## Workstation E/C/D, LAN data access The applications for this scenario can be CICS or batch COBOL programs possibly accessing DB2 or VSAM files. 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 the LAN 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 access COPYBOOKS from the LAN. |  | X
Download/create data Transfer host data to the LAN or create test data on the LAN. | X | X
Debug the compiled programs and test the application. Execute on the workstation with the full-function debugger, accessing LAN and workstation data from the same application. |  | X
Compile the production programs Do a final compile on the host to create the production host application. | 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 firing up the co-processor.
- Organize even complex applications into project hierarchies and get a visual perspective of how your code is organized.
- Eliminate host access by downloading data to the LAN.
- You can do a full development cycle on the workstation.
- Ease your debugging using a GUI with interactive debugging fully on the workstation.
- Reduce host CPU usage.
- Get great turn around; no waiting in queues for your jobs.

Costs

- Source files need to be downloaded and uploaded (for production).
- All required test data must be transferred to or created on the LAN.
- COBOL projects need to be defined to reflect the host application organization.
- LAN administrators need to be involved for configuration of the LAN.
