Using subroutines TO SQUARE REPEAT 4 [FORWARD 100 RIGHT 90] END TO SQUARE1 REPEAT 4 [FORWARD 200 RIGHT 90] END TO OCTAGON REPEAT 8 [FORWARD 100 RIGHT 45] END TO OCTAGON1 REPEAT 8 [FORWARD 200 RIGHT 45] END

Using variables TO SQUARE :size REPEAT 4 [FORWARD :size RIGHT 90] END TO OCTAGON :size REPEAT 8 [FORWARD :size RIGHT 90] END

The same shape multiple times close together TO MOVINGSQUARE :size REPEAT 4 [FORWARD :size RIGHT 90] FORWARD :size + 10 REPEAT 4 [FORWARD :size RIGHT 90] … END

Using the FOR keyword TO MOVINGSQUARE :size :repeat REPEAT 4 [FORWARD :size RIGHT 90] FOR [i 0 :repeat 1] [~ RIGHT 90 FORWARD :size + :i REPEAT 4 [FORWARD :size RIGHT 90] ] END
