Control Flow

Conditionals (If/Else)

Use if, elseif, and else to create decision branches. You can label the branches using then (label) or is (label).

Another example showing logic flow with explicit stop points:

You can verify values using equals or is syntax:

Switch / Case

The switch keyword allows for multi-branch decisions based on a value.

Loops (Repeat)

You can represent iterative processes using repeat loops. The loop continues until the condition in repeat while is met.

While Loops

Alternatively, use while loops where the condition is checked at the start.

Backward Actions in Loops

In a repeat loop, you can specify an action to be performed when looping back using the backward keyword.

Parallel Processing (Fork)

You can split the processing into parallel paths using fork, fork again, and end fork.

Use end merge instead of end fork to show a diamond merge shape.
