 The following command deletes a physical RMS database, EMP_FILE, which
 is stored in the RMS file EMP.DAT.  Notice that the DELETE DATABASE
 command without the /LOG qualifier gives you a message that only the
 physical file EMP.DAT is deleted.

 In the following example, DELETE DATABASE/LOG gives you an additional
 message that the CDD$DATABASE entity SSG_FILE is deleted from the CDO
 dictionary as well as the physical file EMP_DAT:

 CDO> DELETE DATABASE/LOG SSG_FILE.
 deleting file USR02:[MCGUIRE.RDB]EMP.DAT;, proceed? [Y/N] (N)y

 The name of an RMS database definition.

 You can only delete an RMS database definition from the dictionary when

 must delete all physical RMS databases that use an RMS database
 definition before you can delete the RMS database definition from the
 dictionary.

Additional information available:

/LOG

 /LOG
 /NOLOG (default) Controls whether or not an informational message is
 displayed on the terminal screen that the CDD$DATABASE entity has been
 deleted from the CDO dictionary.  The default /NOLOG suppresses the
 message.

 The following example shows what happens when you attempt to delete an
 RMS database definition, EMPLOYEE_STORAGE from the dictionary, while it
 is being used by a physical RMS database on disk.  You must first
 delete the database, DISG_FILE that is using the RMS database
 definition before the DELETE RMS_DATABASE command will succeed.  When
 the DELETE RMS_DATABASE command succeeds, the CDO> prompt returns,
 unless you use the /LOG qualifier.  To verify that EMPLOYEE_STORAGE;2
 was deleted, use the DIRECTORY command.

 CDO> DELETE RMS_DATABASE EMPLOYEE_STORAGE;2.
