Color BASIC is the implementation of Microsoft BASIC that is included in the ROM of the Tandy/Radio Shack TRS-80 Color Computers ("CoCos") manufactured between 1980 and 1991. BASIC (Beginners All-purpose Symbolic Instruction Code) is a high level language with simple syntax that makes it easy for novices to write simple programs. Color BASIC is interpreted, that is, decoded as it is run.
