Hello Wolfgang,
thanks a lot for the very nice code :) :) :)
The second example (H_2^+) does not return expected result - it should have been
H\lohi{2}{+}
instead, but I don't require such cases for the current document, so I
guess that I'll just replace the old macro with this one for now in
order not to get distracted with TeX problems too much :)
Thanks again,
Mojca
