AM3270 Management Programming Manual

ELEMENTS OF SPI MESSAGES FOR THE SUBSYSTEMS

Constructs Involving Multiple Tokens

The AM3270 subsystem supports two kinds of constructs that

involve multiple tokens: data lists and error lists. For the

AM3270 subsystem, these constructs are found only in responses

from the subsystem. A data list begins with the token ZSPI-TKN-

DATALIST, while an error list begins with the token ZSPI-TKN-

ERRLIST; both end with the token ZSPI-TKN-ENDLIST.

A data list is used in a response to enclose information about

one object or, in some cases, a related group of objects.

An error list is used in a response to enclose information about

an error or warning.

For details on these two constructs, refer to the

Distributed

Systems Management (DSM) Programming Manual

Components of a Command, Response and Event

For general information about components of a command, response,

or event message, refer to the

Communications Management

Programming Manual

For information on the tokens associated with each AM3270

command, response or event message, see Section 6, "Commands and

Responses," and Section 7, "Event Management," in this manual.

For information about consideratins for building and retrieving

SPI buffers, see Section 4, "SPI Programming Considerations for

AM3270."
