simple addition problem

[Giridhar_Rajan]

I am facing a problem with simple addition.

I have a number, say 100. Now, I want to add 0.001 to it by pressing a push button.

For example, if I press the push button once and leave, the output number should now be 100.001. On the next press and leave, it should become 100.002 and so on.... Please help me out with this. Thanks

That's easily done with a shift register and a while loop. I've attached a program (LV 7.1) that uses the event structure but could just as easily be done with just a case statement. Shift registers are basic elements of LabVIEW programming. Look at the shipping examples.

Here's one simple way to do this using the event structure.  I have used a timeout event, but you could replace this with a stop button event.  There may be other approaches depending upon what else you are doing in the program.

It's good to see that my approach is the same as that of the great Dennis Knutson!

Thanks a lot Mr.John and Mr.Dennis. That was exactly what I needed.

We'll keep in touch.
