Catherine, it's a little hard to know what your real code is doing from this
toy sample. Usually, if you want to work with "variable variables" as you're
suggesting here, the better approach is to use one dictionary instead of many
variables. Then you can deal with them as a single collection much more
conveniently.
Can you show us the real code in question? It will be much easier to make a
good recommendation if we can see what you are doing with these variables.
