[edit] Quick graphical examples
When UCBLogo first starts up the screen is fully taken up by the interactive text input area. When you issue your first graphic instruction the screen will automatically split into a graphic and text input area. Here's some simple example instruction to try, case is insensitive:
HELP "FORWARD
Now you know how to get help on a command:
FORWARD 100 RIGHT 90 FORWARD 100 RIGHT 90 FORWARD 100 RIGHT 90 FORWARD 100 RIGHT 90
Or for less typing use a repeat loop:
REPEAT 4 [FORWARD 100 RIGHT 90]
Or make it a procedure:
TO square REPEAT 4 [FORWARD 100 RIGHT 90] END square
Re-edit a procedure you've created with:
EDIT "square
To wipe the graphics screen type:
CLEARSCREEN
