Rules at a Glance
Exit Do
Exits a Do...Loop statement. If the current Do...Loop is within a nested Do...Loop, execution continues with the next Loop statement wrapped around the current one. If, however, the Do...Loop is standalone, program execution continues with the first line of code after the Loop statement.
Exit For
Exits a For...Next loop. If the current For...Next is within a nested For...Next loop, execution continues with the next Next statement wrapped around the current one. If, however, the For...Next loop is stand-alone, program execution continues with the first line of code after the Next statement.
Exit Function
Exits the current function. Program execution is passed to the line following the call to the function.
Exit Property
Exits the current property procedure. Program execution is passed to the line following the call to the property.
Exit Sub
Exits the current sub procedure. Program execution is passed to the line following the call to the procedure.
