An INTEGER control takes numeric values in a specific range, while an
ENUMERATED control takes values that are not numerically related (but
that are _internally_ represented as integers in a specific range).
In your case, you'd probably want to use an enumerated control with the
range 0..3, which maps to the four names "0", "1", "100" and "101".
