Converting Notebook from DOS to Windows

See attached documents. I have been using a database program called Notebook that was part of WordPerfect Library when we bought the program in 1988. The software is DOS based but the data when saved to a merge file works with WordPerfect 2021 as you can see from the attached. The program just needs to be made Windows compatiable and would be an excellent add on to WordPerfect for law firms or business that cannot afford to pay for document services.
