In each case, for z/OS and UNIX client systems, the example presumes that a table named TranLogTable has been created on a database as follows:
CREATE TABLE TranLogTable (TranDate Date, Region Char(3), CustNo Char(12), OrderNo Char(6), ProdCode Char(8), Quantity Integer, Price Integer) Unique Primary Index(OrderNo, ProdCode);
The Windows examples are presented differently.
