For all possible executions of this location: |R| = card{100} = 1 |D| = card{100} = 1 Hence: DRDR = R D = 1 1 = 1 As far as implementation of an automated system to capture the DRDR for program locations is considered, all that is required is the insertion of statements before and after each location to record the appropriate values of data objects in some file or files.	cache/ajis02-139.pdf	txt/ajis02-139.txt
