Finally completed day 10 of #adventofcode in BBC basic on the BBC micro (emulated with BeebEm)

It's been interesting to go back to old school.

I've been able to do a level of TDD, but I gave up on pretending to be able to do OO in a language which really has no features to support it. Progress improved after that.

Dealing with the odd file structure was an early challenge, basically had to write a key to disk util.

At least can mostly avoid GOTO except for error handling
