At my first job, our order entry system was written in BASIC. The second version of the system was written in QBasic. I wrote lots of test and demo code in the language. We used it in all our manuals, since it was the one language that we knew our customers (mostly engineers and scientists) would be able to program in. I started writing a spreadsheet in BASIC, but never finished. I wrote a couple of simple games in it also. There are more, but I've forgotten about them. Now, if we expand the definition to include VisualBASIC, then the amount of production software written in the language explodes into at least 100,000 programs.
