	Indicates that a task is in transition to the WAITING-SUSPENDED state.
	Indicates that a task is in transition to the DORMANT state.
	Indicates that RI850V4 processing was executed in association with the issued service call.
	When "processing program" has been selected in the Analysis information table area, this color indicates the processing interval that was executed first among the intervals shown by . Pressing the Toolbar buttons ( , , etc.) moves to the corresponding processing interval.

In this area, usage status of the real-time OS resource is indicated with the event marks below:

	Indicates that a service call has been issued. When the mouse cursor is placed on this mark, the "service call name" (ID number of the object) for which a service call is issued.
	Indicates that a service call has been terminated normally. When the mouse cursor is placed on this mark, "E_OK (0)" appears indicating normal termination of the service call.
