BBC BASIC V
I'm starting to write some BASIC code using a minimal version of the RISC OS operating system (called the Pico distribution) running on a Raspberry Pi. It's interesting to me the long history of this operating system (RISC OS) and programming language (BBC BASIC), and the fact that its been released as open source in the past few years. All this and it can run on modern ARM-processor hardware such as the Raspberry Pi.
The attached files were created on a Raspberry Pi 1 Model B, running RISC OS 5.25 and BBC BASIC version V. They are in BASIC-tokenized format so cannot be opened in plain-text format.
