BBx is the original name for the Business Basic interpreter developed by BASIS International in 1985. Subsequent generations of BBx have been BBxPROGRESSION/2, BBxPROGRESSION/3, PROGRESSION/4, PRO/5 and Visual PRO/5. BASIS estimates that over 1.7 million end users worldwide run applications built with their products.
Current BBx dialects include PRO/5 (a character mode interpreter for Linux and Unix environments), Visual PRO/5 (a graphical interpreter for the Microsoft Windows environment), PRO/5 Data Server (a data server for PRO/5 data files), the BASIS ODBC Driver (a Microsoft Windows ODBC driver for PRO/5 data files) and BBj (a superset of the BBx language and environment implemented in Java).
