The IBM Implementation
The IBM PC implementation has several features which are absent from the
UNIX version.
Keyboard Extensions
The cursor keys work in the editor as cursor keys.
When not in the editor, the operation of the cursor keys is controlled
by the _ASCARROW environment string:
_ASCARROW:CURSOR
The PC arrow keys move the board cursor.
_ASCARROW:TREE
The PC arrow keys are used for tree traversing,
right, left: down tree, up tree (like > and < respectively)
up, down: last, next variation branch
pgup, pgdn: last, next comment
_ASCARROW:MODE
The operation of the PC arrow keys change depending upon the current
mgt mode: cursor control in edit mode and tree control in tutor mode
Display Extensions
There are three display modes for the IBM mgt:
graphics mode, nographics mode, and nocolor mode
Graphics mode is the default on VGA or EGA systems. The board is displayed
using special graphics characters. The _ASCCHAR
specification is ignored. Note that despite its name, "graphics" mode
does not use graphics mode. It uses text mode and redefines the font.
In nographics mode, color is used to obtain good contrast between the board
and the stones. The "black stone" character is used for both white and
black stones with different colors. Similarly, the "black territory"
marker is used for both white and black territory. The "white stone"
character and the "white territory" character are ignored.
Nocolor mode is the pure text display. The default uses IBM graphics
characters for the borders.
In both nographics mode and nocolor mode, ascii 3 (a heart symbol) is used
the default for the black stone character.
To force nographics mode, put _ASCNOGRAPH in your MGT environment string.
To force nocolor mode, put _ASCNOCOLOR in the environment string.
In either graphics or nographics modes, the display colors can be set
through these environment strings:
_ASCBCOL: black stone color
_ASCWCOL: white stone color
_ASCDAME: dame color
_ASCBOARD: board color
_ASCBG: background
_ASCFG: foreground
_ASCMARK: mark color
_ASCLET: letter color
_ASCMENUFG: menu foreground
_ASCMENUBG: menu background
The colors are:
0 black 8 dark gray
1 blue 9 light blue
2 green 10 light green
3 cyan 11 light cyan
4 red 12 light red
5 magenta 13 light magenta
6 brown 14 yellow
7 light gray 15 white
To choose the defaults, you would execute the command:
set MGT=_ASCBCOL:0 _ASCWCOL:7 _ASCDAME:1 _ASCBOARD:6 _ASCBG:0 _ASCFG:0
_ASCMARK:9 _ASCLET:1 _ASCMENUFG:2 _ASCMENUBG:0
(You don't need to do this if you like the defaults.)
The _ASCINV environment item will swap the foreground and background, and
set the menu background to the background. This is equivalent to pressing
'&' from within mgt.
If you run mgt in graphics mode with a VGA, color 6 is changed to a brown
shade defined by red, green and blue components:
_RED:39 _BLUE:5 _GREEN:33
This color is meant to be used for the board. Other colors for color 6 can be
selected by specifying different values for red, green and blue in the
environment. The range is 0-63.
One person thought _RED:40 _GREEN:30 _BLUE:14 with the background
inverted looked better than the defaults.
A CGA user suggests the following combination:
_ASCBOARD:5 _ASCMARK:4 _ASCLET:2
Some text, CGA and LCD portable users may want to use the _ASCCHAR
string to set the Stones and board characters to some of the "special"
IBM PC characters. The black and white smilie faces may be better for
some as the stone characters. There are single line and double line
border characters. A "dot in the middle" character seems to work well
for the empty points on the board. These characters may be entered on a
PC with the following key sequence:
<press and hold Alt>nnn<release Alt>
The nnn represents a 1 to 3 digit decimal value for the character
entered on the numeric keypad (the number keys across the top do not
work.) The following "special" values seem to work well:
Black stone: 2
White stone: 1
Empty point: 249
Vert. border: 179 or 186
Horz. border: 196 or 205
Upper left: 218 or 201
Upper right: 191 or 187
Lower left: 192 or 200
Lower right: 217 or 188
The first column is for a single line border and the second column is
for a double line border.
The sequence of characters after "_ASCCHAR:" is: black stone (002),
white stone (001), dame territory ('?'), black territory ('+'), white
territory ('-'), empty points (249), hosi points ('+'), vertical
border (186), horizontal border (205), upper left corner (201),
upper right corner (187), lower left corner (200), lower right corner
(188).
In nograph mode the board border characters are ignored, but the stone,
empty point, hoshi points and territory points may be set. In nocolor
mode all may be set.
Mouse Support
The mouse cursor is an arrow in EGA or VGA modes. If you don't want the
arrow, put _ASCMOUSENORM in the environment variable.
The mouse can be used to click on menus, or to click on various parts of
the board.
The top line contains various mode listings.
help quit stone walk move
Clicking on help or quit gets help or quits.
The third word indicates the mode for placing items on the board. In stone
mode, the left mouse button plays a stone on the board, and the right mouse
button sets a stone on the board. (Equivalent to space, and either z or x
respectively.) The color of the stone set is determined by the player
indicator in the lower right corner of the screen. Clicking on the word
"stone" on the top line will change it to "mark". In this mode, the left
mouse button sets or unsets letters on the board and the right mouse button
sets and unsets marks.
The fourth item on the top line is either "walk" or "branch" to indicate the
type of game tree traversal. In walk mode, clicking with the left button
anywhere on the variation window moves down the tree (like the > key). In
branch mode, clicking on a specific variation visits that variation (like
pressing capital letters). In branch mode clicking on blank parts of the
variation window does nothing. In either of these modes, right clicking moves
back up the tree.
The last mode indicator on the top line identifies the menu choice.
There are four different menus you can choose:
move: start end var comment
This is the default menu. Clicking on start or end moves to the start of the
game record or the end of the current variation (like the b and e keys).
Left clicking on var or comment goes to the next variation branch or the next
comment. Right clicking on either one goes to the previous variation branch
or comment.
play: score pass player
These menu items score the game, pass a move (like p key) or set the player
(like the o key), actually changing the Smart-Go record to specify the current
player.
edit: info cut paste delnode addvar
These items invoke the info, cut, paste, delete node, and add variation
commands.
file: save load next prev
These save the game record, load a file, move to the next, or the previous
file. Some loading commands are available directly from the screen.
If you loaded mgt with 2 or more files, then left clicking on the filename at
the upper right will move to the next file, and right clicking will move to
the previous file. If you specified only one file, then clicking on the
filename will load a new file (by name).
To scroll the comment window or variation windows with the mouse, click on the
'+' or '-' character.
To edit a comment, click on the comment window. To move to a node by number,
click on the word "node" above the variation window, and to set the node name,
click on the node name above the variation window.
To select the stone color (like the 't' key) click on the stone that is
displayed on the lower right corner of the screen.
At any (y/n) query, press the left button once to get a 'y' and a second time
to get a return. Pressing the right button twice gets a 'n' and return.
Pressing one button and then the other gets either 'y' or 'n', and then a
backspace to remove the character that is there.
When scoring a game, press right button to score, left button to kill, or
click on the words at the bottom of the screen to undo, quit, or score.
Click on the word "tutor" to leave tutor mode, and click on "read" or "edit"
to enter tutor mode.
Click on the word "short" or "long" to toggle the save format for Smart-Go
files between short and long.
The mode line above the board and the menu line below the board are
omitted if a mouse is not detect on the PC. All of the functions
performed with the mouse have equivalent key commands.
Conversion to Short Format
A batch file called "mgtshort.bat" is included with mgt. You invoke
it as
mgtshort filespec
where the filespec is either a single file or single wildcard specification.
The batch file then invokes mgt on each file, and instructs mgt to save the
file in short format.
This removes any data from the file which mgt did not recognize. Be careful
with this program, since it will destroy any files which are not Smart-Go.
To install it, you need to edit the file mgtshort.bat to refer to the
permanent location of the mgtshort.cmd file.
