Control blocks is one of the nine categories of Scratch blocks. They are color-coded amber, and are used to control scripts under certain conditions.

In Scratch 1.4 and earlier, this category also included the blocks that are now Events Blocks.

There are currently 11 Control blocks: 1 Hat block, 5 C blocks, 3 Stack blocks and 2 Cap blocks.

repeat for () seconds {
} :: control loop
