Program to proof play/enter chess games for export to a word processor.
Command line options:
-r or -i <file name here>   Reads this file first before accepting
                            keyboard data.
-w <file name>              Name of work file (default chess.wrk)
-o <file name>              Name of output file (dft. chess.txt)
                            New games are appended to this file.

Game entry rules:
Checks must be announced with either + or #.
Program is pre-PGN. Example: 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5
                             5. Nge2  Even though Nce2 is illegal, a
                             search is done for all similar pieces which
                             can move to that square before check status
                             is investigated.

After each move or command, the "Return" or "Enter" key must be pressed.

Notation must be perfect.  If only one piece can move to a square, no
descriptors are allowed;  if two similar pieces can move to a square,
you must specify which.

Promotion indicated by a symbol for a promoted piece at the end of the
move such as d8Q+ or gxh1Q.

Castling is indicated by two zeros (00) for kingside and three zeros(000)
for queenside.

A game is finished by "1:0", "0:1", or "Draw"

The program ends when the word "end" is typed for either the players'
names or as a move.  You can abandon the game you are on by entering the
word "can" and you will prompted for the players for the next game.

Shortcuts:
wnn or bnn  where nn is a two digit number.  Go to a specific point in
the game.  Both digits are mandatory since b6 for example would be
interpreted as a pawn move.

b        Backup a half-move (ply).
<return> Play the move already on file for that ply.
h or H   Hide the board.  Any key redisplays it.
f or F   Fast forward from this point to the next notation error.

Comments: A ? or ! at the end of a move, as is text within () becomes
part of the move when written out.

This program does not perform any word wrap.  That is reserved for the
program you use to read and/or print "chess.txt".

Chess2 writes on video memory.

Example of use:  Someone entering a game from a NCR scoresheet has to
assume which Black rook moved to c8 on move 11 and realizes on move 38
his guess was wrong.  Enter "b11" then enter Black's actual 11th move.
Press "f" to continue the game.  The game continues until Black's 20th
when another notation error involving a black rook turns up.  After
you correct the move, press "f".  Finish entering the game.

The user must determine if this program will be useful and
assumes all risk.
