I don't mean lisp-1 (implementation standard) or ansi maclisp (implementation standard) but real standard of the artificial language, anons say, an algebraic language for the manipulation of symbolic expressions, defines the lisp language but this can't be true with the direct implementation details on an ibm 704 and 709 it has and the machine language it defines. It also says "incomplete" or is there no good standard for this and it's sourced like a quasistandard.
