Most of the other graphics modes have 25 text lines when using these routines. MORE INFORMATION ================ The following graphics functions are the routines concerned with text placement and output: _displaycursor _gettextcolor _gettextposition _outtext _settextposition _settextcolor _settextwindow _wrapon The line numbers stated above are based on the default 8 x 8 font size of the IBM ROM BIOS.
