JR-BASIC is a dialect of the BASIC programming language running on the Matsushita JR series of microcomputers.[1]

Although it's its own dialect, it was designed to be mostly compatible with Microsoft BASIC. Since it was developed for low-cost entry-level machines, it featured as few functions as possible, in order to save computer resources. Nevertheless, the interpreter was intended to be compact and efficient, with a feature-rich screen editor supporting direct execution of BASIC instructions.

Commands were input by keywords[2] - by pressing a combination of control and alphabet keys, a full command word would be entered. This was faster and more comfortable than typing words letter by letter, as the computer keyboard was poor (chiclet keyboard).
