>Hi Bill - thanks for the info. The Y,N,Maybe was just an example, but will it work with other letters of the alphabet, too? As in G for gas, E for electricity, D for diesel, etc? I am not able to try myself at the moment, but am curious as heck!

The limit, is either 128 or 256 bytes- I forget which one.
Otherwise, you can put whatever you want there.
I mostly use it for whole words e.g. John, Mary, Peter, Jack, Aristotle but yes, G, E, D would be fine.
