TSO Charges

1. The Total Charge is calculated as:

   Total Charge = Processor Charge + I/O Charge
                  Connect charge +
                  UR Charge
   

2. The Processor Charge is computed as follows (same method as for batch):

   Processor Charge = Processor Time x
                      Adjusted Rate
   

3. Processor Time is calculated as follows:

   Processor Time = (Active Time x
                    Active Time Factor) +
                    (Total CPU Time x
                    Total CPU Time Factor)
   

4. The Adjusted rate is computed the same as described earlier for batch.
5. The I/O Charge is calculated the same as described earlier for batch.
6. Connect Charge for TSO sessions is computed as follows:

   Connect Charge = Connect Time x
                    Connect Time Factor
   

7. The Unit Record Charge allows for chargeback against terminal activity. It is computed as follows:

   UR Charge = ((TPUTS x TPUT-TGET-Rate) +
                (TGETS + TPUT-TGET-Rate)) / 1000
