9.1 Database in general

• Upon first entering, the database loaded will be the one that was saved in your REBEL.CFG-file. You can change this (also during a game) by loading a different one via menu "DB-FILES"-load-database or by simply clicking on the displayed name of the database.
• the database uses files with the extensions .DAT, .IX1 , IX2, IX3 and .IX4. If one of the first three files is missing you'll receive an error message. The same applies for making a new database when one of these files already exists.

To view the next games in the database, you have two possibilities:

• You click on top of the screen on the arrow down button (or the PG-DN key) and the next 20 or 40 games will appear (with arrow down button (or the PG-UP key) you can scroll back for 250 pages);
• You click on top of the screen on the letter of the alphabet (or the corresponding key) and again 20 games become visible, starting with the selected letter.
• in the comment section, extra information is available for the game that the scroll bar is located on.
• selected games will be represented as inverse text font
• when a search function (see Searching) is active, the game will be preceded by a "*"
• above the comment section, 6 buttons appear:
  • "Load" (shortcut ALT+L): this will load selected games. You can only activate this when games have been selected.
  • "Delete" (shortcut DEL): this will remove all selected games from the database. Before this will actually take place, you will be prompted for confirmation. Deleted games will be stored in the "TRASH.DAT" database for reasons of security. You can only activate this when games have been selected.
  • "Game overview" (shortcut ALT+G): the game where the selection cursor (>> <<) is on, will be displayed in 15 small boards. For more info on this topic we refer you to chapter 14.3.
  • "Cancel sel." (shortcut ALT+C): this cancels the selection with the result that no game is selected anymore. The buttons "load", "delete" and "cancel sel." will grow pale.
  • "Select all" (shortcut ALT+A): all games will be selected taking into account a former search action. For instance: if you have asked for games that ended with a draw, then all games ending in a draw will now be selected. This can be very convenient to export this selection to another database. Maximum number of games will be 10,000.
  • "­EVALUATE­" (shortcut ALT+M): this will cause REBEL to evaluate the endposition of the game where the selection cursor (>> <<) is on. You can only activate this when two small boards are also visible.
• you select a game by clicking on it, clicking again will deselect the game (shortcut INS)
• you select more than one game by clicking the first one and KEEPING THE MOUSE BUTTON PRESSED until you have pointed to the last game you want to be part of the selection
• if you only want to load one game, immediately click with LEFT button
• if you only want to select a game, click with RIGHT button (shortcut INS)

9.2 DB-FILES

Keyboard users use F1.

• 9.2.1 Load database (DB-menu DB-FILES )
• 9.2.2 New database (DB-menu DB-FILES )
• 9.2.3 Remove double games (DB-menu DB-FILES )
• 9.2.4 Reorganize db (DB-menu DB-FILES )
• 9.2.5 Reorganize IX4 (DB-menu DB-FILES )
• 9.2.6 TRASH.DAT active (DB-menu DB-FILES )
• 9.2.7 Remove TRASH.DAT (DB-menu DB-FILES )
• 9.2.8 Total games: count (DB-menu DB-FILES )
• 9.2.9 Leave database ESC (DB-menu DB-FILES )

9.2.1 Load database (DB-menu DB-FILES )

You now can load another database. The fastest way to do this is using the shortcut ALT+D (or defined button) or by simply clicking on the displayed name of the database.

If you have loaded another database, you will be asked upon leaving the Program if all changes should be saved. If you confirm with yes, REBEL will load this database at the beginning of your next session.

9.2.2 New database (DB-menu DB-FILES )

With this option you can create your own desired database. An example would be collecting (your own) games played at your chess club.

9.2.3 Remove double games (DB-menu DB-FILES )

The database will be searched for double games. Double games are deleted without further notice and will be written to the database TRASH.DAT for reasons of security.

9.2.4 Reorganize db (DB-menu DB-FILES )

Activating reorganization will force the program to sort the entire database by name. Additionally, all deleted games will be permanently removed from the database, thus increasing your free disk space.

Reorganization is only useful if you have added or deleted games.

Before starting the reorganization, REBEL will first inform you whether it makes sense to reorganize by displaying how many bytes of free disk space will be gained.

There are other advantages in reorganizing: some search functions will be performed quicker, and searching on moves, positions or text will show the games alphabetically.

Depending on the size of the database, the reorganization will take some time. When reorganizing, a temporary (and invisible) file will be created. If your harddisk contains insufficient space, reorganizing is impossible.

9.2.5 Reorganize IX4 (DB-menu DB-FILES )

The IX4-index file of the database is the free index file. An index will shorten the searching through big databases immensely. If you use this feature in a clever way, you can find the games you're seeking in a a twinkling of an eye. "Reorganize IX4" gives you the possibility to reorganize the database while automatically adding a free index item. In this option REBEL gives you the opportunity to choose between various common search items or a text you choose yourself. After you've made this choice you will be prompted by the question whether existing free index data should be overwritten or not.

9.2.6 TRASH.DAT active (DB-menu DB-FILES )

Every time a game is deleted a copy will be made in the trash.dat file. When this option deactivated, this will NOT be done and much time will be saved, especially when you delete many games at one time.

9.2.7 Remove TRASH.DAT (DB-menu DB-FILES )

All games that have been deleted before and have been saved for security into TRASH.DAT will now be DEFINITELY deleted. These games will now be gone forever!

9.2.8 Total games: count (DB-menu DB-FILES )

REBEL will count the total number of games in the database. This number will also be visible afterwards in the menu.

9.2.9 Leave database ESC (DB-menu DB-FILES )

This will take you back to the game with board etc.

9.3 SEARCHING

Keyboard users use F2.

This menu offers you possibilities to search your current database for almost every item that a game can be searched for.

• 9.3.1 Searchmask (DB-menu SEARCHING )
• 9.3.2 Search names (DB-menu SEARCHING )
• 9.3.3 Search ECO (DB-menu SEARCHING )
• 9.3.4 Search IX4 (DB-menu SEARCHING )
• 9.3.5 Won by white (DB-menu SEARCHING )
• 9.3.6 Draw (DB-menu SEARCHING )
• 9.3.7 Won by black (DB-menu SEARCHING )
• 9.3.8 No score (DB-menu SEARCHING )
• 9.3.9 List by white name (DB-menu SEARCHING )
• 9.3.10 List by black name (DB-menu SEARCHING )
• 9.3.11 List by eco (DB-menu SEARCHING )
• 9.3.12 List by free index (DB-menu SEARCHING )

9.3.1 Searchmask (DB-menu SEARCHING )

Upon entering this choice your screen will change into a form where you can mark several selection possibilities. Press on the "SEARCH" button after you have defined you search items and the database will be searched for games that meet your specifications.

First of all you'll have three vertical rows of blocks that can be switched on/off. You can only have one of those three activated per line. Meaning of the symbols above the rows:

" || " means (when activated): if this item is found in a game, the game

       will be selected unless other conditions forbid;

" && " means (when activated): this item MUST be present in the game

       otherwise it will not be selected at all;

" != " means (when activated): this item is NOT allowed to be present.

Examples:

1. when "no score" is set on "&&" only the games without a result will be displayed.
2. when "no score" is set on "!=" all games that have a result will be shown whether it will be won, lost or drawn.

Secondly you'll have many items to be specified a bit more such as -white name-, -black name-, -free classification-, -notes-, -tournament- and -place-. You can give a text here that will be searched for in the database.
Other items like -date-, -Elo white-, -Elo black- and -Eco- can be specified in a range. For instance: Elo white =1600 ´2000 will make REBEL search for every game in which the white player has an ELO rating higher than 1599 but lower than 2001. When you set the "!=" block it will result in the selection of games of white players that has an ELO rating lower than 1600 or higher than 2000.

Thirdly you'll see four small boards corresponding with -moves (board 1)-, -position (board 2)-, -pattern (board 3)- and -material (board 4)- search items. What kind of position, pattern etc. the database will be searched for can be defined in the Start menu (see section Set up position for and Current game to). You can change the position to be searched for with the option of the Start menu, or also by clicking on the corresponding board. This also applies to pattern and material but not to moves. Keyboard users can use <CTRL>+<F2>, <CTRL>+<F3> and <CTRL>+<F4>,

Search on moves: the program will search for games containing the exact moves of the currently played game on the chessboard. This can be very useful for opening preparation.

Another 2 examples:

Example (1)

• -white player- defined as "Kasparov", set on "||";
• -black player- defined as "Karpov", set on "||";
• -date- defined =(left blank)-(left blank)-1998 ´(left blank)-(left blank) -1998, set on "&&";

will result in all games of the current database of the year 1998 in which Kasparov had white or Karpov had black

Example (2)

• -white player- defined as "Kasparov", set on "&&";
• -tournament- defined as "Linares", set on "&&";
• -date- defined =(left blank)-05-(left blank) ´(left blank)-06-(left blank), set on "!=";
• -black Elo- defined =2500 ´left blank, set on "!="
• -won by white- set on "!="

will result in all games of the current database which Kasparov played against players with an ELO-rating lower than 2500 in a Linares tournament in all months of the year except May and June and where he didn't win. This example is rather odd, especially for the month item, but it clearly shows that the possibilities are almost infinite.

9.3.2 Search names (DB-menu SEARCHING )

You can input either one or two names here, both of which will be searched for in the database. If you have typed just one name with white, the program will search for all the games by that player, starting with the games he or she played with white. If you type only one name with black, REBEL will start searching first for the games he or she played with black. If you have typed two names, the program will search for all the games played between those two players. This function works via the famous BTREE+ principle and will select games from a database of 1,000,000 games within seconds.

9.3.3 Search ECO (DB-menu SEARCHING )

You will be prompted to define the ECO range for which the database is to be searched. Because this option will make use of the index, searching via this option will probably be faster than via search mask.

9.3.4 Search IX4 (DB-menu SEARCHING )

You will be prompted to define the text of the free index for which the Database is to be searched. Because this option will make use of the index, searching via this option will probably be faster than via search mask.

9.3.5 Won by white (DB-menu SEARCHING )

All games of the database that are won by white will be displayed.

9.3.6 Draw (DB-menu SEARCHING )

All games of the database that ended in a draw will be displayed.

9.3.7 Won by black (DB-menu SEARCHING )

All games of the database that are won by black will be displayed.

9.3.8 No score (DB-menu SEARCHING )

All games of the database that do not contain a score will be displayed.

9.3.9 List by white name (DB-menu SEARCHING )

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by white name.

9.3.10 List by black name (DB-menu SEARCHING )

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by black name.

9.3.11 List by eco (DB-menu SEARCHING )

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by eco code.

9.3.12 List by free index (DB-menu SEARCHING )

This will clear all former search entries and now the contents of the database will now be displayed alphabetically ordered by free index text.

9.4 DISPLAY database screen

Keyboard users use F3.

• you have the possibility to design the display used for the games
• a restriction is made for the names: they have to contain at least 5 characters
• the screen can only contain 72 characters. When you want the names to be completely displayed on the screen, you lose for example the option of two small boards. REBEL can see for itself which possibilities remain and this will be displayed in the menu: unavailable options will have grown pale.
