Functions in IDL are not like functions in, e.g., MatLab. You can only return one value. To do this, you must use a procedure and put the output variables in the calling statement.

pro foo, a, b, a_plus_b, twoa
a_plus_b = a + b
twoa = 2*a
end

;-----------------
a = [1,2]
b = [2,3]

foo, a, b, c, d

print, b, c
