How do I get MS-DOS to use the 50-row mode of my VGA? I can set the video mode so the BIOS uses all 50 rows when I do: set cursor to <row>,<col> display <char> for <row> = 0 to 49, <col> = 0. As soon as the program exits, the prompt scrolls the top 25 rows, and appears in row 25. From then on, only the upper 25 rows are used (but the lower 25 rows displayed by my program remain on the screen, unchanged). What magic do I need to perform to get MS-DOS to use all 50 rows? Why does MS-DOS care, anyway? Tom Roberts att!ihlpl!tjrob
