Ah, that was my mistake. Sorry for the noise. I don't know why I just
did not make use of the $-accessor, but tried to do some selection. The
following works exactly as (I) expected it :-)
<hansl>
strings S = defarray("A", "B", "C")
loop foreach i S -q
eval $i
endloop
matrix M = seq(1,3)
loop foreach i M -q
eval $i
endloop
matrix M = mnormal(3,4)
loop foreach i M -q
eval $i
endloop
</hansl>
@Jack: I just wanted to save time by coding less, as <loop foreach i S>
is a bit shorter than <loop i=1..nelem(S)> :-)
