Repeats the statements between the Do and the Loop statement while the condition is True or until the condition becomes True.
  Do {While | Until} condition = True
  ' Do While: The statement block is repeated as long as the condition is true
  ' Do Until: The statement block is repeated as long as the condition is false
     statements
     [Exit Do]

  ' Loop While: The statement block repeats as long as the condition is true
  ' Loop Until: The statement block repeats until the condition is true
  Loop {While | Until} condition = True
The Do...Loop statement executes a loop as long as, or until, a certain condition is True. The condition for exiting the loop must be entered following either the Do or the Loop statement. The above examples are valid combinations.
condition: A comparison, numeric or Basic expression, that evaluates to either True or False.
statements: Statements that you want to repeat while or until a condition is True.
Use the Exit Do statement to unconditionally end the loop. You can add this statement anywhere in a Do...Loop statement. You can also define an exit condition using the If...Then structure as follows:
  Do...
     statements
     If condition = True Then Exit Do
     statements
  Loop...

        Do
            MsgBox sFile
            sFile = Dir$
        Loop Until sFile = ""
