Set or disable autosave, which saves the XSPEC environment to a file periodically.
where <option> is either off or a non-zero positive integer N. If the option is off, then auto-saving is disabled. If the option is N, the XSPEC environment is saved every N commands. The saving of the environment is equivalent to the command
XSPEC12>save all xautosav.xcm .,
i.e. both the file and model information is saved to the file xautosav.xcm,
placed in the directory /.xspec/cache. Thus in case of an unexpected crash,
the state of XSPEC before the crash can be restored by running @xautosav.xcm.
The default value for the auto-save option is 1.
