Mel Beckman has written an article that repeats a theme I’ve seen since the days when I first started writing code in the first widely used version of RPG in the 1970’s. There’s always a variant of RPG is dead, RPG is dying, RPG is fading away, and all that. But I always pay attention, because all things change in this world below on here on Earth. It seems like the main reason he says this is that, according to him, not much new code is being written in the newest version of RPG-IV and that most of the time spent doing RPG is on maintaining existing RPG code, as in fixes, enhancements, and the like.

I’m glad iprodeveloper opens it articles up for comments. For web sites that open up for comments so readers can offer their reactions, I’m finding these days that the comment section gets at least as interesting as the article itself. Actually, the article plus the comments generally make good reading.

For example, Mel Beckman listed a lot of other languages as newer and more promising for writing new code. He gives examples he calls “more-modern” languages: “More-modern languages such as C (including C++ and C#), Java, JavaScript, Perl, PHP, Python, and Ruby (all of which run natively on IBM i)”.

Aaron Bartell pointed out that for a some of these you have to have multi-layered implementations to make them work, with the extra load of maintaining and configuring each layer. Someone else pointed out that training current staff (the ones that know your business) in new languages is not cheap either.

I’ll add my own observation that each layer of technology -hardware, third-party software, external servers and applications, and so on– comes a multiplier in maintenance load.

Jon Paris added his observation that for one of his recent classes he was teaching the newest RPG, RPG-IV, to programmers that code in C, C++, Java, and others. He also added that the Java programmers are delighted with the ease of performing some functions in RPG.

Well, one more thing. The current generation and latest versions of RPG, RPGLE or RPGIV, have incorporated great advances that utilize, or enable the use of new techniques and possibilities. And while it does not have object-oriented syntax, with the intelligent use of subprocedures and service programs, it does enable advantages that are generally associated with OO programming.

Here’s an alert to utility software providers: there just might be a market for a precompiler that does OO things, that for example expands an embedded OO syntax into RPG code for compiling, similar to how the 4GL’s are said to work.

There are some programmers where I work who do new coding in COBOL, too.. Nothing wrong with that for the purpose, depending. But more on that later, and on refactoring code in a future article.
