About this document:

If you use RPG as your programming language for the AS/400 system, you can create CGI programs to work with Web forms. This article, adapted from seminar materials, describes the basic concepts of CGI processing and includes ILE RPG code samples of a complete, working RPG-CGI program. The code sample shows how to use the QzhbCgiParse API, which is a more powerful API than the obsolete QtmhRdStin and QtmhCvtDb APIs.

The sample is available in RPG only. I do not have a sample available for COBOL.

The sample is available as RPG source code only. Please do not ask me to send you a compiled version of the program. If you do not know how to compile the programs, seek competent help. If you do not have the AS/400 RPG compiler, you will need to locate an AS/400 that has the compiler.

RPGCGI.htm - Web page that describes how to use CGI APIs in an ILE RPG program.

RPGCGIPPT.htm - PowerPoint Web presentation that describes how to use CGI APIs in an ILE RPG program.

You can then navigate through the slide show by clicking each slide in order.

Download Files:

Note: you can view the files in your browser by clicking the link. To save the files, right-click and select the "Save Target As..." option.

testcgi_html.txt - HTML file for test name and address form. Save this file, copy to a directory on your AS/400 IFS to test the RPG-CGI programs.

testcgi.txt - ILE RPG program that produces a response Web page. Calls the CGIPARSE program.

cgiparse.txt - ILE RPG program that calls the QzhbCgiParse API to parse the contents of the POST buffer. Returns results to the caller in two arrays (field names, field values). This is a general purpose program that you can call from any program that needs to process an incoming POST buffer and parse field name/value pairs.
