Yes, see the "Foreach loop" section in the loop chapter 12 of the manual: "Note that if you use this idiom inside a function (see chapter 13), looping across a list that has been supplied to the function as an argument, it is necessary to use the syntax listname.$i to reference the list-member variables." (Of course, $i must be replaced with what the loop index is in your case.) > function matrix MatOrderDist (list ls, list lsB[null]) >     if exists(lsB) Hey, we had this before, don't use exists() with list function args. It will always return 1, even for null. Use nelem() directly (with lists only!). >     loop foreach item ls -q >         to_plot[r,1] = min($item) OK, this would need to be ls.$item instead. >                     loop foreach item lsB -q >             to_plot[r+offset*(r-1),1] = min($item) And this: lsB.$item. hth, sven _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
