5. Rebel Database5.1. Rebel Database FormatThe Rebel database format is published by Schröder BV to help programmers writting tools for handling Rebel database.
5.2. Rebel Databases copied from a CDWith Rebel Century you will get a lot of databases on the product CD, not copied to the Rebel directory during installation. If you want to change such databases, you have to copy them (.DAT, .IX1 and .IX2 file - newer databases may also have .IX3 and .IX4 files) from the Rebel CD to your harddisk. By default Rebel Century looks for databases in the directory CENTURY\GAMES, so it is a good idea to copy the databases into this directory. Before you can uses the databases, delete the readonly flag for the copied files. In DOS mode you can delete the readonly flag for a Rebel database (with the name database in this example) by typing in: attrib -r database.* Under Windows 3/95/98/NT you can delete the readonly flag by starting the File Manager (or Explorer under Win95, Win98 and NT 4) and selecting all files of the Rebel database (i.e. database.dat, database.ix1 and database.ix2 in the above example). The open the menu 'File' and choose the option 'Properties' in the appearing bix deactivate the readonly flag. 5.3. Importing ChessBase Files into a Rebel DatabaseThere exists at least two ways of importing ChessBase files into a Rebel database:
Export to PGN in ChessBase
Using Rebel's TB.EXE utility TB.EXE can't convert the new ChessBase 6/7 .CBH format. 5.4. Joining Rebel DatabasesRebel databases can be joined (append a Rebel database to another one) with the freeware utility program import.exe. 5.5. Rebuilding the Rebel Database Index FilesIn case the Rebel database index files (.IX1, .IX2) get corrupted or even lost, you can rebuild the files with the freeware utility rdbindex (ca 21 kB). rdbindex.exe is a DOS program. Call it with option -h to get usage information. 5.6. Marco Aspes' Rebel Database UtilitiesMarco Aspes (vaspes@libero.it) wrote a set of Rebel database access utilities (reb_util.zip ca. 66 kb):
5.7. How to Search for Black Wins in a DatabaseEnter the desired player's name in the "blackname=" field and enter score="+". 5.8. Analyzing a DatabaseThe "Analyse database" function is for position databases only (i.e. each game in the database is a position only). If you want to analyse complete games, use the "Analyse Game(s)" function in the database menu "Utilities" 5.9. Fred van Engen's PGN Export UtilityFred van Engen wrote a DOS based Rebel to PGN database converter. With this utility you can convert the Rebel database files into PGN files.
5.10. Deleting Double Games from DatabaseOpen Rebel's database window by pressing ALT+L, or clicking on the L button and select the function "Remove double games" from the DB-FILES menu. Rebel will now look for double games and delete all the games, marked as double, from the actual database. Rebel uses the following criteria to delete double games from a database:
If all 3 checks are true a game is marked as "double" and is removed from the database.
Important Note
Table over nnnnnn Games Press any key.... Program continues without inserting new games However the process continues although with less information. If you set Rebel to a hashtable of e.g. 28 Mb then the "remove double games" function can handle databases of 2 million games.
