Question about computer analysis

In the openings section when
one is playing a game against the computer--the
"try yourself the _______ opening...". What is
the meaning of the shown sequence of moves that
the computer keeps recalculating with each new
move? Also, what does the "score" right above
that indicate?
One more thing, is it possible to reverse a move
in that section, i.e. go
back one or more moves without starting over?
Thanks

Dear viewer,
The
meaning of the shown sequence of moves that the computer does is
just to let the viewer watch the "thinking" process that is
undergoing.
The Score
parameter shows (to the computer's point of view) who is ahead
in the game. A Pawn value is 100 points, Bishop and Knight are
300 points each, Rook is 500 points and the Queen is 900. So, at
the beginning of a game if you play white and make the first
move, the score shown by the machine analysis after making his
first move could be 0 since both players are equal at this point
of the game.
If you like to review this process,
start a game and give a piece away. If you choose to lose a
Pawn, the score will show an increase of 100 points. A minus (-)
sign on the left side of the number means the computer is down
in the score.
Of course the score yielded is
related to piece material gain but also to positional and
strategic advantage. You could have many more pieces than the
computer and if the score shows the machine is ahead of you is
because it will get a more favorable game later or checkmate you
in a short time. A score of 10,000 means either Checkmate, Draw,
or Stalemate.
The Depth parameter shows the
maximum search depth in plies. You can increase this parameter
for a better play from the computer but increases thinking/reply
time.
The Time parameter is
the maximum thinking time in milliseconds. Again, you can
increase this parameter for a stronger computer's reply. This
parameter is set at 5000 milliseconds (5 seconds) by default.
On the reversing a move question,
Lokasoft Chess program does not allow a player to go back one or
more moves without starting another game.
