Description

Repeats a block of statements while a condition is True or until a condition becomes True.

Syntax

Do [{While | Until} condition]
    [statements]
    [Exit Do]
    [statements]
Loop

Or, you can use this syntax:

Do
    [statements]
    [Exit Do]
    [statements]
Loop [{While | Until} condition]

The Do...Loop statement syntax has these parts:

Part	Description
condition	Numeric or string expression that is True or False. If condition is Null, condition is treated as False.
statements	One or more statements that are repeated while or until condition is True.

Remarks

The Exit Do can only be used within a Do...Loop control structure to provide an alternate way to exit a Do...Loop. Any number of Exit Do statements may be placed anywhere in the Do...Loop. Often used with the evaluation of some condition (for example, If...Then), Exit Do transfers control to the statement immediately following the Loop.

When used within nested Do...Loop statements, Exit Do transfers control to the loop that is nested one level above the loop where it occurs.

The following examples illustrate use of the Do...Loop statement:

Do Until DefResp = vbNo
  MyNum = Int (6 * Rnd + 1)	' Generate a random integer between 1 and 6.
  DefResp = MsgBox (MyNum & " Do you want another number?", vbYesNo)
Loop

Dim Check, Counter
Check = True: Counter = 0		' Initialize variables.
Do					' Outer loop.
  Do While Counter < 20		' Inner loop.
    Counter = Counter + 1		' Increment Counter.
    If Counter = 10 Then		' If condition is True...
      Check = False			' set value of flag to False.
      Exit Do			' Exit inner loop.
    End If
  Loop
Loop Until Check = False		' Exit outer loop immediately.
