The Carlisle Group

“When converting CAS from DOS to Microsoft Windows in 1995, we experimented with the available APL implementations and settled on Dyalog. Dyalog was out in front with many enhancements to the core language and the APL environment. Over the years they have continued to outpace the competition, and have proven a superb choice as a long term partner in creating value for our customers. Some of the many reasons we continue to heavily invest in development using Dyalog are:

• GUI Options
  From built-in GUI objects to WinForms to WPF, Dyalog has provided a rich environment that allows us to mix and match techniques and to gradually move from one GUI framework to another. Despite the availability of newer technologies like WPF, and the ease with which they can be accessed through Dyalog, the built-in GUI objects of Dyalog are still extremely useful, and will be for many years to come.
• Namespaces, Reference Arrays, and ‘dot’ syntax
  Dyalog Ltd’s well-crafted and natural extensions to APL are a key component of our ability to compete successfully against much larger firms in the corporate software market. These features are invaluable for code management and GUI programming, and are indispensable for driving COM objects and servers that we take extensive advantage of, like .NET, Microsoft Excel, Microsoft Word, and the Microsoft Windows Scripting Host.
  
• Object Orientation
  Building on their pioneering work in namespace technology, Dyalog Ltd has implemented full object-oriented extensions into APL. In addition to giving us new ways to write and organise our code, this has proved to be a critical feature in delivering a scriptable, domain-specific language in our products.”
