Multirecord Responses

Figure 2-8 shows how a requester returns response records when the MAXRESP

header token is allowed to default to 0. Only one response record is returned in each

response message, and this record in not enclosed in a data list. If the command is

applied to more than one object, each response record is returned in a separate

response message, each but the last of which includes the context token, following the

standard protocol for command continuation.

The server returns one response record in each response message. Response records are not

enclosed in data lists.

Example: MAXRESP = 0 and one object qualifies for processing:

The server returns one message containing one response record (not in a datalist).

Example: MAXRESP = 0 and five objects (a through e) qualify for processing:

H Ra T1a T2a C

H Rd T1d T2d C

H Rb T1b T2b C

H Rc T1c T2c C

H Re T1e T2e

The server returns five messages, each containing one response record (not in a list).
