Example for Do While

The above example Do while Loop will execute over and over until the variable “a” becomes greater than the value 7.
Sometimes, you may want to exit a While loop before the condition is False. We can exit a loop at any time by using the Exit Do Keyword.

Dim a As Integer
a=1
do while a<=6 MsgBox(“ Now A value is” & a) a=a+1 if a=3 then Exit Do End If Loop
