Exit

Parameters: NONE

Returns: NONE

Exit terminates the current loop and continues program execution after that loops closing statement.

FACTS:

* Also See: ExitFor, ExitWhile, ExitRepeat, or ExitDo, to explicitly define the loop you want to exit.

* Exit can only exit the current loop. So if you've inside a couple of nested loops (of the same type) you might find Goto an easy option to exit out of them.

Mini Tutorial #1:

; Start of a DO/LOOP loop
  Do

     Print "Here we go..."

   ; Exit this DO/LOOP and continue running the code
   ; beyond the LOOP statement.  Thus skipping following
   ; print statement
     Exit

     Print "... but we don't go here."
  Loop

  Print "Loop Exited"

; Display the Screen and wait for the user to press a key
  Sync
  WaitKey

This example would output.

  Here we go...
  Loop Exited

Mini Tutorial #2:

; start of programs main DO/LOOP
  Do

   ; clear the screen
     Cls 0

   ; Start of For NExt Loop
     For X=0 To 1000
      ; Check if the loop counter variable X
      ; is greater than 100, if so, EXIT
      ; the FOR/NEXT loop
        If X> 10
           Print "Exiting For/Next"
           Exit
        EndIf
        Print "X="+Str$(X)
     Next

   ; show the screen to the user
     Sync

   ; loop back to the do statement to keep program running
  Loop

This example would output.

  X=0
  X=1
  X=2
  X=3
  X=4
  X=5
  X=6
  X=7
  X=8
  X=9
  X=10
  Exiting For/Next
