Program: BIOS Window Extension
Command: WINDOW (R,C) TO (R,C)
Display: Color graphics or
Monochrome display
This program defines a window on the screen in which all
subsequent activity will take place. The window is
specified by giving the coordinates of the upper left and
lower right corners in terms of rows and columns. The upper left
corner of the screen is (0,0). The format of the command is
fairly free, the only requirements are that each coordinate
pair start with a left parenthesis and be separated by a
comma. The format shown above is suggested for clarity of
interpretation.
The areas outside of the current window may be written to
directly by any of the usual commands (in your favorite
language) which allow direct coordinate specification.
