back to article An open-source COBOL contender emerges

The newly announced gcobol compiler is a fresh front end for GCC, and builds native binary executables. There are already other FOSS and freeware compilers for COBOL out there, but few are fully open source. Notably, there's GnuCOBOL, which evolved out of OpenCOBOL. The OpenCOBOL FAQ is worth a read, and notes that: "OpenCOBOL …

        A well-known computer centre used to often run out of toilet paper and old cobol dump printouts were put in a bin to be used in such emergencies - hence the phrase - take a dump.

                1. jake Silver badge

                  In the 1890s, newspapers didn't have a drastic ink-rub problem, thanks primarily to the letterpress that they were printed on and the solvents and inks in use. It wasn't until the advent of the Vanguard Web Press in the mid 1950s that newspaper rub-off became a major issue.

                  By the 1990s, however, rub-off had been solved. In fact, the San Francisco Chronicle even advertised it's new flexographic presses with no-rub ink as a selling point in the late '80s or early '90s.

    How did it come to this?

    To read the 2014 COBOL standard, iso.org invites me to cough up 198 Swiss Francs for the privilege.

    There are too many closed standards like this. Not just software standards either - mechanical and electrical standards can only be read by those with deep pockets as well. The problem is the same with academic papers - you can identify papers from 60 years ago which are relevant to your own personal research only to find them locked behind the academic distribution mafia's paywalls. The way technical and scientific information and knowledge is published today is utterly broken.

    Far from "furthering knowledge", the distribution and publishing cartels actually slow down innovation and education. The only thing furthered is the cartel member's bank balances. The cost of access to standards, journals or research papers restricts their availability to those with business licenses or very well off citizens (if allowed).

    Access to knowledge should not be decided by how much money you have.

        A lot of the documents held hostage behind the cartel paywalls were actually created by public organisations with public money. It shouldn't even be legal to ransom these documents for the distribution cartel's financial gain.

        Still, it's a problem, and I wish more commercial software-development organizations just budgeted to subscribe to the standards relevant to their work, for all their developers. I've settled too many language-lawyer questions just because I paid (out of my own pocket) for the standards.

        For C90, back in the day, many people bought Schildt's The Annotated ANSI C Standard, which contained the complete text of C89 (the ANSI version, adopted wholesale by ISO the following year). The book was cheaper than the standard document from ANSI, but contained all of its text, plus Schildt's commentary.

        The standard review on comp.lang.c was that the cost difference was the value of Schildt's annotations. Still, you were free to ignore those.

      I could almost stomach paying for useful standards, but even worse than hiding standards behind a paywall is when they:

      * Have one standard reference three more, each of which references yet more standards.

      * Update a standard every couple of years with insignificant changes that still require obtaining the latest version.

      * have two or more standards from SAE, ISO, DIN, etc. that are pretty much the same, but aren't identical so you need multiple copies.

      At work I have access to an internal tool that gives me access to pretty much any standard I can dream of (already bought and paid for). Even relieved of the financial concerns the hassle of the above bother me.

          He did everything from AS/400 Minis to IBM-Z-series COBOL to DEC VAX COBOL mostly doing COBOL to JAVA and C++ conversions.

          He finally retired after doing the last 20 years NOTHING BUT COBOL conversions. With investments he now has quite a bit over $10 MILLION USD cash in the bank and just finally retired to his British Virgin Islands mountain luxury house to live a life of forever-more fishing and travel!

          It can be VERY PROFITABLE if you know BOTH MATH (Linear Algebra, Advanced Calculus) AND COBOL, JAVA and C++ -- New York firms are offering contracts from $500,000 per year up to $1.5 million per year if you can finish the conversion jobs as lead programmer in the time required!

          Mostly just automated FAST trading programs and trend graphing programs originally running on DEC VAXes, IBM AS/400's and IBM Mainframes and Sun Workstations/Servers of 1970's/1980's era code!

          Soooo, COBOL is NOT dead! Many cities STILL use 1960's era COBOL and FORTRAN to run their older infrastructure AND to do employee payroll and job administration! Even that low-level conversion work is $150,000 per year on contract PLUS bonuses! You have AT LEAST 10 to 15 YEARS of solid money-making COBOL conversion work just in the Northeast USA alone!

          If you want a warmer climate, Singapore and Southern Japan ALSO have probably 20 more years of COBOL conversion work for their 1980's era government computer infrastructure still left at around $200,000 USD per year salary. You'll be a really SMALL TEAM of just 1 to 5 programmers to do decades worth of work BUT it will be profitable AND you get yearly bonuses!

HTML5, CSS3, javascript with node.js, angular, react, ajax, bootstrap.js, jquery, json and PHP. I spent about a year trying to learn this shite on my own. I don't know at what point I decided this just wasn't worth it, but it just seemed to be too much 'cute' code - i.e., how much you can do in one sentence and not be obvious in your intent.

        You will note that I did *not* say "paid a ton of money", or in more modern SI-compliant terms, "a tonne of money."

        I merely said they'd be (more or less) guaranteed a job. I didn't say anything about whether it'd be a *well-paid* job.

        A chap I knew with slightly dated programming skills spent a long time looking for work after the Credit Crunch. Nothing going: nothing in C* or Delphi or anything he'd done in the 20th century.

        Then, he told me, he had a brainwave. He read about old codgers getting Y2K remediation work, and rewrote his CV to focus on the oldest language he knew: Fortran.

        Subsequently he'd been employed at full contractor rates for several years. The first role he landed accepted that he'd have to get back in practice and modernise his knowledge a bit; they were just happy to have someone who they didn't have to train from scratch.

        After that, it was renewal after renewal. Occasionally he would turn down offers if they weren't well-enough remunerated, but use the offer to get a pay bump.

        When I was hunting for sysadmin work around the early noughties, I got far more interest for knowing OpenVMS than I did for more modern systems.

      True. The reason COBOL continues to exist is largely (though not exclusively) to continue to glue together what used to be called "teleprocessing" applications.

      It's quite remarkable that, despite originating in the 1960s, being impenetrably arcane and multiple attempts by IBM to kill it off, CICS is still so widely deployed - especially at a time when so many systems are being rewritten for no better reason than to be "modern".

      Perhaps it is because it's impenetrable and arcane and no-one really knows what their legacy code actually does. In which case, having a compiler is likely to be the least of your worries - though congratulations to those who put in the effort.

        But that's a legacy code base for you. Vast landscapes of undocumented, largely comment-free source — when source is available at all. Sometimes people just have faded listings on paper. Sometimes no source code at all. No one knows exactly what operations and calculations those applications perform. Replacing them would be a major feat in software archeology.

        And why take the risk, when you can put a modern3 front end on the thing, by screen-scraping, or using an environmental mechanism like EXCI, or tacking a web API over the business logic. You get a new "user experience", management is satisfied, none of the incomprehensible tangled mess needs to be unpicked.

      Re: "guaranteed a job."

      We have plenty of COBOL customers who are not using CICS or IMS or z batch-mode environments.

      It does seem to be common to tie COBOL jobs to particular environments: "we want someone who can write COBOL for Siemens BS2000", as if people capable of working on that machine are born that way and couldn't possibly have learned it.

      That said, the COBOL standards leave ample room for major differences among implementations, and pretty much all of them have extensions. So you can't just move COBOL expertise from one implementation to another. And it's also true that real-world COBOL applications will have to deal extensively with their environments. But these are things which can be learned.

      Re: Scary

      Unlike horses or people software doesn't actually age. If it did a satisfactory job in 1960 then its going to continue to do the same job in 2060. COBOL programs in particular are a mechanization of a business process, a process that may well predate computers as we know them today, a process that might date back decades or even hundreds of years. Its possible to add to the process, improve the interfaces, extract additional information from the workflow or whatever but until the underlying process changes there's nothing to be gained from meddling with the implementation.

      That's the danger of rewriting the code in a modern language. The temptation will be to meddle with the process. This carries significant risk.

        Too many decades back I did get involved with the migration of COBOL to C (ie. when C was the fashionable language of the moment), the laugh was that the C code to do the same functionality was a mess as it tried to handle all the stuff COBOL just did. So the solution was to create libraries etc. and before you knew it, the C started looking a lot like COBOL...

        The problem COBOL and Fortran have, isn't that they are old - C is 50 this year and other more fashionable languages are middle-aged, but that they somehow gained the reputation and thus are perceived and mocked as being long in the tooth and not fit for use by "real programmers".

        The thing about business processes is that they change frequently. Businesses are about competing with others and trying to increase their revenue and profit. They will change the way they set prices, discounts, they will change the product they sell, the way that they sell them. If they don't do that then their competitors will and will take business from them. The computer systems are required to be amended to implement these changes.

        > rewriting the code in a modern language

        Back in the 80s there was a Datamation survey that reported that 80% 9or so) of COBOL programming was reported as being 'maintenance' whereas 90% of C programming was new applications. Some seemed to conclude that if COBOL programs were converted to C then the 'maintenance overhead' would disappear and the programmers would create new applications.

        The whole survey was seriously flawed. The COBOL and C sites were doing completely different types of applications. The COBOL 'maintenance' was, in fact, updating the business applications to handle changes in the business processes as the businesses re-invented themselves to compete better.

    Nostalgia

    I do understand nostalgia when it comes to video games. I also understand there are many lines of Cobol lying around everywhere.

    Heck, I'm even working with an excel sheet packed with thousands of lines of VBA-COBOL, those days !

    But I really don't understand why one would develop a compiler for such an inferior language. Just emulate your AS400 FFS ! Like running Lemmings on an emulated Amiga !

      Lemmings on an Amiga has one advantage that I've not seen on other platforms - you can plug in two mice and play competitively again someone else. It can get very vicious... :-)

      Why lose performance emulating something instead of compiling to native code? The COBOL code carries out the business that pays the bills for the company. There's nothing inferior about that.

      You likely don't want your ATM be run on an emulator - much less the background processing that is done in batch for thousands of transactions. You want speed and reliability, no bad emulator.

      Inferior language? By what measure?

      Cobol is a big language, that's for sure. It codifies things most languages leave to libraries: file I/O, file structure, file availability, text encoding, sorting (files and in memory), and merging. For every failed operation, whether I/O or buffer exhaustion or arithmetic overflow, the language includes error-handling. Errors can be handled statement by statement, or globally, or by function, or sets of functions.

      I have found that most Cobol critiques, like most programming language critiques, are skin-deep. Lisp has too many parentheses; Python uses whitespace; Perl is write-only; APL is impenetrable. These are not useful measures of the utility of the language.

      It's also easy to mock Cobol for some of its antique conventions. But it's good at what it does. I defy you to rewrite any significant Cobol program in any other language of your choosing, in fewer lines or words.

    COBOL

    My first IT role was writing COBOL on a Vax VMS green screen thingy. That thing ran a whole chemical plant and COBOL was used for the finance bits. That was 25 years ago.

    COBOL has been long lasting on those critical processes.

    Learning Cobol is easy

    If you're old enough to be brought up on dry but fact filled manuals

    https://gnucobol.sourceforge.io/guides/GnuCOBOL%202.2%20NOV2017%20Programmers%20Guide%20(US%20Letter).pdf

    and you can have fun with some of the older free manuals on PDFs by setting up the machine simulators for the machines and DBs they ran on and accessed!

    ISO COBOL won't get you far

    Writing a COBOL front-end for GCC is a nice project. And there's some green-field COBOL development, and some number of existing COBOL applications which don't stray too far from the ISO standard; thus the success of GnuCOBOL and COBOL-IT.

    But the standard allows tremendous latitude, and implementations have dramatically different behavior. Nested PERFORMs behave differently on different platforms, for example, and the differences control where the program ends up at the end of a PERFORM, so that matters a bit. MF Visual COBOL currently has 17 dialects to pick from at compile time, more than 30 options for tweaking the dialect, and 50 or so other ways to modify what sort of COBOL the compiler actually implements. (And that doesn't include the OO or managed dialects, conditional compilation, or other runtime-behavior options.)

    And as others have pointed out, most real-world COBOL applications will depend heavily on the environment, whether that's one of the IBM mainframe ones such as CICS or something else. Yes, there are COBOL programs which just use POSIX / SUS or Windows APIs; but they're in the minority.

      Re: ISO COBOL won't get you far

      Michael, if you have an actual challenge for us, with money on the table, please get in touch.

      Our business model does not include trying to emulate every Cobol ever written. Rather, we know there are businesses that could save millions of dollars per *month* running Cobol applications on LInux. Most of them are unwilling to jump out of the frying pan and into the fire: from one proprietary vendor to another. It's also difficult to assemble on Linux the suite of services (RACF, IMS, JCL, etc.) that production Cobol applications rely on.

      Because Cobol environments are highly particularized, there is no such thing as "drop-in replacement". What a working Cobol compiler offers is the opportunity to move the application without re-writing it in, say, Java. Success will nevertheless require adjustments to the code and possibly, as you say, to the compiler. We know how to do that.
