Arasan automatically keeps a log of all games played during a given execution of the program. This is kept in a file called "arasan.log," which is stored in the same directory as the program. In addition to recording the game moves, Arasan records information about the search process, which you may find interesting. Normally, every time you execute arasan.exe, it overwrites "arasan.log," so if you want to save the contents of the log, you must copy it to another file after terminating the program. However, you can you can make Arasan append to the end of an existing log by changing an option in the arasan.rc file in the Arasan installation directory.
The log file is not intended for permanent storage of games. If you want to save a game so that it can be later re-loaded into Arasan and replayed, you must do so before exiting the program. Select the "Save Game" selection from the File menu and Arasan will prompt you for a file in which to store a completed game. Games stored in this way are written in a format called Portable Game Notation (PGN), which is a standard for exchange of chess games used by several different chess programs.
A game stored in PGN notation may be read into Arasan by selecting File Open and choosing a file with .PGN extension. If there is more than one game in the file, Arasan will provide you with a list to choose from. Once Arasan completes reading in the file, you can replay the moves by typing "^F" (Control-F) or clicking on the right arrow icon on the toolbar.
It is also possible to store an individual board position. You may want to do this if you are in the middle of playing a game and want to resume it later. To save a board position, select "Save Board" from the File menu. You will be prompted for a file name to save the board to. Board positions are stored in Forsythe-Edwards notation (FEN), which is a standard used by several chess programs.
To retrieve a previously stored board position, use the File Open command and select the .FEN file that you previously saved.
