Do not go mild into that very good night…
COBOL, the programming language greatly utilized to run Tier one/mission-crucial programs on mainframe desktops – and popularly thought of in some stylish younger corners to be a relic of the dim ages – is in fact in impolite very good wellness.
That’s in accordance to a new study by Micro Aim right now, which finds that after more than sixty a long time in the output surroundings, COBOL code bases are – possibly startlingly to some – continuing to expand, as corporations modernise programs.
In brief, if COBOL ended up a human being it would now be holding a Flexibility Pass – but producing more use of it than lots of expected. (“Do not go mild into that very good night”)
COBOL Applications Typical nine.nine Million Lines…
The average COBOL code foundation,now runs to nine.nine million lines, versus eight.4 million in 2017 – reflecting ongoing investment decision, re-use and growth in main business enterprise techniques by all those jogging programs penned in the language, Micro Aim identified.
Describing it as a “dependable remedy that will proceed to expand and thrive”, Chris Livesey, Micro Focus’s senior VP of software modernisation and connectivity reported: “Thanks to the primary design’s readability, adaptability and portability, COBOL adds incredible worth for corporations as a trusted remedy.”
(The study even further identified that 70 p.c of enterprises count on to modernise current programs as element of their strategic modify programmes, fairly than retiring them, when 63 p.c reported that they will be strengthening current COBOL techniques in 2020.)
So what do all those modernising programs penned in/about COBOL have to have to be notably knowledgeable of? Computer Company Evaluate asked the experts…
Modernising Your COBOL Applications
Thilo Rockmann, Chairman and COO, Switzerland’s LzLabs, told us on a call: “The crucial matter is that the new surroundings, where ever that sits, integrates neatly into the growth chain of regardless of what you are going to develop…”
“If there are breaks from an company viewpoint involving what you are going to create in just one spot and [how that brings together with] a distinctive growth chain, or growth system, you will always have friction.
“This is just one of the parts where corporations usually have problems, as if you want to keep COBOL programs jogging on a mainframe that follow a distinctive cycle to your Java, Python, growth, that can result in challenges.”

He added: “The solution desires to be as incremental as feasible.
“The language by itself is significantly less of an problem. A lengthy time ago I had to keep some COBOL code and it wasn’t that really hard, even with my mainly (previously) making use of C++ and Java.
“What is significant for builders is the skill to check the new code that you wrote about the mainframe, and check it in the surroundings where your builders sit, and not demand specified hrs [time slots] to do it on the mainframe.
“[Changes are usually essential to] run your mainframe more effectively: if you run it inefficiently you are going to pay back a good deal more: massive mainframe programs use a good deal of CPU time…”
Keith Banham, mainframe R&D manager at Macro 4, added: “Modernising mainframe programs can include a array of distinctive possibilities. Enterprises shouldn’t routinely go down the route of rewriting code or re-platforming without having building an total system that takes account a variety of distinctive elements.”
“Cost is obviously an significant consideration.
“The assumption is that mainframe pricing is superior relative to other platforms – so lots of organisations want to shift as a lot as feasible off the mainframe to decrease MIPS intake. However, IBM has released new pricing possibilities you ought to look at. Now, if you’re jogging new workloads, you can use the new Customized In good shape Pricing, which is simpler, generally more price tag successful and nearer to the Cloud/SaaS intake design. So, do not presume – do your sums and see if it is truly worth the shift.”
Ultimately, of study course, business enterprise leaders have to have to weigh up the challenges of re-composing code versus the challenges of a potential absence of mainframe techniques weighing them up towards the challenges of business enterprise interruption posed by a big migration off mainframes.
Succession arranging also has to be taken into account. Due to the fact there is a whole good deal of COBOL code out there and it plainly isn’t wafting off the cloud anytime before long.
