Close, but no cigar.  The string-based list does not work like that 
because its elements evaluated by the for loop are still strings.

The following would have worked, though:


	plot for [i in "6 8 9"] 'file' u 2:int(i)

The following may be more useful.  See "help arrays" to understand what 
it does:

	n = 3
	array list[n] = [6, 8, 9]
	plot for [i in 1:n] 'file' u 2:list[i]
