The turtle speaks

Page 10

The turtle is good at drawing. But he can also speak. However, you must tell him what to say. This is how you tell the turtle to say "hello":

PRINT [hello]

If you want him to say:

"All mimsy were the borogoves,
And the mome raths outgrabe"

then you can write:

PRINT [All mimsy were the borogoves,]
PRINT [And the mome raths outgrabe]

(I don't know what that means either!) You can also try this:

; make the turtle say hello 10 times
REPEAT 10 [PRINT [Hello!]]

That was not so difficult. Was it?

These are all the words we know now. PRINT is new:

Logo word What it means
FD 100 Walk forward 100 steps
BK 100 Walk backward 100 steps
LT 90 Turn left (good for drawing squares)
RT 90 Turn right (good for drawing squares)
LT 120 Turn left (good for drawing triangles)
RT 120 Turn right (good for drawing triangles)
CS Remove everything you have drawn
HOME Move back to the starting point (and draw a line)
PU Lift the pen so you won't draw when you walk
PD Put the pen towards the screen again
REPEAT 10 [       ] Repeat what's in the box 10 times
SETPC 4 Change the pen to pen number 4
TO ... END Remember the word after TO in the future
; Don't listen to me now
PRINT [I'm a turtle!] Say "I'm a turtle!"

These are the words we have taught the turtle. They are the same as on the last page:
