Fibonacci sequence by recursive algorithm fail

[Tim Wessman]

The CAS is case sensitive. There is no function or keyword called "Return"

Code:


#CAS
    fibo(n):=
    begin
        // versión 0.0.1 April 20
            if n≤1 then 
                    return n;
            else
                    return (fibo(n-1)+fibo(n-2));
            end
    end;
#end
