  In the POV-Ray documentation? If you are using POV-Ray for windows,
write the word "select" (just in the scene file) and press F1.

  See also http://povray.org/documentation/view/3.6.1/228/#s02_02_01_03_04

#declare Factorial =
  function(A) { select(A, 1, 1, A*Factorial(A-1)) };

#declare Value = Factorial(8);
#debug concat("Factorial of 8 is ", str(Value, 0, 0), "\n")
