CATBOOK ("Captain's Logbook") is a "collection database" for documenting your DX history (= your QSLs, loggings, audio clips, etc).
Every row (station) in CATBOOK is connected to a user-specified color code called P-TAG (see P-TAGS for details). This tag is added to all stations that are saved in CATBOOK, and they are used to define how the station will appear not only in CATBOOK but also on the standard MAPS and TURTLE displays.
CATBOOK is created automatically when you make the first logging / offset logging. Then a new station is added automatically to CATBOOK when it is logged; also other JAGUAR functions can be used to add stations to CATBOOK.
The CATBOOK file itself is a simple text file ("CATBOOK.txt"), and it is located in the JAGUAR installation folder. However, it is not recommended to edit this file manually usind Notepad etc because data in wrong column positions can easily corrupt the file.
You can open the CATBOOK database from DATABASE BAR: move the mouse over the center area and click the CATBOOK button.
You can also press ALT-T repeatedly to rotate TURTLE > USA TIS > CATBOOK > KOJE > MWLIST.
CATBOOK stays mostly "out of sight"; it just serves as a background data source for several JAGUAR displays.
At the moment, there are no tools for converting your old documentation (QSL statistics, etc.) to the CATBOOK format, but there are tools for quick setting of the color code for a bunch of stations (see STATION MENU > TAGGER for more information) and this way you can easily copy a large amount of stations from TURTLE to CATBOOK.
