The debate over COBOL’s continued relevance and indeed its future continues to persist in the developer community and IT world in general. But while every business has its language preferences, there is no denying that even though COBOL is 60 years old, it continues to play a vital role for enterprise business applications. COBOL still runs over 70% of the world’s business and more transactions are still processed daily by COBOL than there are Google searches made.
While many also debate the status of Java in relation to COBOL for business applications, COBOL remains the preferred choice for systems where application quality and operating cost remain important considerations, so often the case when addressing the ever-present issue of IT debt. When many businesses are facing mounting IT debt, the average cost per line of code for COBOL was projected to be £0.80 whereas the cost to address Java quality issues per line of code was £3.47, according to a recent IT study.
The benefits of COBOL, however, are not found in its exclusivity, but also in its ability to comfortably co-exist with other programming languages- such as Java – that are typically used to build new front-ends for new platforms and devices.
COBOL can function efficiently for vital business applications as a reliable language while also liaising with languages such as Java and C#, typically used in the construction of new interfaces; these languages combine forces in helping businesses deliver the services to support new requirements such as BYOD and other mobile initiatives through renewed, composite enterprise applications. While some in the industry may doubt COBOL’s relevance for today’s business applications – mainly due to its considerable age as a programming language – the fact that it has been vetted and proven over several decades actually stands in its favour: much of the required “new” functionality already exists, written in COBOL. It is merely a question of how it is made available to the user.
Add to this the flexibility of the language to be adapted for future needs, and its ability to liaise with other front-end technologies, and COBOL remains a lower-risk option for businesses because of its prevalence over the past half a century, and not in spite of it. It is a myth that IT organizations must choose between one language and another – they can in fact work with whichever language(s) make most sense according to their business requirements. And ageless COBOL continues to meet those needs.
Why does COBOL remain the smart choice for application providers and development teams?
Portability is the key.
‘Choice’ is a defining characteristic of the IT industry. Whatever the question – there are multiple answers. Whatever the challenge – there are multiple options. This is especially true for enterprise application platforms. Most enterprises sport disparate, heterogeneous platform environments.
Application vendors can have to support upwards of 40 platforms, with the appearance of new variants each year adding to the complexity.
IT organizations face internal pressures from tactical investment programs, a need to lower total cost of ownership (TCO), and a demand not to be locked into a single platform vendor. For most, the important measure is the TCO; both the initial investment charges and recurring annual hardware and software maintenance. The pressure is on to maximize ongoing value, while removing cost and platform complexity.
Increased commoditization puts portability center stage
Increases in processor power and hardware commoditization present IT buyers with choices when it comes to platform selection: Windows, Linux, Unix, PC or Mac, Desktops or VMs, Mainframe or non-Mainframe, iSeries, Data Center or Cloud. Exploiting this choice lowers TCO.
The blurring of demarcation between platform choices now means that software vendors must make their applications available on a wider range of platforms. Customers will, of course, choose an application based on its functionality, but the decision will also consider the breadth of platforms supported, relative ownership costs, user requirements, skills profiles, supply-chain policy, etc.
Market dynamics of key vertical industries throw even more challenges into the mix. Telecoms service providers, for example, need to lower their cost base and leverage more ROI from their existing IT investment, as well as preserve the differentiation their systems give them. Delivering this cost-effectively, regardless of platform selection, is a major driving force. In financial services, competitive advantage is also deeply entrenched in application code, so it’s important to be able to re-use and harness this value.
Business dynamics of end-user requirements also have a direct impact on the application supplier as the application must work consistently and deliver a uniform process and user interface across the platforms their customers deploy on. This has a knock-on effect in terms of increased support and development costs, and slower development cycles as they get to grips with different tools to build systems on different platforms.
The priority for application providers and corporate development teams is to focus efforts on developing and enhancing their own products, rather than ensuring that they work on an idiosyncratic platform choice. Using different development paradigms to support different deployment options only deflects that focus.
Knowing that the end-user just wants correct business functionality deployed to his chosen list of deployment environments, the application provider or development team needs to ask:
Can we provide business functionality needed on our new platform(s) of choice?
How can we streamline the process of building this functionality to improve time-to-release, reduce our internal costs, and remain flexible for the next set of user requirements?
The ideal solution would be to tackle both issues using a single, efficient method of building functionality, ideally re-using functionality that already exists, and replicating this unchanged across the list of deployment platforms.
Micro Focus’ commitment to COBOL portability leads the way
To deploy business functionality across multiple platforms, Micro Focus tools are designed to help enterprise application providers build systems that are truly portable. Applications created for one platform can be re-used on a new platform essentially without change. These “applications” are the same tried-and-trusted applications that having been running for decades in COBOL.
Thirty years of industry leadership and investment in technology enables Micro Focus to shape both the COBOL language standard and COBOL’s implementation in a variety of products across a vast array of platforms. The Micro Focus approach maintains the portability of the COBOL language, irrespective of product or platform attributes.
The mainframe environment is subtly different. While the COBOL is very similar, the interdependency on transaction systems, mainframe databases, job control systems and other mainframe systems, make the portability of such systems a more substantial task. The mainframe offloading and rehosting tooling offered by Micro Focus has helped both ISVs and enterprises successfully modernize mainframe applications to a distributed world. Over 600 successful rehosting projects have been achieved through this approach.
Application development tools enhance portability
In terms of the development method and process, Micro Focus provides consistent and class-leading application development technology that enables today’s developer to analyze, develop, debug, test and deploy their applications across an array of platforms. The integrated development environments from Micro Focus allows for instantaneous edit/debug cycles, feature-rich developer tooling, running under new industry-leading frameworks such as .NET and Eclipse. Onward development from Micro Focus puts COBOL in the cloud and on Android.
This focus on developing and enhancing COBOL for both distributed and mainframe environments enables Micro Focus to offer an unrivalled level of portability in the enterprise application marketplace. It is one of the main reasons why COBOL continues to be the smart choice for application providers and development teams across the industry.
Next time you do a platform review and your application provider cannot support your new choice – ask them why they are not using portable technology that puts you at the centre of their strategy.
COBOL: It’s easy to learn and easy to use.
Think about the last gadget you bought, and then think about how you got it to work. Did you put the device to one side while you spent some quality time reading the manual from cover to cover? Or did you rip it out of its packaging and try to start using it straight away?
It’s only natural to want work out how something works ourselves and, let’s face it, most gadgets are fairly easy to figure out.
There’s also the fact that maybe we don’t want to read the manual. Possibly over time we have learnt not to trust manuals, we shy away from technical information and prefer to avoid anything to do with techno-babble.
It’s the same story in the day job. We avoid having to “figure out” technical facts and figures, especially if we just have to stare at it, un-coached. We are drawn to things that make sense without too much effort, that are easy to understand visually and, if they are languages, that are easy to write.
The COBOL computer programming language stated its objective to be ‘easily understood’ a very long time ago. Its authors prescribed its value as part of its name: Business-Oriented. The ideal was that the business community could use this technology to make life easier. Targeting a previously ignored audience was the cornerstone of its success.
COBOL is structured in terms of its layout, and uses active English-derived constructs (ADD is ADD, EQUALS is EQUALS, PERFORM is ‘go and do’ etc.). These tell the reader at a glance what the code is trying to achieve. New Micro Focus employees are shown some COBOL code as part of their induction training and are asked to describe the code sample with two minutes coaching. Everyone succeeds because the language is a naturally intuitive construction that anyone can write.
As anyone can write it, it becomes possible to create low-cost high-availability resource pools to construct applications – with its logical structure leading to a fairly consistent implementation.
Consider defining some data: with COBOL the rules are pretty self-evident and quite explicit. For example, 01 item-a pic 99V999 is a data item ‘item-a’ defined as (a picture) a two-digit number with three decimal places. It is exact, straightforward and easy to pick up.
As anyone can read it the downstream benefits are equally significant. First, it means the resource pool available to work on COBOL systems is conceptually unlimited. There is no barrier to entry for future COBOL programming skills. This means a lot in terms of strategic planning and investment, and in terms of dollars.
Second, if anyone can read it anyone can maintain it. A second generation of programmers can code COBOL and also code in existing COBOL applications they hadn’t originally written. Also non-developers can at least follow the flow where it was necessary: QA staff can assist with code walkthroughs and debugging work, systems administrators can provide appropriate support functions and be more familiar with the applications themselves.
Third, the high legibility of COBOL avoids a major and common pitfall – namely that coders will simply rewrite something they do not understand in their preferred language. COBOL typically passes the comprehension test. As Michael Coughlan of the University of Limerick says, “It’s not a write-only language. You can come back years later and understand the code.”
COBOL became the dominant business language for very good reasons. It evolved as COBOL programmers picked up and added to existing applications, enabled by the fact that the language is easy to understand. “COBOL is one of the few languages written in the last 50 years that’s readable and understandable”, says Mike Gilpin, Analyst at Forrester
More recent language enhancements and modern OO syntax enables managed-code developers to cross boundaries quickly and support COBOL development as the constructs of Object Oriented COBOL will be familiar. Conversely, COBOL programmers need only acquire modest new syntax to consider providing COBOL business functionality as consumable objects.
Whatever the business requirement, COBOL remains one of the lowest-risk and lowest-cost options in terms of application provision, simply because it is easy to gain the skills to develop it.
COBOL is Adaptable
The hi-tech world of IT embraces and celebrates ‘new’ more than any other industry. New, creative innovations enjoy a meteoric rise in popularity and interest – seemingly overnight – for the potential benefits they can deliver to early adopters. What do Smart phones, Tablet computers, iPods, social media, and wireless networking have in common? They were all innovations of the last decade, and already we can’t imagine life without some of them.
In a market crowded with new entrants each year, existing and established technologies have to fight to remain current, relevant and valuable.
So how has COBOL, a sixty-year-old language, managed to remain a forerunner in the world of enterprise application development?
The answer lies in its adaptability. It evolved, and continues to evolve, according to the needs of the day by welcoming new phrases, new meanings, even letters, and by slowly retiring anything no longer used.
Consider the growing use of SOA and Web Services, and the range of technology elements – such as XML, WSDL, SOAP and others – the framework needs for things to talk together. Micro Focus was quick to market with tooling to allow the rapid creation of Web Service or SOA versions of existing COBOL applications.
These technologies have been introduced over the last thirty years or so:
And these platforms and environments have come into being during the same period:
These platforms and technologies share a common thread – the investment that Micro Focus has made to ensure these new environments are accessible from the COBOL world in a meaningful, practical sense. In most cases, Micro Focus was first to market with product technology that supported the new ‘standard’ and enabled deployment to new environments.
COBOL continues to evolve to take advantage of emerging technology: In 1974, 1985 and 2002 the COBOL language standard was updated. Micro Focus played its part both by participating in the standards body, and also being one of the pioneers of the new standard from a compliance perspective. This is illustrated by the ‘industry firsts’ to come from the Micro Focus stable.
- 1975 – COBOL compiler for microcomputers
- 1980 – Visual Debugger 1982-COBOL for UNIX variants
- 1984 – 32bit support 1985 – CICS emulation on the PC
- 1990 – Assembler emulation on the PC
- 1991 – COBOL compiler and development tools under Windows
- 1995 – Object-Oriented COBOL 1996 – Native Windows IDE
- 1997 – Internet COBOL application support
- 1998 – IBM mainframe development system under Windows
- 1999 – 64bit support 2001 – COBOL and Java mixed language support
- 2003 – COBOL Web Services support
- 2004 – Deployment CICS and transaction engine on UNIX/Linux
- 2005 – Deployment JCL engine on Windows/UNIX/Linux
- 2006 – Deployment IMS/TM engine on Windows/UNIX/Linux
- 2007 – Deployment IMS/DB engine on Windows/UNIX/Linux
- 2008 – COBOL language environment for Microsoft Visual Studio
- 2009 – Rapid mainframe DB2 to Microsoft SQLServer migration capability
- 2010 – Visual COBOL-deployment of applications into .NET, JVM and Azure
- 2011 – Windows-based dedicated mainframe application testing platform
We now see COBOL applications written decades ago being deployed to cloud, .NET and JVM. Micro Focus’ commitment to its customers is most emphatically provided through its backwards compatibility policy: That any COBOL, anywhere, that conforms to the standard(s) will compile with the latest product. This guaranteed forward path serves to keep applications current and provides a low-risk environment for systems development. This contrasts starkly to other technology options where the code was good for a couple of years but had to be rewritten because a compiler release had changed.
The outcome is that COBOL can be easily used as part of a leading-edge technology strategy, and part of contemporary deployment architecture, using SOA, websites, Application Servers etc. One healthcare provider took its applications, built using COBOL development technology licensed in 1984, and re-used the business logic more or less unchanged as part of a program to provide web-based access to those business applications via SOA. The underlying COBOL code remained unchanged as the work invested in COBOL by Micro Focus over the years ensured that the leap to SOA could be achieved without changing the core code.
The future brings undefined generations of technology innovation into view, renewing the requirement for investment, innovation and certification by Micro Focus on behalf of its customers. From the advances in deployment options, including cloud and mobile devices, to supporting mainframe CICS application running natively in Azure, as well as moving to Windows 8, Micro Focus will continue to invest proactively to ensure customers’ future strategic decisions allow their existing investments to remain secure and protected.
COBOL Adoption & Survey Results
Roger’s adoption curve is a well known model which shows how new ideas and products get adopted over a given time-frame. Basically, things start relatively slowly, there’s an accelerated mid-phase where a majority of the audience ‘buy in’, and then there’s a decline to a small remainder.
Once over a certain point, a growing trend takes on a life of its own and becomes self-fulfilling. Commentators from Geoffrey Moore[ to Malcolm Gladwell have attempted to describe how to get up (and over) the steep initial slope of the adoption curve – the Chasm. Once you’re over this, though, and on an upwards trajectory the benefits are impressive. Buying decisions, particularly in risk-averse corporations, will go your way as businesses opt for tried-and-trusted solutions to their business pains. A winning formula will be re-used as often as possible, especially if the cost of bringing it on board in terms of skills and technology is relatively low.
Right from the outset in 1959 COBOL immediately presents an attractive proposition as a relatively low-cost, innovative IT power… before it was called IT, of course. The language’s ability to charm the business community lay behind its take up – after all, it wasn’t called the Common Business Object Language for nothing. Within a decade, long before the appearance of other languages we know today, COBOL was the ‘go to’ language of data processing for the business world.
Micro Focus and Vanson Bourne have surveyed the industry and drew some pretty illuminating statistics[ about the ubiquity of COBOL in the workplace. The global survey asked COBOL-connected architects, software engineers, developers, development managers and IT executives from 49 countries to determine and calculate the volume of COBOL application code running production systems, as well as the strategic importance of COBOL applications to their business, future application roadmaps, planning, and resources.
“For this year’s survey, Vanson Bourne set out to gather data from the IT community on COBOL’s continued relevance, in addition to getting a better picture of just how much COBOL is currently out there in use,” said Jimmy Mortimer, Senior Research Consultant at Vanson Bourne. “Whether this increase in code is externally driven or motivated by new technology or business transformation initiatives, it is clear that the importance and volume of COBOL in use continues to grow each year.”
Other data regarding overall volumes of COBOL code suggests that:
- COBOL Market Shown to be Three Times Larger than Previously Estimated
- Global COBOL Code Volume hits new highs: More than 800 Billion lines of code running on production systems and in daily use, far exceeding any previous estimatesNearly half of the survey’s respondents expect the amount of COBOL in use at their organization to increase in the next 12 months.64 percent of respondents intend to modernize their COBOL applications and 72 percent of respondents see modernization as an overall business strategy.
- When asked about their company’s plans for COBOL and the cloud in 2021, 43 percent of the survey’s respondents stated that their COBOL applications do and will support cloud by the end of the year.

This indicates COBOL’s place in IT and in the business world as a whole. This volume of code and level of investment – especially given the importance of some of the business functions it provides – creates a lasting heritage.
How much COBOL is really out there?
Was the proliferation of COBOL over the decades inevitable? Was it because there was nothing else around? No. By being smart about its market position and its target audience, COBOL gave itself the very best chance for survival.
Over the years COBOL’s highly reusable nature has seen it pervade across the enterprise. After all, why write applications from scratch if the business function already exists? Why risk application failure and undergo the cost of investing in similar capabilities, when an existing one can be re-used and refined to do a new task? The answer is most people didn’t take the risk, and chose to exploit the COBOL systems they had.
Also, how did organizations whose reliance on COBOL deepened through a ‘re-use’ policy meet the growing skills challenge? In fact, it was simply down to COBOL’s ease of learning and highly readable format. These enabled resource pools to be flexed and scaled out easily. What’s more, its popularity – then without question – ensured there was a ready supply of programmers willing to take a role.
Today that skills pool may look markedly different – the programmers who cut their teeth on COBOL have aged, and subsequent generations of programmers have been brought up on different languages that reflect the changing IT landscape. Now, there is more code than ever before, more opportunities for re-use and continually evolving requirements to deliver existing business functionality into new channels and across new devices.
In short, the COBOL heritage is as valuable today as it ever was.
The demand for skilled COBOL programmers remains strong. According to Simply Hired, COBOL jobs listings have increased over 100 percent since November 2009. Over 100 universities have recognised the opportunities this presents and have signed up to the Micro Focus COBOL Academic program which provides free access to the latest technology and teaching tools for enterprise application development. Around 9,000 students graduate every year with vital COBOL skills.

The continued investment in COBOL over the years means that today’s IT teams can create exciting user interfaces using latest technologies such as WPF, JavaFx, HTML 5 or Silverlight to wrap around proven business logic implemented in COBOL. XML integration means that COBOL applications can be deployed as web services in the cloud as servicing applications, developed to run on iOS and Android platforms. COBOL’s place in the next generation is already proven.
According to research by the Standish Group, organizations consider re-using or “modernizing” existing COBOL-based systems to be a better option than re-writing or replacing the application with an off the shelf packaged solution – risking the valuable IP that was written into the COBOL over the years. For cost, risk, competitive advantage and time-to-market reasons, the value of the COBOL heritage seems set to last into the future.
COBOLs Robustness and validity
Who would go mountaineering in stiletto heels, or drive off-road in a Ferrari? Let’s face it, there are some tools that are just plain wrong for the task in hand. This is especially true in IT. Business applications need to be built in something that is robust and reliable. Who wants to face a user revolt when systems keep crashing or the wrath of the CFO when numbers don’t add up?
At the high end of enterprise computing there are key criteria that describe the technological requirements of the business systems.
The criteria can be summed up as: Robustness and validity, strong data manipulation, accuracy, speed and accessibility.
As you would expect from a Micro Focus blog, our assertion is that COBOL is the only language that meets all these criteria. It makes sense for us to take each one and show you how COBOL fits it.
The language used to create and support applications needs to be as low-risk and error-free as possible to support the business.
COBOL’s type-rich language allows data to be described accurately with explicit scope and limits. This richness means you can meet your corporate coding standards, ensuring consistency and accuracy across your organization and third parties, including partners and industry specific compliance requirements such as Basel II and (Insurance one). This applies to data management in the same way.
For example – a MOVE of number-a of PIC 999 to alpha-a of PIC AAA will invoke a warning.
The need to write robust code is addressed by type checking when you come to compile. This improves the effectiveness of the application creators, helping them avoid any unnecessary pitfalls and deliver more robust applications.
As you run the code, you can set switches to validate the running of the code, heading off any serious errors that may have crept in.
As the language lends itself to error-free coding there’s no need for you to write huge error checking routines.
Types are applicable to the business user, they reflect the concepts of the data the user needs, in the right format. So, numeric-edited types for even stronger formatting and type management, such as blank when zero, decimal point etc. This is taken care of by typing rules in the language so you don’t have to spend time formatting what gets displayed on the screen.
Here are a couple of examples:
|Input Value||Output Value|
With these output items defined as:
77 numeric-edited-date-field PIC 9999/99/99
77 numeric-edited-bwz-negative-field PIC –ZZZ,ZZZ.99
COBOL’s Numeric arithmetic accuracy
Essential for robust business applications, COBOL delivers arithmetic accuracy to 38 digits – that’s more than any other language.
An 18 integer number is defined simply as number-1 PIC 9(18).
Micro Focus supports 38 significant digits (i.e. both sides of the decimal point) in a numeric field.
You’ll get an idea of how COBOL trounces Java when it comes to the accuracy needed in financial applications in this blog.
COBOL’s Strong data manipulation
COBOL comes equipped with a range of capabilities to deliver stronger data manipulation, these include:
- Faster data access than any RDBMS
- Data files of a variety of formats �
- File size limits set by the operating system. In fact, the Micro Focus file handler has no limit on what it can read (the OS limit is a sizeable 2 ^ 64)
- Data manipulation and reporting built in to the language with the SORT capability. This uniquely enables you to SORT and filter within COBOL without having to engage another tool or any extra steps.
- Any element of any definition in any record can be used as the SORT ‘key’
- Multiple file merging and record-level manipulation (even re-arranging the order)
- Multiple output data sets to automate complex data processing with simple language controls
- Massively faster than the alternatives
Speed is a key criteria for any business applications, they need horsepower to deliver both computational speed and batch support. COBOL is FAST!
Portable across a wide variety of platforms, COBOL offers deployment flexibility and can also be optimized for specific hardware, increasing performance and throughput. COBOL’s “code generator” exploits target platform technology to deliver optimal performance, at the same time the technology also enables the creation of fully portable executable code.
While the coding language has to deliver against all of these criteria, it has to be accessible and meet the demands of business. Programming languages don’t exist in isolation. They only deliver value in the hands of the coders, who in turn are only as good as their ability to align the application to a business need. To make a valuable business contribution, the language should also combine a state of the art environment for building robust apps, including latest features (Intellisense, rapid code/debug, UI builder) and be built on the latest frameworks (Visual Studio and Eclipse).
Figure 1- state of the art COBOL IDE based on industry-standard Eclipse and Visual Studio frameworks
Figure 2 – undefined items are automatically highlighted (red underline)
Figure 3 – Right-click to see options of likely statement or variable names (“Intellisense”)
Not only does this make the language more relevant to the business context, it makes it easier to learn and maintain.
In short, COBOL is the language of business because it is designed with business in mind. Business relies upon and trusts technology that most closely reflects and supports how it sees the world. COBOL has been consistently developing and evolving to meet the changing demands of business for the last fifty years. Investment in the technology by Micro Focus over the last thirty-six years has ensured that COBOL continues to deliver against the criteria that business applications require, and will continue to do so for decades to come.
The Future of COBOL is NOW
As IT spend declines, innovation is expected to soar and IT departments have to exploit leading edge technologies for application deployment to stay ahead of the game. With new technologies comes a need for new skills without losing those that already support existing critical systems.
The future of COBOL lies in Micro Focus Visual COBOL, an integrated development and deployment tool that helps you deliver more from your existing core systems investment.
We have identified the five core attributes the IT infrastructure has to exhibit to support current and new challenges as cost-efficiently as possible.
1. COBOL’s Foresight
Ensuring your enterprise applications meet tomorrow’s needs today
Whatever your chosen programming language, it has to keep up with the changing IT landscape. COBOL can underpin contemporary deployment architectures, leading edge technology and composite applications within Java, C++ & C#.
COBOL applications written more than a decade ago are now being deployed to cloud, .NET and JVM. Visual COBOL enables you to exploit new market opportunities and extend your existing investments by deploying current applications onto new platforms, including .NET, JVM and the cloud as well as Windows, UNIX and Linux platforms.
2. COBOL’s Heritage
Five decades of heritage, thousands of organizations, billions of lines of value,
New application development rarely starts from a blank sheet of paper. Innovations often arise from delivering business applications through new channels. Using the extensive business logic built into existing COBOL applications in new environments for decades to come will maximize both investment and market opportunity.
- Its highly reusable nature is why COBOL permeates the enterprise. Why write new if the business function already exists?
- Because it is easy to learn and highly readable, COBOL enables resource pools to flex and scale up easily
- Alternative development languages can rapidly access COBOL value using native semantics and data types
3. COBOL’s Portability
The original write once, run anywhere technology
End-users only want one thing: Functionality on the platform of their choice. It’s up to development teams to ensure that they deliver functionality that’s streamlined to work on the right environments.
Our COBOL technology is designed so that the same application will run unchanged across a variety of platforms and operating systems, without the programmer having to worry about the specifics of the environment. Because it’s platform independent, the Visual COBOL deployment technology means developers can focus on building application value rather than on the nuances of the operating system. Visual COBOL provides true portability for applications to ensure that their value endures long into the future.
4. COBOL’s Fitness-for-purpose
Engineered for building great business applications
Today’s front-end applications need development tools that sit in a browser or other thin-client interface, the back-end needs strong and reliable IT infrastructures that offer robustness and validity, strong data manipulation, accuracy, speed and accessibility. In short, something fit for your business needs.
Visual COBOL takes advantage of COBOL strengths as a business critical programming language – numerical arithmetic accuracy to 38 digits and strong data manipulation and SORT capability – and provides an intuitive, unified environment for building robust applications.
5. COBOL’s Readability
Ease of learning, reading and writing enables you to focus on business
Change is inevitable, so why make updating and maintaining applications harder than it needs to be? As a language COBOL is simple to understand and doesn’t necessarily require prior language-specific experience. This contrasts with many programming languages where, even with the skills to write it, the code is hard to understand.
As Visual COBOL integrates with industry standard IDEs such as Eclipse and .NET, it puts COBOL at the finger tips of all your programmers, putting COBOL in the environment your developers are familiar with and using tools they already work with.
