Options

ALL

Modifies all the resource table records in the result set. When you specify ALL, the COUNT option is ignored.

BACKWARD

Modifies the previous resource table record and continues in a backward direction through the result set modifying as many records as the COUNT option specifies.

Note: If the record pointer is at the bottom of the result set, using BACKWARD modifies the current record (which is the last record) and then continues on to previous records.

COUNT(data-value)

Specifies the number of resource table records to be modified. If you do not specify the COUNT option, only one record is refreshed.

If you do not specify the FORWARD or BACKWARD option, the modification process moves in a forward direction through the result set.

CURRENT

Modifies only the current resource table record. When you specify CURRENT, the COUNT option is ignored.

FILTER(cpsm-token)

Identifies a filter to be used for this operation. The FILTER option indicates that only those resource table records that meet the specified filter criteria should be considered for modification.

The number of records that are modified is determined by the COUNT option. If you do not specify the COUNT option, only the first record that meets the filter criteria is modified.

The cpsm-token value that identifies a filter is returned by the SPECIFY FILTER command.

FORWARD

Modifies the current resource table record and continues in a forward direction through the result set modifying as many records as the COUNT option specifies.

LENGTH(data-value)

A fullword value that specifies the length of the MODIFY buffer.

Note: The buffer length you specify should not include any data other than a modification expression.

MARKED

Indicates that only those resource table records that are marked in the result set should be considered for modification.

The number of records that are modified is determined by the COUNT option. If you do not specify the COUNT option, only the first record that is marked is modified.

You can mark resource table records by using the MARK and UNMARK commands.

MODIFY(data-area)

Identifies a buffer containing the modification expression to be used in modifying the resource table records.

For details on how to form a modification expression, see Developing CICSPlex SM applications.

NOREFRESH

Specifies that the resource table records in the source result set should not be refreshed. The records reflect the status of the resources before the SET command was processed.

If you do not specify the NOREFRESH option, the resource table records are refreshed to reflect the resource status after this operation is complete.

NOTFILTER(cpsm-token)

Identifies a filter to be used for this operation. The NOTFILTER option indicates that only those resource table records that do not meet the specified filter criteria should be considered for modification.

The number of records that are modified is determined by the COUNT option. If you do not specify the COUNT option, only the first record that does not meet the filter criteria is modified.

The cpsm-token value that identifies a filter is returned by the SPECIFY FILTER command.

NOTMARKED

Indicates that only those resource table records that are not marked in the result set should be considered for modification.

The number of records that are modified is determined by the COUNT option. If you do not specify the COUNT option, only the first record that is not marked is modified.

You can mark resource table records by using the MARK and UNMARK commands.

NOWAIT

Returns control to your program as soon as the SET command has been accepted, which allows the command to be processed asynchronously.

If you specify the NOWAIT option, you must use a subsequent RECEIVE command to test for the completion of this request. The results of an asynchronous request are returned as ASYNCREQ resource table records. For a complete description of asynchronous processing, see Developing CICSPlex SM applications.

Note: If you specify the TOKEN option, the NOWAIT option is assumed by default.

POSITION(data-value)

Modifies the nth resource table record in the result set. When you specify POSITION, the COUNT option is ignored.

This value must be a number that identifies the record's relative position in the result set. The first record in a result set is identified by the number 1.

For example, to modify the fifth resource table record in a result set, you would specify POSITION(5).

REASON(data-ref)

Names a variable to receive the fullword reason value returned by this command.

RESPONSE(data-ref)

Names a variable to receive the fullword response value returned by this command.

RESULT(cpsm-token)

Identifies the API result set to be processed by this operation. The result set can be one produced by any of these commands:

• COPY
• GET
• GROUP
• PERFORM OBJECT

THREAD(cpsm-token)

Identifies the API thread to be used for this operation. The cpsm-token value that identifies a thread is returned by the CONNECT command.

TOKEN(data-value)

Defines a 1- to 4-character token that you choose to correlate an asynchronous SET request with the result of a subsequent RECEIVE command. This token is for use by your program; CICSPlex SM makes no use of the value. The token is returned by the RECEIVE command when this SET request is complete.
