Message-ID: <1650003@hpkslx.mayfield.HP.COM> Date: 28 May 91 04:38:02 GMT Organization: HP Response Center Lab Lines: 10 I was playing around with siod ("Scheme in one defun"), but it looks like it doesn't have an append function. How would one write append, using just car, cons, and cdr? Since the format of cons is (cons elem list) instead of (cons list elem), I don't see an easy way to do this.... Thanks! -Ted
