Detail line hierarchy

An unexpanded D08 report shows a line for each DDNAME causing a delay in execution while waiting for DASD I/O activity to complete. You can expand each line to reveal additional hierarchical levels of detail (using the "+" line command).

The hierarchy is illustrated here:

Level 1 DDNAME
	Level 2 File I/O Request
		Level 3 Supervisor Call (SVC)
			Level 4 Module
				Level 5 CSECT

	Level 2 File I/O Request
		Level 3 Module
			Level 4 CSECT

	Level 2 Supervisor Call (SVC)
		Level 3 Module
			Level 4 CSECT
