Do not go gentle into that great night…
COBOL, the programming language extensively employed to operate Tier one/mission-important programs on mainframe computers – and popularly imagined of in some stylish youthful corners to be a relic of the dark ages – is truly in impolite great overall health.
That’s in accordance to a new survey by Micro Concentration now, which finds that soon after additional than sixty a long time in the creation ecosystem, COBOL code bases are – maybe startlingly to some – continuing to grow, as enterprises modernise programs.
In shorter, if COBOL were a man or woman it would now be keeping a Freedom Go – but earning additional use of it than numerous expected. (“Do not go gentle into that great night”)
COBOL Apps Normal 9.9 Million Lines…
The normal COBOL code foundation,now runs to 9.9 million strains, versus 8.4 million in 2017 – reflecting ongoing expenditure, re-use and enlargement in core organization systems by individuals functioning programs published in the language, Micro Concentration observed.
Describing it as a “dependable remedy that will go on to grow and thrive”, Chris Livesey, Micro Focus’s senior VP of software modernisation and connectivity reported: “Thanks to the authentic design’s readability, adaptability and portability, COBOL provides remarkable value for firms as a trustworthy remedy.”
(The survey more observed that 70 % of enterprises hope to modernise present programs as component of their strategic alter programmes, fairly than retiring them, when sixty three % reported that they will be improving upon present COBOL systems in 2020.)
So what do individuals modernising programs published in/all-around COBOL need to have to be specially knowledgeable of? Laptop or computer Company Overview questioned the experts…
Modernising Your COBOL Apps
Thilo Rockmann, Chairman and COO, Switzerland’s LzLabs, instructed us on a call: “The important thing is that the new ecosystem, where ever that sits, integrates neatly into the development chain of regardless of what you are going to develop…”
“If there are breaks from an company perspective involving what you are going to create in a person location and [how that brings together with] a diverse development chain, or development process, you will generally have friction.
“This is a person of the locations where enterprises generally have problems, as if you want to preserve COBOL programs functioning on a mainframe that stick to a diverse cycle to your Java, Python, development, that can bring about issues.”

He extra: “The approach wants to be as incremental as attainable.
“The language by itself is a lot less of an issue. A lengthy time back I had to preserve some COBOL code and it was not that hard, in spite of my mainly (formerly) applying C++ and Java.
“What is significant for developers is the ability to check the new code that you wrote all-around the mainframe, and check it in the ecosystem where your developers sit, and not need particular several hours [time slots] to do it on the mainframe.
“[Modifications are usually required to] operate your mainframe additional efficiently: if you operate it inefficiently you are going to pay back a large amount additional: substantial mainframe programs use a large amount of CPU time…”
Keith Banham, mainframe R&D supervisor at Macro 4, extra: “Modernising mainframe programs can require a variety of diverse solutions. Enterprises shouldn’t automatically go down the route of rewriting code or re-platforming devoid of producing an overall strategy that usually takes account a amount of diverse things.”
“Cost is definitely an significant thought.
“The assumption is that mainframe pricing is high relative to other platforms – so numerous organisations want to transfer as considerably as attainable off the mainframe to cut down MIPS intake. On the other hand, IBM has introduced new pricing solutions you ought to consider. Now, if you’re functioning new workloads, you can use the new Customized In good shape Pricing, which is less difficult, usually additional price effective and nearer to the Cloud/SaaS intake product. So, really do not think – do your sums and see if it is worth the transfer.”
Ultimately, of course, organization leaders need to have to weigh up the challenges of re-creating code versus the challenges of a long run absence of mainframe expertise weighing them up versus the challenges of organization interruption posed by a significant migration off mainframes.
Succession planning also has to be taken into account. Simply because there is a complete large amount of COBOL code out there and it evidently is not wafting off the cloud at any time quickly.
