A single break command can be used to stop code after the break from executing. Its primary use is inside switch blocks to close case statements, but it can also be used to exit a state early.
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).
In versions of eduke32 starting from 24th August 2023, the "break" command will report a warning if used inside a loop. Use continue or exit instead for clarity.
See also return and terminate.
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.
