RE: LOGO-L> Tessellation program

[RAY CATZEL <learn@computerpals.on.ca>]

Hi Michael,
Thanks for your help. As we say at ComputerPals "we learn by our mistakes" ;-)
I must admit that I have a tough time unraveling the logic of these recursive 
stacks. Has anyone found that this type of exercise is reasonable for kids of 
13 years?
Ray

No, the program is fine the way it is.  You switched the inputs.  Yehuda
suggested DO 16 3 as a first try.

DO 3 16 will eventually finish, but you'll have to wait a while... a LONG
while.
