increase to a value then decrease

[blacksnow]

if I initial x = 0.

I want to increase x++ to x=10, then I want to decrease x-- back to 0.

What is this for?

Do you know anything about loops or arrays?

Have you written any code yet?

[blacksnow]

I want to emulate the LED chase effect on LabVIEW.

I tried to use "case" but I have problem with "default".

Then, I tried to create 2 while loops, 1 for increment and 1 for decrement but i couldn't make the variables connect between two loops. Furthermore, it doesn't what i want.

Oh, althought I has been studying labVIEW not for a long time, I think i know how to use loops, arrays, clusters.

[LandBelenky]

This has two ways of doing it.  At top, the easy way.  At bottom, the really easy way.

Here's one a bit more complex but it gives you more control over the limit of loops.

Surely we can make it prettier than that.

Thank you for super fast reply code.

I am new, so I am afraid that I will make you guys mad with my questions :D. Please bear with me.

But as I am trying to emulate the led chase effect, that mean the code has to be iterated forever, (except when pressing stop).

So, my question is: Is there a way to loop your codes forever, that means: the variables go back and forth between 0 and 9?

And, of course, I am trying to solve this problem, too.

[LandBelenky]

Take any of these solutions and put it inside a loop.

If you want it to go forever, I'd use a while loop and set the condition to "continue if true" and use a constant false.

Can you give it a try and post what you come up with?

Thanks,

LandBelenky's code is what i need.

I learnt a lot from you guys codes.
