RPG decidedly not dead, say Search400.com readers

On June 29, 2009, many Search400.com readers received an email that got them a little stirred up. I sent out our newsletter and presented an article on EGL and a blog on RPGAAS. This is what I wrote:

So is EGL the new high-definition, flat-screen replacement to that old vacuum-tube television? Is RPG really that outdated? Is there a dearth of RPG programmers available, requiring shops to consider the RPGAAS offering? I ask for reader input partly out of sheer curiosity but also out of a desire to serve the informational and educational interests of readers. If RPG is outdated, what do you need to know about instead? Send me your feedback.

Eleven readers were compelled to write back, and not too surprisingly, none of them sung the praises of the fall of RPG. Instead, most made ardent defenses of RPG as a useful and necessary programming language.

I don’t believe RPG is outdated. It has become much more like a scientific language since the introduction of procedures, local variables, and pointers. ILE makes reusability easy, with modules and service programs. RPG seems like a very relevant language and I enjoy it. If there are people suggesting that RPG is outdated, why do they say so?

First, let me say that I reject the argument that there is a dearth of RPG programming talent available. This argument fails to understand the dynamics of supply and demand market forces. There is a dearth of RPG positions available to skilled RPG programmers. Don’t believe it? Post a job opening for an RPG programmer offering a competitive salary with benefits; I promise you, within hours you will have a pile of resumes to choose from. I personally know of several traditional RPG programmers who are currently either looking, or have “settled” for other work.

AS/400 shops stopped hiring after Y2K for a number of reasons, but a scarcity of programming talent was not one of them. Younger people who were educated in the 80’s and 90’s on Wintel platforms – and, in some cases, on Unix and Linux, because, after all, that’s what they learned on in college – moved into decision making positions, and lacked a fundamental understanding of what the IBM midrange platform was doing for the organization. [They] made strategic decisions to move off the platform onto newer, sexier platforms that were graphic and Web-enabled, and which made them feel more comfortable. They walked through the organization and saw all these green text-based screens, and wondered why their internal platform wasn’t capable of colorful graphics and Web-based applications that communicated to their customers and supply chain? And when they questioned their staff as to why those kinds of apps were not available, they got answers ranging from “IBM doesn’t support that” or “it’s expensive and difficult to do” on an AS/400-based server. Which is far from the truth …

I personally know of an AS/400 shop who has Web-enabled all of their internal, home-grown applications. Remote locations were able to ditch expensive frame-relay communication networks in favor of DSL lines into each of their 50+ remote locations, domestic and international. Was it expensive? It was, in fact, a fraction of the cost of moving off the AS/400 platform onto something Windows-based, rewriting legacy apps, and installing and maintaining all new Windows-based hardware and networks.

If there is a dearth of anything, it is in ISV’s offering native ERP solutions to businesses. There are a dwindling number of solutions providers who have stayed with the platform; most have developed comparable, competing apps using .Net or other development tools. RPG programmers have had to learn Java, .Net, or now PHP in order to remain employed. Rational tools? EGL? It’s all just additional buzzwords to facilitate IBM’s move away from RPG. IBM sees the writing on the wall, all these young decision-makers wanting graphic and Web-enabled interfaces. So instead of placing development emphasis on making RPG-based apps more modern – perhaps by offering a native CGI for RPG – IBM moves businesses away from the platform, away from the strength of all those legacy apps written in RPG that drive business logic, to newer platforms, newer tools, newer apps written in languages that didn’t exist a decade ago. And probably won’t exist a decade from now. Which means, for businesses who invest in them by developing business logic apps, another conversion, another migration, a decade or so down the line …

Furthermore… vLegaci’s … “RPG as a Service” is nothing more than out-sourced contract development with a new name. A pig is still a pig, and calling it something different don’t make it so. I don’t buy into it as even remotely related to “cloud computing” a.k.a. capacity on demand.

Welcome the new iSeries blog location on IT Knowledge Exchange

Hi readers,

We’ve moved our blog to IT Knowledge Exchange to take advantage of some of the features this site has. Some of these features are pretty neat, but I know that “change is hard.” So, let me tell you about a few of the new features. First, instead of a long list of categories, we now have a Tag Cloud. Click any topic in the Tag Cloud and you’ll see only posts on that topic. The Tag Cloud is dynamic, so the more a tag is used, the larger and darker it will appear. This helps you quickly see the most popular topics.

You’ll also notice we’ve integrated more of our related editorial content in the right sidebar. If you’re on a post about a specific topic and wish to know more after reading the post, be sure to browse the links in the right sidebar.

We always appreciate your sharing our content on social networking sites and we’ve increased the number of bookmarking tools from four to forty-three. If you enjoy a post, please be sure to share it with friends and colleagues.

Look near the top of the page and you’ll see a row of tabs. You can click the IT Blogs tab to find dozens of technology blogs, both user-generated and TechTarget editorial blogs. You can even request your own blog and start sharing your expertise with your peers.

There is also a tab labeled IT Answers. This is where you can ask your own IT question and have it seen by thousands of IT Knowledge Exchange members. So be sure to pose your own AS/400 questions, and browse thousands of answers or help out a fellow IT pro by answering a question.

Thank you for stopping by and be sure to bookmark our new blog location and visit the AS/400 section on IT Knowledge Exchange.
