Just to chime in, I recomend giving it a shot and use a collection or
dictionary, even if an array will work. There will come a time when
you will need to use one of these techniques and the more you get
comfortable with them now the better. Another thing that is worth
looking into is using ADO recordsets stored in memory. They are easily
sorted and have number of useful methods, like 'Find', and many other
useful techniques that are good to have ready in your back-pocket. ADO
recordsets require you to reference the appropriate Microsoft ADO
Extensibility library.

Good luck—Lonnie M.
