opset/4—modify the action and arguments of an operation of an event

The opset/4 function modifies the action and arguments of an operation of an event. The syntax for this function is as follows:

opset($EVENT,$SEQNR,$ACTION,$ARGS)

opset/4 arguments

Argument	Mode	Type	Description
`$EVENT`	Input	OBJECT	Specifies the event for which an operation is to be modified
`$SEQNR`	Input	INTEGER	Specifies the sequence number of the desired operation
`$ACTION`	Input	STRING	New action name of the operation
`$ARGS`	Input	STRING	New arguments for the operation action

Use the opset/4 function to replace the action name and arguments of operation $SEQNR that is attached to event $EVENT. The action name is replaced with $ACTION, and the argument list is replaced with $ARGS.

Operations are numbered, starting from 1 for the oldest operation. The most recent operation can be obtained by indicating 0 as the sequence number $SEQNR.

To determine the number of operations attached to an event, see opcnt/2—count the operations of an event.

Note

The time stamp and author of an operation cannot be modified.

opset/4 example

opset($E,0,'CloseEvent','');
