I remember back in the DOS days being able to type a tiny program into DEBUG.COM that would set the screen to 80 x 50 mode! It was one of the first things I would do on a machine if I didn't have my floppy disk of favorite tools with me. It was just a couple instructions, like MOV AX this and INT 10h that. Now I have to go find it!

I thought the MODE command could do this.

  MODE CON LINES=50 Indelibly burnt into my long term memory. You needed an EGA or higher graphics card though.

    There was also LINES=43 for EGA (640×350, rather than VGA's 640×480). MODE CO80 was for 80-column colour. ``MODE MONO'' switched to MDA/monochrome VGA mode (if you hadn't used &b700-b7ff for a UMB.) MODE CO40 for the 40-column mode intended for the original IBM PC when used with an analogue TV set as its display.

      Didn't 'MODE MONO' need a Hercules graphics card though?
