Hello, I want to remove the repeating objects in roArray. How can we do that?
ex if i have a array:{
"A"
"B"
"C"
"A"
"B"
"C"
"A"
"B"
}

my output array should be like:
{
A, B, C
}

Thanks,
Pradeep

There's no built-in way to do that, but you can write a simple loop and keep track of what items you've seen with an associative array. Something like this:

function RemoveDups(array as Object) as Object
    out = []
    seen = {}
    for each item in array
        if seen[item] = invalid then
            out.Push(item)
            seen[item] = true
    end for
    return out
end function

I haven't tested this, it might require some tweaking.
