It was a quite advanced BASIC and featured a runtime threaded codecompiler that compiled the program when one entered the RUN command. The dialect was very close to MSX BASIC. The major differences were the lack of the PLAY, SOUND, VPOKE and PUT SPRITE operators, the inability to open several files at the same time, and the inability to use more than one operator on one line. Only the UKNC version had a full-screen editor. Machine-dependent features, like graphics operators parameters and PEEK/POKE addresses were also different.
