' RETURN.BS2 ' This program demonstrates a potential bug caused by allowing a program to ' "fall into" a subroutine. The program was intented to indicate that it ' is "Starting...", then "Executing Subroutine,", then "Returned..." from ' the subroutine and stop. Since we left out the END command (indicated in ' the comments), the program then falls into the subroutine, displays ' "Executing..." again and then RETURNs to the start of the program and ' runs continuously in an endless loop. ' {$STAMP BS2} Reset: DEBUG "Starting Program", CR ' show start-up Main: PAUSE 1000 GOSUB Demo_Sub ' call the subroutine PAUSE 1000 DEBUG "Returned from Subroutine", CR ' show that we're back PAUSE 1000 ' <-- Forgot to put END here Demo_Sub: DEBUG " Executing Subroutine", CR ' show subroutine activity RETURN
