Hello, Names of symbols must follow certain rules. One easy work-around is to quote them and turn them into string contants, for example F["\[UpArrow]"] = 1 (no need for delayed evaluation in this case, by the way, where everything is constant). In StandardForm and TraditionalForm (unless you turn on the option ShowStringCharacters at the notebook level), you won't see these double quotes. Hope this helps, Tom Burton On 10/7/03 11:01 PM, in article bm0jp3$pr2$1 at smc.vnet.net, "Nicholas Konidaris" <npk at astro.ucsc.edu> wrote: > I am interested in using symbols* in my mathematica routines.
