Do While Vs Do Until
 

Which of these should break out of a For Next Loop when x = 1?
I think I'm getting the same action either way. I want it to break when
x = 1 and skip the rest of the For/Next

x = 0
Do While x = 0
For i = 1 to 10
If val1 = val2 Then
x = 1
End If
Next i
Loop

x = 0
Do Until x = 1
For i = 1 to 10
If val1 = val2 Then
x = 1
End If
Next i
Loop

Do While Vs Do Until
 

marston,

You're understanding is correct. "Do While" & "Do Until" are both pre-tested
loops.

To get a post-tested loop use "Loop While" or "Loop Until"

examples:-

x = 0
Do
For i = 1 to 10
If val1 = val2 Then
x = 1
End If
Next i
LoopWhile x = 0

x = 0
Do
For i = 1 to 10
If val1 = val2 Then
x = 1
End If
Next i
Loop Until x = 1
======================

In your example you only need the following if you're just trying to exit
the for loop.

For i = 1 To 10
If val1 = val2 Then Exit For

Next i

JohnI

Do While Vs Do Until
 

is the do While doing anything or is that your attempt to break out of the
for next loop. If so, the do while or do unil or loop While or loop until
are all external to the for next loop and would have no effect (conditions
are checked at the Do or Loop line). If you want to break out of the for
next loop

for i = 1 to 10
if val1 = val2 then
exit for
end if
Next
