The second part of

   plot [i=1:4] fname(i) us 1:2, '' us 1:2

cannot work. '' just contains the last file name, in verbatim, that was
in the plot command. It doesn't expect a function, and especially cannot
contain the whole iteration. The error message could be a bit clearer,
but obviously nobody thought of the specific misuse you tried. ;-)

You have to repeat the iteration :

 plot [i=1:4] fname(i) us 1:2 w lc i, for [i=1:4] fname(i) us 1:2 w lc i


Best, Karl
