ELEMENTS OF SPI MESSAGES FOR THE EXPAND SUBSYSTEM
Other Tokens
Extensible structured tokens do not appear in any event message
or error list issued by the EXPAND subsystem.
Throughout this manual, when an extensible structured token is
described, its DDL definition, including the definitions and
types of all fields, is also given.
The predefined field values used by the EXPAND subsystem are
represented by symbolic names of the form subsys -VAL- name ,
where subsys is a four-character subsystem abbreviation and name
identifies the predefined value.
A table of all the token maps defined by the EXPAND subsystem
(token maps with names of the form ZEXP-MAP- name ) can be found in
Appendix B.
Field Types
All the field types used by the EXPAND subsystem are SPI standard
field types, so they are represented by symbolic names of the
form ZSPI-DDL- name , where name identifies the field type. For
example, the field type ZSPI-DDL-BOOLEAN represents the Boolean
data type.
Throughout this manual, when a field is described, its field type
is given.
Constructs Involving Multiple Tokens
The EXPAND subsystem supports data lists and error lists as
described in the Distributed Systems Management (DSM) Programming
Manual .
Components of a Command
This topic is discussed in the Communications Management
Programming Manual .
Each EXPAND command and the tokens it contains are described in
this manual in Section 7, "Commands and Responses."
Considerations for building EXPAND command buffers are described
in this manual in Section 5, "SPI Programming Considerations for
the EXPAND Subsystem."
