Mileage Converter

Howdy folks! Recently I started to re-dable (now that’s a funny word, if in fact it is a real word) with BASIC programming. Programming in BASIC, for me, goes all the way back to being twelve to fourteen years old, somewhere in the early 80’s. That’s when the Apple ][+ ruled the personal computer world!

I found an App for iOS, Misoft Basic!, that purported to be an Apple staff favourite for its nostalgic feel, much like the old AppleSoft BASIC of the day. My father thought it would be fun to try some programming again and suggested we work together on a mileage converter. I agreed but went a little overboard and wrote the whole thing one afternoon. So, after cutting my dad out of the fun, he is taking it a step further and is giving it a graphical interface, as opposed to my purely text offering.

I am including the code to what I’ve written so far if you’d like to try it out. Be aware that not all versions of BASIC use exactly the same syntax or commands but if your willing to give this a go, you probably already know that.
