Hello,
I am trying to display a LED on a every bit of every port sequentially.
To keep from having more than 1 led at a time on, I want to rule out all odd numbers.
Display 1 then 2, then 4, etc, on every port. The program is not complete i am aware, but I know that
nothing is going to work as I want the way it is.

Please look at the switch on the switch in macro "A". That is where I am not sure how to get the switch to choose 1 or 2
depending on an odd or even number.
If anyone can help me with this, I would appreciate it.

Program attached.
Thanks in advance.

To test for odd or even, just AND with 1 ...

Thank you for the reply,
But I just don't understand the A & 1 portion. Is there still a fmod in the program?
Or did you manage to remove that.
It seems you are treating 1 as a variable..........
Please send code with response.
Sorry, for the ignorance, I am new to what you are doing. NOT a Trump voter............

The solution Leigh posted I did not really understand.

Could someone could give me some further help?

Please insert what he had in mind into my code attached, so I can single step through it and learn it.
Thank You.

Combining this message with your original question.
Means perform a bitwise AND operation on A with the number 1. The result of this operation is equal to zero (decision branch NO) if A is even and equal to 1 (decision branch YES) if A is odd. See wikipedia for an explanation on bitwise operators.
To use it in your program just input the code shown above in the condition of the decision icon.

Thank You for that, got it working!
