3. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada The Common Gateway Interface One of the longest-established methods of writing an application for the Internet or an intranet is the server-side program. Server-side programs are often known as CGI programs, or simply CGIs.

4. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada How to create a CGI program Net Express contains all the tools you need to create CGI-based applications in COBOL. n Internet Application Wizard Create three flavors of internet application: l Create HTML pages and forms and server-side programs to access relational databases over the Internet or an Intranet. l Turn a COBOL subroutine into an Internet application instantly. l Create a skeleton server-side program using pages and forms from Form Designer.

5. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada Internet Application Wizard Reduces the amount of effort involved in creating server-side programs and associated HTML forms. Server-side programs can easily be generated from: n Existing COBOL programs n SQL databases n HTML forms (designed with Form Designer in Net Express)

6. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada Highlights of the Wizard Where necessary, the Internet Application Wizard generates the HTML forms to accompany the server-side program. All the generated files can be automatically added to the current project. You can create applications for use with CGI (supported by all Web servers). When you have created an application with the wizard, you can use it as it is or you can modify the forms with Form Designer and extend the COBOL source code.

15. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada The Demonstration The Parameter Assignments n The Parameter Assignments page of the Internet Application Wizard enables you to assign different types of form controls (radio buttons, checkboxes, text input etc.) to parameters in the Linkage Section of your COBOL program.

16. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada The Demonstration For each COBOL parameter that is represented on an HTML form, set the type of control that should represent it. For each COBOL parameter, specify whether the relevant form control should appear on the input form, the output form, both or none. You can do this by clicking in the appropriate row of the I/O column and selecting from the entries in the drop-down menu. You can set the I/O column for all the parameters in a group by right-clicking on the group item in the tree view and clicking In, Out, Both or N/A on the popup menu. All subitems inherit the group item setting.

18. Presentation Title Here Presenters Name Here GDT 2007 International User Conference: Evolving the Legacy July 29 – August 1 Lake Las Vegas, Nevada The Demonstration The Internet Application Wizard has now created all of the programs and web pages that are needed to run the web application as a CGI. Generally the CGI is now ready, but since we are needing to run this in the GDT environment we have to do some more steps.
