It is designed to improve the standard Hi-Resolution Graphics text mode displays offered in the Color Computer 3. This is accomplished thru the use of a 640x225 Hi Resolution Graphics Display. The program is fully integrated into the existing Basic Rom software. This enables it to be used with standard Basic programs as well as machine language programs. The format of the Display when the program is first executed is 80 characters by 24 lines. This can be changed to character sizes varing from 14 to 212 characters. You can also switch back and forth between the Hi-Res format and the Standard 32x16 format for complete compatibility in almost all situations. The package also includes other control code functions which allow various screen functions comparable to standard video terminals. Some of them include: Reverse Screen, Reverse character, Underline character, Double Size characters, Erase to end of line, Erase to end of screen, Clear Screen, Home Cursor, Bell tone and more. There are controlled thru use of control code characters sent via the CHR$(n) Basic statement, the Control functions of the Keyboard or thru Machine language routines.
