Token Codes
ZSPI-TKN-COMMAND
ZSPI-TKN-COMMAND contains the command number. This value is set by SSINIT
and can be retrieved using SSGET. This value cannot be modified using SSPUT.
ZSPI-TKN-COMMENT
ZSPI-TKN-COMMENT is a token that a requester can use to include arbitrary
information of its own in a command. NonStop Kernel subsystems ignore this token
and do not return it in responses. Its token type is ZSPI-TYP-STRING. Its value is a
variable-length character string. The buffer sizes recommended by NonStop Kernel
subsystems allow for one 80-byte comment token in every command.
ZSPI-TKN-CONTEXT
ZSPI-TKN-CONTEXT is a special token that indicates (by its presence or absence)
whether or not there are more objects to process. If this token is present in a response,
the response can be continued in another response message; if it is absent, this is the
last response message. The token value provides information needed by the server to
determine where to resume processing. The requester should ignore the token value,
but must send the token back to the server in a copy of the original command
message. For more information, see Section 2, SPI Concepts and Protocol
.
The token type of this token is ZSPI-TYP-BYTESTRING.
