Actually I was too cautios, the yy[i] trick does work in the foreach loop.
Here's a tested example:
<hansl>
open denmark
list xx = IBO IDE
list yy = LRM LRY
loop foreach i xx
plot_$i <- gnuplot $i yy[i]
endloop
</hansl>
Something a little more general:
<hansl>
open AWM
list xx = YEN GCN STN
list yy = YER GCR LTN
k = 1
matrix my = yy
loop foreach i xx
string s = varname(my[k])
string plotname = sprintf("p%d_$i_vs_%s", k, s)
@plotname <- gnuplot $i yy[k]
k++
endloop
</hansl>
