Do...Loop Statement
Repeats a block of statements while a condition is True or until a condition becomes True.
Do
[statements] [ExitLoop]
[statements]
Loop {While | Until} condition
Remarks
The ExitLoop can only be used within a Do...Loop control structure to provide an alternate way to exit a Do...Loop. Any number of ExitLoop statements may be placed anywhere in the Do...Loop. Often used with the evaluation of some condition (for example, If...Then), ExitLoop transfers control to the statement immediately following the Loop.
When used within nested Do...Loop statements, ExitLoop transfers control to the loop that is nested one level above the loop where it occurs.
Example
Dim lop as integer
lop = 1
DO
answer = "1"
LOAD
answer = "0"
LOAD
lop= lop + 1
if lop = 3 then
exitloop
endif
answer = "1"
LOAD
LOOP UNTIL lop = 8
