Introduction

Branches are control flow functions which rule whether following statements or blocks shall be executed or not.

• if() ... else: Conditional branches
• once() ... else: Following statement or block is executed once only
• switch() ... case(): Branches to statements or blocks where the condition is met. Only 1 case where the expression matches will be executed.
• check() ... case(): Branches to statements or blocks where the condition is met. All cases where the expression matches will be executed.

See also the exception functions throw() / catch() for skipping the remaining code inbetween.
