Thank you so much. It is nice to finally see someone answer my
question right off the bat. Usually when I post these types of
question, I get about 5 "Why are you doing it that way?" type posts,
along with 3 completely off topic responses and at least one "Let me
see your UML." If I am lucky, after about 15 posts, I might get one
half answer such as "Why don't you use an array?" Honestly, thank you
for answering the question. I wish there was a point system so I could
give you some points. I will try either of the suggestions and let you
know.
