## Workstaton E/C/D, Remote data access The applications for this scenario can be CICS or batch programs accessing host data. (CICS programs possibly accessing DB2 databases or VSAM files; batch programs possibly accessing any the data shown in the picture.) Examine the distribution of the tasks between the host and workstation, the benefits of this scenario, and the costs to set it up.
Which Tasks are Done Where "X" indicates the primary platform
Task | Host | WrkS
--- | --- | ---
Edit programs on the workstation. Download the program files from the host to a COBOL project and edit. |  | X
Compile the programs. Compile even programs using CICS and DB2 on the workstation by using the the CICS pre-processor and DB2 co-processor. As needed retrieve COPY files from PDS datasets from the host. Using host data type support, there is no need for file conversions when accessing host data. |  | X
Debug the compiled programs. Execute on the workstation with the full-function debugger, accessing host data remotely. |  | X
Compile the production programs Do a final compile on the host to create the production host application. | X |
Conduct the system test using your standard setup Use your existing test procedures for the host system test. | X |
Notes
Benefits
Be more productive with your editing tasks with the language-sensitive VisualAge COBOL editor. It parses the source as you enter it, giving a visual presentation. The learning curve is not as steep as you might think: the editor is customizable and can be made to look and feel like your favorite editor while retaining all the strengths of a workstation editor. Save time: compile-time error messages appear right in your edit session following the line on which the error occurred. Create your application fully on the workstation by using the co- and pre-processors. Organize even complex applications into project hierarchies and get a visual perspective of how your code is organized. Avoid the need for conversions by using VisualAge COBOL's host data type support when accessing host data. Ease your debugging using a GUI with interactive debugging fully on the workstation. Do a full development cycle on the workstation with data accessed remotely. Get great turn around; no waiting in queues for your jobs.
Costs
Source files need to be downloaded and uploaded (for production). COBOL projects need to be defined to reflect the host application organization Network traffic will increase. Host systems programmers need to be involved for configuration of the communications.
