Recursion in RL Functions

Today I was thinking if it were possible to create recursive functions in the RL Language, so I made a small test by calculating factorials. I started by defining the function as:

  function factorial(long  x) returns long {
    if( x == 1) {
           return 1;
    } else {
           return x*(factorial( x-1 ));
       }
   }

Next, I just ran it by using:

  println("The factorial of 12 is: " + factorial(12) + ".");

and this gave me the expected result of:

  The factorial of 12 is: 479001600.

so, this seems to work fine.

Next thing will be to try recursion for facts, and of course for rules... More about that later.
