How to exit a while loop ?

[HansWerner]

How can I exit a while loop ?

I'm new to Labview and I've tried to do my first Labview programm.

I've taken an old example, a sieve for prime numbers. The old Erasthotenes sieve.

Similar to that (Visual Basic Example):

While (l <= k) and Teiler <= Math.Sqrt(i)

       Teiler = TeilerArray(l)

       If i Mod Teiler = 0 Then
            IstPrim = False
            Exit While
       End If
       l = l + 1
End While

So, how can I model that "Exit While" ?

Use the conditional terminal of the while loop to stop it, based on a logical conditional check for your code.

Where do I find this "conditional terminal" and what is it called in German ?

Is it "Haltepunkt" in the context menu of the while loop ?

How do I use the "conditional teminal" ?

I use the german version.

Pl see the attached snapshot.

Sorry, I dont know German.

This is not an exit statement.

See below.

As it seems to be only the for loop supports an exit statement.

"Conditional terminal" in the context menu.

Hi Hans,

it is an exit statement. If you connect the correct value to it, then the loop stops.

You can use a case structure to don't run other code if a special "stop event" occur.

Hans,

What you have linked is for the FOR loop, what I had attached is for the WHILE loop.

Only the type of the loop is different, but the concept or logic is the same for both.

Ok, I will try this.

I've thought that this is only a button to stop the loop.

Yes you are correct, what is the differene between 'exit' and 'stop'
