|0||If 1, enable new naming.|
|1||Must be 0. This bit is Reserved for use by VSI.|
|2||If 1, cloned device unit numbers wrap after 9999(not 65472).|
|3||If 1, cloned device unit numbers wrap after 32767(not 65472).|
Even if both bits are zero, device unit numbers will wrap after 9999 if "nodename$" is prefixed to the name of the device in question (e.g. VMS123$DKA100:); devices whose drivers support larger device numbers will wrap after 65472 (or 32767 if bit 3 is set) only if the nodename is not built into the device name.
