Sticking with BASIC for now. There is much left for me to learn in this language.
New fork for this discussion: someday, if I ever have bunches of free time (ha!), maybe I should learn another high-level language. I now realize that could be any number of choices: C, COBOL, Forth, Fortran, Pascal, Java, and others .... which would be easiest for a liberal arts person like me to transition into from BASIC, and which would best serve me as a tour guide at the museum?
BASIC is the universal language for demos in a museum setting when you're just showing something that you can execute in real time. There is nothing wrong with concluding that formal programming is not for you, it's a lot like music, painting, writing, etc. Most everyone has their strengths and weaknesses. A person can be a great programmer but incapable of writing a good user interface, directions, help screens, etc. Maybe you can team up with a programmer...write the interface and screens for museum projects how you'd like them and then get someone to code them up. In most businesses the programmers are not also tasked with anything other than the actual programming itself, a team contributes to the finished product. Bill
