After the Loop

What happens to the blocks that are under a loop, not inside it? They're carried out once, when the loop ends, that is, after all its passes. The program

• Repeat 3 times
  • Move forward
• Turn left ↺

takes three steps forward and then turns left once.

So when you build, watch where you drop a block. When you drag a block to a loop, you'll see where it will go: inside the loop (into its mouth), or under it. If a block ends up in the wrong place, drag it again.

A program can have more than one loop, even one under another. Each loop has its own number of passes.
