Any simple way to create for loops?

[Mojca M. <moj...@gm...>]

Hello,

Is there some way to do something like this in gnuplot apart from
using external script?

    for [i in "0.01 0.1 1 2 3 10"]
        filename=sprintf("name-%g.png", i)
        command=sprintf("./script %g", i)
        set output filename
        plot command using 1:3 with lines
    endfor

I've read about reread, but I don't know how to apply it here except
if gnuplot supports some array data structure which I think it doesn't
(but maybe I'm wrong), or if I create a function with a long series of
    f(x) = (x==1) ? 0.01 : (x==2) ? 0.1 : (x==3) ? 1 ...
but in that case I would probably prefer to use external script for that.

Thanks,
   Mojca
