For more 80's microcomputer BASIC nostalgia, there's also INPUT magazine (https://en.wikipedia.org/wiki/Input_(magazine)). I spent hours and hours as a kid poring through those magazines. Archive.org has the entire series as PDFS - https://archive.org/details/inputmagazine. They were really good at explaining core programming concepts and the illustrations were also amazing.
BBC BASIC had a built-in inline assembler, which I think also made things easier for people typing in at home. Even if the program dropped to assembly language for speed, the instructions were still human-readable rather than DATA statements full of raw hex.
On the Beeb most listings were BASIC with all the logic there and DATA statements just for in-game assets such as sprites or room descriptions in a text adventure.
