See tilde (~) operator. E.g.: =SUM(A1:A3~C4:C6)

Cannot be used in Data->Validity.

EDIT: Since you need a BASIC function, you may use this:

Function UnionArrays (Arr1, Arr2)
' Expects two 1-dimensional arrays
    Dim result
    result = Arr1
    ReDim Preserve result(UBound(Arr1)+UBound(Arr2)-LBound(Arr2)+1)
    Dim i As Integer
    i = UBound(Arr1)+1
    Dim n As Integer
    For n=LBound(Arr2) To UBound(Arr2)
        result(i) = Arr2(n)
        i = i+1
    Next n
    UnionArrays = result
End Function

a = array("a","b","c")
b = array("d","e","f")

c = split(join(a, ",") & "," & join(b, ","), ",")

works only with strings inside array, and maybe partielly with integers or floats… python works with any objects inside lists

It's easy as pie!

Now that I'm thinking about it, OP does make 3 arrays (or lists, as Python, pictured above, calls them) which is using same syntax some languages use, and I don't remember seeing arrays made that way in Calc. I could be wrong, though. Python does make many things much easier than any other language AFAIK.
