Attributes, Defaults, and Null Values
Descriptions of simple tokens in this section do not identify their token numbers. 
However, the symbolic names of the token numbers can be derived from the token 
names by simply replacing -TKN- with -TNM-. For example, the token number of the 
ZSPI-TKN-MANAGER token is ZSPI-TNM-MANAGER.
The syntax boxes do not include the SPI header tokens, which are always present in 
every command and response buffer. Table 5-4 lists the header tokens that can be 
queried using SSGET in response buffers and, in some cases, changed with SSPUT in 
command buffers.
For descriptions of these tokens, refer to the SPI Programming Manual and to the 
section on SPI standard definitions.
Attributes, Defaults, and Null Values
Many command/object pairs have tokens that describe the object attributes.  Some 
attributes are required; others are optional. The programmatic interface does not provide 
any defaults.  Required values must be supplied by whatever software programs use the 
programmatic interface.
The token descriptions for each command state whether each token (or field of an 
extensible structured token) is required or optional, what its ranges or possible values 
are, and what its defaults are, if applicable. Each required field of an extensible 
structured token must be assigned a value other than its null value. Optional fields can 
also be assigned a value other than the field's null value, but this is not required.
