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.

How to create a CGI program

Net Express contains all the tools you need to create CGI-based applications in COBOL. Internet Application Wizard Create three flavors of

internet application: Create HTML pages and forms and server-side programs to

access relational databases over the Internet or an Intranet. Turn a COBOL subroutine into an Internet application

instantly. Create a skeleton server-side program using pages and

forms from Form Designer.

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: Existing COBOL programs SQL databases HTML forms (designed with Form Designer in Net

Express)

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.

The Parameter Assignments 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.

Presentation Title HerePresenter’s Name Here

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.

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.
