DASD Billing › Billing Rates › Computing the Billing Charge

Computing the Billing Charge

As each volume is scanned, its matching category code is retrieved from member DSBCATEG. This code is then used to find the proper rate in member DSBRATEC. Each data set's allocated space and billing period are computed, the rate is applied, and the result is added to the accumulating charge. These charges are stored and updated for each individual data set. The records are placed in the DASDSPCB subfile of the files data set. The VTOC SCAN and ACCUMULATE runs can be executed as often as needed to achieve the data set sampling required.
