Hi, do you know maybe is there a possibility to change a name of a variable in a loop? I'm not exactly sure how to explain it, so maybe instead of my words I paste a basic example that express my query: a1 = 1; a2 = 2; a3 = 3; func[g_] := g; Summ = 0; For[i = 1, i <= 3, i += 1, Summa += func[ai]] So something like this... I have tried to deal with this like with strings and have put func[a<>"i"] but it didn't work (quite logic). The general problem is much more complicated, this is only a part of it, so please do not suggest me how can I sum up three numbers, this I believe I know :) I would very appreciate any hints, Best regards, Kazik
