A single break command can be used to stop code after the break from executing. Can also be used to exit a state early. Also used inside switch blocks to close case statements.
Inside while loops, a break transfers control to the beginning of the loop where the condition for continuing the iteration is checked. This is in contrast to most imperative programming languages, where a break inside a loop transfers control to just after the end of the loop body (thus "breaking" it). For example, in CON, the snippet
See also return.
Examples
setvar j 0 whilevarn j 3 { addvar j 1 userquote 500 break // while is inner: "continue" userquote 400 }
makes quote 500 be displayed three times in total and quote 400 not a single time.
