Description
EXIT terminates the execution of a block of code in a DO...LOOP, FOR...NEXT, FOR EACH...NEXT, FUNCTION, or SUB. When used to exit a loop, either DO...LOOP, FOR...NEXT, or FOR EACH...NEXT, execution continues with the first statement after the loop; if the loop is nested inside another loop, control is transferred to the loop outside the loop where the EXIT is encountered. When used to exit a FUNCTION or SUB procedure, execution continues with the first statement after the statement which called the procedure.
Example
REM EXIT Example 'EXIT terminates loops and procedures DIM i FOR i = 1 to 10 IF i > 1 THEN EXIT FOR END IF PRINT "Attempting to do nothing" DoNothing NEXT PRINT "Done" SUB DoNothing EXIT SUB PRINT "This statement is never executed" END SUB
Output
Atempting to do nothing Done
