This is why multicolor mode is only half
the horizontal resolution of standard high-res mode. ! I
