However if I converted the above structure to a switch control structure the script compiled fine. Have I stumbled upon something here? It kind of makes sense to me because the compiler may be having trouble knowing which control structure *else if anotherstatement* belongs to.

It's a known issue when the compiler gets confused about which "else"
goes with which. You can either rewrite the section using the long form,
or put a carriage return after the last line of the embedded "end if". I
tend to use the short if/else form a lot myself and I see this all the time.
