Condition: A comparison, numeric or string expression, that evaluates either True or False.
Statement block: Statements that you want to repeat while or until the condition is 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 following examples are valid combinations:

Do While condition = Truestatement block
LoopThe statement block between the Do While and the Loop statements is repeated so long as the condition is true.
Do Until condition = Truestatement block
