cat() is certainly a reasonable way to print results (print might also
work) -- really whatever works for you, though I might prefer your
function only return the values and that those are printed
automatically at the top level.

Also, I'm not sure if this is what you're getting at so feel free to
ignore it if I'm off base, but
