Many Businesses Still Love COBOL (techradar.com) 195

Posted by EditorDavid from the 60-year-old-languages dept.
TechRadar shares some surprising results from a new survey of enterprises using COBOL and mainframe technologies: According to a survey by Micro Focus, which follows data gathered in previous 2017 survey, 70 percent favor modernization as an approach for implementing strategic change. This is opposed to replacing or retiring their key COBOL applications as they continue to provide a low-risk and effective means of transforming IT to support digital business initiatives...

This is further supported by the results of the survey with an increase in the size of the average application code base which grew from 8.4m in 2017 to 9.9m this year, showing continued investment, re-use and expansion in core business systems.
"92 percent of respondents felt as though their organization's COBOL applications are strategic in comparison to 84 percent of respondents in 2017," according to the official survey results. The survey spanned 40 different countries, and involved COBOL-connected architects, developers, development managers and IT executives.

"COBOL's credentials as a strong digital technology appear to be set for another decade," according to Micro Focus' senior vice president of application modernization and connectivity. "With 60 years of experience supporting mission-critical applications and business systems, COBOL continues to evolve as a flexible and resilient computer language that will remain relevant and important for businesses around the world."

      Something I always find a bit unnerving about the post Y2K programming culture is the short time horizon. Modern languages constantly breaking compatibility in order to 'stay relevant', developers thinking in terms of months or maybe a few years rather than decades.

      On my current project, we have had to update our version of Python a total of 5 times. We have probably lost about 6 months of dev time to that over the years, and keep having to rewrite things to work around the language changes. If our stuff was doing anything mission critical, I would have pushed for just staying on 2.3....

    Line for line COBOL is a very inefficient language to write in

    In the early 80's I worked for an electronics manufacturing company whos data processing department was using mainframes running COBOL. For years our production staff had been asking for a fairly simple application, one that would give us a fully nested bill of materials needed to build any particular product so that we could get an early start on the procurement process. They said it was not possible.

    One day I sat down at my IBM PC XT which I had adapted a terminal interface card to connect to the mainframe so that I could read a virtual representation of the terminal console for the mainframe. In less than 6 hours I coded up a Pascal application that could extract all the individual bill of materials and calculate how many of each assembly would be required, and then did a fully exploded list of every nut, bolt, diode, filter, and resistor that would be required to ship a particular order. It took about an hour to run and handed me what would normally take two weeks of manual processing. A production analyst could simply fill in the model number and a quantity, and my little program could then tell you in less than an hour what long-lead items were likely to hold up the production line. With management's signature, we could then get those long lead items on order that very same day and potentially save as much as a month on the delivery time of an order.

    After seeing my printed report my manager grabbed my report from my hands and marched straight down to the data processing managers' corner office to confront them about why they couldn't do the same thing. They finally relented and assigned their most experienced COBOL programmer to code up the exact same report. I had to run my program again because the DP management kept my only copy.

    My little Pascal program took me about 6 hours to write, and their same COBOL project took over 6 man-months to write and test. They even had direct access to the data on the mainframe while I had to dance through fiery hoops to extract that same information and build my own temporary database.

    The DP manager offered me a job writing COBOL, and needless to say, I refused the offer. About six months later I left the company to become a professional programmer and never looked back. I stopped counting at 24 different computer languages more than 30 years ago when I realized it is not in your best interest for management to find out you know how to write in particular languages, like COBOL or PL1, because one day they will very likely ask you to "fix" something that would be better rewritten in another language better suited for the assignment. Some languages should just be retired, and its safe to say COBOL is one of them.

      This can be misleading because it is anecdotal and based on what COBOL was like on mainframes. These days, with a modern compiler, using free form COBOL (no line numbers or strict formatting), COBOL is comparable to other languages. So it does not apply or accurately describe these more modern implementations such as GNU COBOL which support free form COBOL and are easier to use.

      That's probably because your little program stumbled over all the corner cases that the COBOL programmers spent years working into their code.
