19. User Files

The program creates a subdirectory molmol in the home directory of the user, and stores some files there:

history: The command history of the last session. This can be executed as macro (command XMacUser).
dump: A binary file that describes the complete program state. This file is written whenever the user quits the program, and it is automatically read on startup. It is recommended to remove dump (or move it to a different name) before starting work with different molecules.
par: Contains values of some program parameters. These values are also stored in the dump file, so it is redundant if a dump exists. It is used to maintain preferred parameter values of the user when the dump is removed.
