SQUARE with VARIABLE

1. To make a spiral, we need to increase the length each time it repeats.
2. To do this we will make a variable called “length” that we can control.
3. Before the square code, type: make “length 30
4. Replace your fd 40  by fd :length
5. Try your code – try changing the number after make “length to make different sized squares.

SPIRAL

1.  Start with make “length 30
2. Inside the repeat brackets put the following line:
3. make “length :length +10
4. NOTE the difference between “len and :len (“len is for changing it; :len is for using/calculating with it)
5. Increase the number of repeats
