```
exit repeat
exit functionName
exit messageName
exit to HyperCard
```
The exit keyword interrupts the current flow of control.
Exit repeat sends control to the end of a repeat structure, ending execution of the loop regardless of the state of the controlling conditions.
The exit functionName and exit messageName forms stop the current message or function handler. Control returns to any pending statements from another handler, if any.
Exit to HyperCard terminates all running or pending handlers and cancels all pending messages.
Using exit to leave a function handler sets the value of the function to empty.
