It features an interactive visually-driven system with a consistent user interface. Online help is available for every input to explain the function keys and fields on the screen. It can be customized to meet a company's needs with the C/BASE 4GL application generation system, with which you can change file structures, report formats/layouts, and data input screens. Also, new applications created with C/BASE 4GL or C code can be linked to C/BOOKS accounting modules.
