Use FILE when you want to save changes to a file permanently and quit editing
the file.

Use QUIT to quit editing a file you have not changed. If you have made any

DMSXSU577E File has been changed; type QQUIT to quit anyway

Use QQUIT to quit a file and not save any changes you have made since the last
save. The subcommand is handy if you decide you do not want any of the
changes you have been currently making or if you want to be sure you have not
changed a critical file.
