Mind the fact your function Julia has no return value, or do you wish to use "amounts" as returned value? Also mind the fact a general rule affects capital letters to built-in functions. You can use: julia[x_, n_] := NestList[#^2&, x, n] ----------------------------------------------- Jean-Marie THOMAS Conseil et Audit en Ingenierie de Calcul www.cybercable.tm.fr/~jmthomas ------------------------------------------------ -----Message d'origine----- De: Veit Sanner [SMTP:sanner@biosys.net] Date: jeudi 19 fevrier 1998 02:33 A: mathgroup@smc.vnet.net Objet: [mg11079] Complex Number problem Hi. I tried the following function to generate the Julia for a certain point. Julia[x_,n_]:={amounts={x} For[i=1,i<=n,i++,x=x^2;AppendTo[amounts,x];];} But Mathematica always answers with tha same message: Set :: write : Tag Complex in x+y I is Protected. How can I set this tag to unprotected? ciao Veit
