Subsystem ID

A 6-word (12-byte) structure that uniquely identifies a subsystem:

Command Number

A 16-bit signed integer value (type ENUM) that identifies the command being sent to a

subsystem.

Command numbers in subsystem definition files have names of the form

subsys-CMD-name, where name identifies the command.

Object-Type Number

A 16-bit signed integer value (type ENUM) that identifies the type of object to be

operated on by a command.

Object-type numbers in subsystem definition files have names of the form

subsys-OBJ-name, where name identifies the object type.

Token

A token has two parts: an identifying code and an associated value. The identifying

code can be either a token code or a token map.

Token Code (subsys-TKN-name)

A 2-word (4-byte) structure that identifies a simple or structured token; it consists of a

token type, a token number, and an optional subsystem ID.

ZSPI-TKN-SERVER-VERSION Server version

ZSPI-TKN-SSID Subsystem ID specified in SSINIT call

ZSPI-TKN-USEDLEN Number of bytes used in the buffer

Z-OWNER 8-character string to identify the company or organization providing

the subsystem; for NonStop Kernel subsystems provided by HP,

“TANDEMbb

” where b represents an ASCII blank.

Z-NUMBER 16-bit signed integer that identifies a subsystem within the set of

subsystems provided by the owner.

Z-VERSION 16-bit unsigned integer representing the software release version of

the subsystem.

subsys-VAL-SSID The symbolic name of these three preceding subsystem ID fields for

NonStop Kernel subsystems, where subsys is a 4-character

subsystem abbreviation.
