Rebel 9 FAQ
5. Rebel Database
The Rebel database format is published by Schröder BV to help programmers writting tools for handling Rebel database.
With Rebel 9 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) from the Rebel CD to your harddisk. By default Rebel 9 looks for databases in the directory REBEL9\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/NT you can delete the readonly flag by starting the File Manager (or Explorer under Win95 and NT 4) and selecting all three files of the Rebel database (i.e. database.dat, database.ix1 and database.ix2 in the above example). The open the menue 'File' and choose the option 'Properties' in the appearing bix deactivate the readonly flag.
Rebel 9 Bonus CD
There exists at least two ways of importing ChessBase files into a Rebel database:
Export to PGN in ChessBase
Using Rebel's TB.EXE utility
Rebel databases can be joined (append a Rebel database to another one) with the freeware utility program import.exe.
In 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.
Enter the desired player's name in the "blackname=" field and enter score="+".
The "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"
Fred van Engen wrote a DOS based Rebel to PGN database converter. With this utility you can convert the Rebel database files into PGN files.
