X$! Notes for system managers
X$!`20
X$! The scoring section can be deleted completely, but adds much to
X$! the fun while involving little overhead. Approximately 45 scores are kept
V`20
X$! for each of the three levels. The username is kept as part of the score,
V so`20
X$! that each user gets his/her invividual scores highlighted, but the name i
Vs`20
X$! never displayed.
X$! The scoring system needs a directory that has world read access, but not
X$! world execute. It will create three files (one for each level) with
X$! world read and write access. (NB. It is left to the system manager to set
V`20
X$! the protection of the directory itself to w:r to prevent wildcard`20
X$! searching). The protection is only 'security through obscurity.' In `20
X$! principle, users could write their own routines for updating these files,
X$! so the file names and directories must not be known. Note that the only
X$! reference to the directory is deleted later in this procedure.`20
X$! The scoring files are VAX indexed files, indexed by score. As entries are
X$! created and deleted, they may benefit from a convert/rebuild occasionally
V.
X$! Finally, if you don't want to add yet another logical name to the system,
X$! then edit the word "mine_help" on line 91 in minesweeper.bas to
X$! wherever you keep public games and their help files.

XMinesweeper
X
X
XThis is a reverse-engineered version of the Minesweeper for Windows program.
XIt runs on VT100 compatible terminals under VMS.
X
XYou are given a grid with a random array of mines.
XThe aim is to identify the location of the mines and to clear all other`20
Xcells. When a cell is cleared, you are told the number of adjacent squares`2
V0
Xthat contain mines. Adjacency is vertical, horizontal and diagonal.
XIf you attempt to clear a cell that is occupied by a mine then it will`20
Xexplode and the game ends. The exploded mine and any falsely flagged mines`2
V0
Xare shown flashing.

XF or f or M or m or X or x to flag the presence of a mine. Will also`20

XUnknown locations are shown as dots.
X
XCleared locations are numbers representing the number of adjacent squares`20
Xthat contain mines. Adjacency is vertical, horizontal and diagonal.`20
