SUMMARY

A character-based MS-DOS application does not fill the entire screen when it is running in a window. To make the application fill the entire screen, run the application in the full-screen mode.

MORE INFORMATION

An MS-DOS application running in a window fills the width of the screen when maximized; however, the application fills only a percentage of the height: 
Screen Resolution      Approximate Percentage of Screen
-----------------      --------------------------------

EGA (640 x 200)        85%
VGA (640 x 480)        85%
VGA (800 x 600)        50%
VGA (1024 x 768)       40%
This behavior occurs because a standard MS-DOS screen only displays 25 lines of characters at a time. When an MS-DOS application is running in a window, the regular MS-DOS screen font is replaced with a smaller Windows font. Unlike a Windows application, which displays more lines of text when the window it's in gets larger, the MS-DOS application only displays 25 lines at a time.
