I am trying to locate all instances of a value displayed in an array. For example if I had an array like : 1 2 3 4 5 5 6 7 8 2 1 and I use 1D search program to find 2, I should get an array of two locations in the output. I tried using the output as an array and gave me broken wires.please guide me if possible.

You might think 2 = 2, but in reality they are not exactly 2. You can switch to integers instead, or using some trick like machine sigma comparison.

You are almost done. You are wrong with the value of zero. The function gives you value "-1" if the value is not found. So you will get a single element array with value -1 if no match. If there are matches, you get their indexes, and a closing "-1" indicating there are no more matches: Or you can just use the OpenG Array addon function. Using this function, you only get the indexes of the found elements. If the search results in zero match, you get an empty array simply:

I guess you found my old code. (please have some respect and don't chop it up like that :o. You also need to stop the loop if the search returns <0. If it returns =0, you have a valid match) "-1" is needed if you search for one and it is not found. Here you search for all instances, so if none are found, you'll end up with an empty array, which seems to be a clear result. The output is now an array, not a scalar. If you want an array with a single -1 element, just detect if the result is empty and switch the output after the while loop before the indicator.

That's impressive. Such a menial task but you recognized the code as from your old post from 2005?
