RE: Wrapping

["Gary McCallister" <mccallis@xxxx>]

Thanks! That should get him going again.

A turtle cannot draw in a text box. Wish it could.
But I still think that a turtle could constantly check its x
coordinate and if it exceeds a certain number, then it would jump
to a predesignated negative x coordinate and move 20 or 30 pixels
lower in its y coordinate to start a new line of morse code text.

to new_line
if xcor > 270 [setx -270 sety ycor - 40]
end

Without bothering with the morse code shapes, I tested the
new_line procedure above in this sample "type" procedure (with a
button set to "many times" and it works, moving from line to line
as it stamps random shapes:

to type
seth 90
setsh 1 + random 50
stamp
fd 40
wait 1
new_line
end
