Calling AS400 RPG Programs using C#

Throughout last few months i had a chance to work with AS400, Equation APIs. The purpose of these equations calls are that we have to develop WCF services on top of these API calls. These calls will be consumed by the BizTalk. Initially it was too hard as i couldn’t find any resources online. When i searched in gOOgle about the errors which come across at the time of developments, it does not return anything! It was some hard times and thank for my team lead for helping out on those situations. Hope to write something about  AS400, C# in coming days…

What is an AS400?

The AS/400 (Application System/400) was introduced by IBM on June 20th, 1988. Some of AS400 models are designed as Servers, while others are used as terminals or “display stations”. OS400 is the operating system for the AS/400.

In October of 2000, IBM rebranded the AS/400 and announced its name as the IBM iSeries 400. AS400 uses RPG (Report Program Generator) as its own programming language. Initially the RPG originated as a report-building program used in DEC and IBM minicomputer operating systems and evolved into a fully procedural programming language.

Here is the lovely interface of Equation.
