Minesweeper for the TI-85. Essentially matches the
    Windows 3.1 game.


 
    To start this program, run MINE. The other program, ZZCLR, is
a subprogram.
 
    When the program starts out, it will ask you for a value for
Xsize, Ysize, and Mines.  These values are the the width and
height of the matrix containing the mines, and the number of
mines to place within that matrix.  After these values have been
entered, it will place the mines and set up the matrix (progress,
in terms of columns completed, is shown in the lower right
corner).
 
    When setup is completed, the matrix will be displayed as
periods on the screen.  This represents an unknown square.
The X is your cursor.  On the right side of the screen is,
from top to bottom, your column, row, number of mines
remaining, and whatever is under the cursor (number, period,
or plus).  The arrows move the cursor around the screen.  If
the grid is larger than the screen, you can move off the
screen to see other portions of the grid.  The F keys
perform actions; F3 is clear around (analogous to pressing
both mouse buttons in the Windows game; it checks if you
have marked the correct number of mines around a square, and
if you have, it clears all unmarked squares around it), F4
is mark as a mine (replaces the mine with a plus, and
disables F3 and F5), and F5 is step (tells you the number of
mines around a particular square).  If you step on a blank
square, all squares around it are cleared; this can take a
while.  If you step on a very large blank area, it is
possible that the entire area will not be cleared.
 
    When all of the spaces that do not contain mines have been
cleared, you win.  If you step on a space that contains a mine,
you lose.
 
    If you suddenly find yourself having something better to do
(teacher asked a question?), hit Exit.  If you do this, next time
you run the program it will ask you if you want to start a new
new game (New), or continue an old game (Cont).
