1    /CACHE_ACTION

    /CACHE_ACTION=value

    Specifies the cache attribute for the new key. The value can be
    WRITEBEHIND (write to disk later) or WRITETHRU (write to disk
    immediately).

    If you omit /CACHE_ACTION, the system creates the key with
    the cache attribute set to REG$K_WRITEBEHIND.

2    /CLASS_NAME

    /CLASS_NAME=string

    Specifies the class name of the key.

3    /LINK

    /LINK=(TYPE=value, NAME=key-name)

    Defines the key as a link to another key. The link value must be
    one of the following:

    o  SYMBOLICLINK

    o  NONE

    To remove a link, enter the following:

    /LINK=(TYPE=NONE,NAME="")

4    /SECPOLICY

    /SECPOLICY=policy

    Defines the security policy for the key. Currently the only valid
    policy is NT_40.

5    /VOLATILE

    /VOLATILE=level
    /NONVOLATILE (default)

    Specifies whether or not the new key is volatile. If you are
    running the OpenVMS Registry on a standalone OpenVMS system,
    volatile keys are lost when the system reboots. If you are
    running the OpenVMS Registry in an OpenVMS cluster, volatile
    keys are lost when all nodes in the cluster are rebooted.

    The values for level are as follows:

    o  NONE (same as /NONVOLATILE)

    o  CLUSTER

6    /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.

7    /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).
