Exit Do

Exit For

Exit Function

Exit Sub

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

// Exit Example
/* Break terminates loops */
/* Return terminates functions */

var i;
for(i = 1; i <= 10; ++i) {
  if(i > 1) {
    break;
  }
  NSB.Print("Attempting to do nothing");
  DoNothing();
}
NSB.Print(("Done") + "<br>");
function DoNothing() {
  return;
  NSB.Print("This statement is never executed");
}

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
