HP NonStop™ Kernel operating system. The operating system for HP NonStop systems.
HP NonStop™ Kernel user ID. A user ID within an HP NonStop system. The Guardian 
environment normally uses the structured view of this user ID, which consists of either 
the group-number, user-number pair of values or the group-name.user-name 
pair of values. For example, the structured view of the super ID is (255, 255). The 
Open System Services (OSS) environment normally uses the scalar view of this user 
ID, also known as the UID, which is the value (group-number * 256) 
+ user-number. For example, the scalar view of the super ID is (255 * 256) + 255 
= 65535.
