1. Unless you are creating a VB file , the length of all records in a FB are of same length. For a VB file move the length you want into the 1st bytes of RDW.

2. Depends on how the table is defined and sorting algorithm you use.

3. JCL DD override as long as the pvt dataset is also on the same LPAR

4. Query the catalog tables

5. After the completion of A, both B and C run in parallel.
