Bryan, as an application example to Brad's second solution, the URSC
MetaStock kit uses a custom dll that matches the current chart's symbol
to any symbol found in any number of text lookup lists, thus enabling it
to match the chart to a particular index or favourites list.
For example, if the chart's symbol matches the selected symbol list by
the dll (say, MyFavs-05.txt), then it returns a true (+1) boolean value,
which could then be assigned a discreet or unique value.
