exit

#exit

##Syntax An exitStatement is one of:

(a) exit when trueFalseExpn (b) exit

##Description An exit statement is used to stop the execution of a loop or for statement. Form (a) is the most common. Here, the true/false expression is evaluated. If it is true, the loop is terminated and execution jumps down and continues just beyond end loop or end for. If it is false, the loop keeps on repeating. Form (b) always causes the loop to terminate. This form is almost always used inside another conditional statement such as if.

##Example Input names until finding Jones.

    var name : string
    loop
        get name
        exit when name = "Jones"
    end loop

##Details Exit statements must occur only inside loop or for statements. An exit takes you out of the closest surrounding loop or for. The only other ways to terminate a loop or for is by return (in a procedure or in the main program, in which case the entire procedure or main program is terminated) or by result (in a function, in which case the entire function is terminated and a result value must be supplied).

The form "exit when trueFalseExpn" is equivalent to "if trueFalseExpn then exit end if".
