Thanks for all of the replies.
I think I can add most all of the suggestions without too much difficulty. Some may take longer than others(lunar cycles). The program should be less than 5 meg. If it gets too big I make break it into two programs, one fishing log and one pond management program but I don't see any problem with size.
The program will be free standing, meaning you will not have to buy any other program to run it.
This may take a few weeks because I have another job and I program for fun but I will get it done.
Thanks, Mike
