1  DELETE
 

2  KEY
   Removes a specified key from the OpenVMS Registry database. The
   system does not delete a key if the key has subkeys.  Use the
   DELETE TREE command if you wish to delete a key and all of its
   subkeys.

                             CAUTION

      Deleting a key results in symbolic links not being followed.
      This is because the system deletes the key you specify, 
      even if it has symbolic links.

                              NOTE

      The OpenVMS Registry database predefined keys are reserved
      keys and cannot be deleted. These keys are HKEY_USER, 
      HKEY_LOCAL_MACHINE, and HKEY_CLASSES_ROOT.

   This command requires the SYSPRV privilege or the REG$UPDATE
   rights identifier.

   Format:

     DELETE KEY  key-path key-name
 

   key-path

   Specifies the key path.
 

   key-name

   Specifies the name of the key to delete.
 

3  Qualifiers

/WAIT

   /WAIT=seconds (default = 90)
   /NOWAIT

   Specifies the maximum amount of time, in seconds, that you are
   willing to wait for command completion.  If the Registry server
   does not complete the request in the specified interval, REG$CP
   returns REG-F-NORESPONSE. The default interval is 90 seconds. 
   /NOWAIT is equivalent to specifying /WAIT=0, but there may still
   be a short wait period. 

/WRITEBEHIND

   /WRITEBEHIND 
   /NOWRITEBEHIND (default)

   Specifies when the information can be written to disk.
   /WRITEBEHIND specifies that the information can be written to
   disk later. /NOWRITEBEHIND specifies write-through operation
   (that is, the information must be written to disk immediately).
 

3  Example

       REG> DELETE KEY HKEY_USERS\NODE GUEST

     Deletes the GUEST key from the OpenVMS Registry database.
 

2  VALUE
   Removes a value from a specified key.

                                CAUTION

      Deleting a value results in symbolic links not being
      followed. This is because the system deletes the value 
      you specify, even if it has symbolic links.

   This command requires the SYSPRV privilege or the REG$UPDATE
   rights identifier.

   Format:

     DELETE VALUE  key-name value-name
 

   key-name

   Specifies the key name whose value should be removed.
 

   value-name

   Specifies the value to remove.

2 TREE
