[Gnuplot-info] string variables and iteration

[atoms.h <tho...@gm...>]

Hi all,

i have a strange problem regarding string variables and iterations. What I'd
like to do is to handle operations for several input files in a loop:

$ list = "file1.dat file2.dat file3.dat ..."
$ item(n) = word(list,n)
$ do for [i = 1 : words(list)]{
$   file = item(i)
$   total = `echo $(awk '/Total/ {print $4}' @file)`
$ }

This always complains that 'file' is not a string (for the awk command).
Outside the loop, however, it works:

$ list = "file1.dat file2.dat file3.dat ..."
$ item(n) = word(list,n)
$ do for [i = 1 : words(list)]{
$   file = item(i)
$ }
$ total = `echo $(awk '/Total/ {print $4}' @file)`

So there seems something strange is happening in the loop which I don't
quite understand. Like if the awk command would be executed first or
something...
If anyone has some inside or better idea I would very much appreciate it!

Kind regards,
Thomas
