- People who use Logo with very young children often set up a simple procedure
- that allows the child to "drive" the turtle with single keystrokes. For
- example:
-
- to instant
- make "char readchar
- if :char = "F [fd 10]
- if :char = "B [bk 10]
- if :char = "L [lt 15]
- if :char = "R [rt 15]
- if :char = "U [penup]
- if :char = "D [pendown]
- instant
- end
-
- This version uses the letters of the alphabet as mnemonics for the Logo
- commands. For even younger children you might just use the bottom row
- of the keyboard and attach pictures to the keys. For slightly older
- children you could add a numeric repetition feature so that, for example,
- typing "6F" would move forward six times as far as just "F".
