There's program much like that in the book Starting Forth, called "File system" it has 3 screens, if you take only what you need , you may be done in 1 or two screens, and you can store other data in that system like names and phone numbers. trick is you erase record memory you don't need , which then gets reused on next record add, it checks if it is empty.
