This example will use a COBOL program with embedded SQL to create a table with an index. This example includes a JCL member and a Windows CMD file. In the world of programming there are many ways to solve a problem. This suite of programs is provided as a COBOL programming example of one of the possible solutions.
The following is the Windows Command file (ITQCT1E1.CMD) that is required to run as a job on a PC using Micro Focus Net Express.

This program is one of a suite of programs that provide for converting a VSAM, Keyed-Sequential-Data-Set (KSDS) to a Relational Data Base. The complete Z-Pack may be downloaded from http://www.simotime.com/sim4dzip.htm#ZipsforSQL or view the complete list of SimoTime Examples at http://www.simotime.com/sim4dzip.htm.
Note: You must be attached to the Internet to download a Z-Pack or view the list.
Check out The SQL Connection for more examples of mainframe Relational Data Base management and accessing techniques with sample code.
The example for Insert a Row uses embedded SQL in a COBOL program to insert data into a table of an existing data base.
The example for Update Table Information uses embedded SQL in a COBOL program to update data in an existing row or insert data into a new row using a unique primary key.
The example for Sequential Processing uses embedded SQL in a COBOL program to insert data into a table of an existing data base.
The example for Delete a Table uses embedded SQL in a COBOL program to delete a data base for the item information.
