Abstract
User-defined special forms are created by applying the special form SPECIAL, which is completely analogous to the special form LAMBDA, except that an unnamed-special-form-typed-pointer to the dotted-pair of the input arguments is returned, so that the result will, upon later use, be interpreted as a special form rather than a function. An unnamed-special-form-typed-pointer has the typecode 15.
