Commodore VIC-20 User Manual page 41

If you have trouble typing this example, flip back to the
section called "Getting Siarted" in Chapter One. You can't
hurt the VIC with anything you type, but you can get
confused by certain key combinations. If you accidentally
leave the $${ key engaged, for example, the resulting
display is difficult to decipher. If you make a mistake, hit
a few times and retype the entire line. The
new line will aulomaticaliy replace the old one. When you
have the two lines shown above on the screen, iype:
~U\ \H\ and press
As soon as you press that final
, you should
see hundreds of red and blue balls float by on your screen.
How? It's easy with the VIC. Look back at the example
above. See the two strange characters in the line that begins
with "1"? They were created when you held the f;r I key
and pressed the i£& and ^Sk. keys. The symbols that
appear are VIC's shorthand to tell it to make the first ball red
and the second one blue.
