Released at [[APL83]], Dyalog sold very few copies due to the lack of interest in either Unix or the nested array model. Subsequent sales were also limited, with only a single licence sold through Zilog partly due to the Z8000's limited popularity. Supported by Dyadic's APL consulting and later by sales of Unix hardware, Scholes and Streeter continued work on Dyalog by porting it to a wide variety of Unix systems in response to requests from users; in 1995, Scholes was awarded the [[Iverson Award]] jointly with [[Peter Donnelly]] for his work on the Dyalog interpreter. Although it continued to run significant losses every year, Dyalog slowly acquired users during the 1980s, including current client [[wikipedia:SimCorp|SimCorp]]. In 1991, Dyadic hired [[John Daintree]] to begin work on the <source lang=apl inline>⎕WC</source> graphical user interface for [[wikipedia:Microsoft Windows|Microsoft Windows]]; Dyalog for Windows debuted at [[APL92]] and quickly become Dyalog's main platform.<ref name="taylor"/> | Released at [[APL83]], Dyalog sold very few copies due to the lack of interest in either Unix or the nested array model.

In 1996, John Scholes introduced a new form of functional definition to Dyalog based on his studies of the functional programming language [[wikipedia:Scheme (programming language)|Scheme]], which he called [[dfn]]s, for "direct functions". Another major addition to the language began in 2000, when John Daintree was invited to participate in the design of Microsoft's [[.NET]]. Based on this work, and the [[namespace]]s which he had added to the language in 1994 to deliver a Windows GUI API and an interface to COM/OLE, Daintree developed an [[Object-oriented programming|object]] model for Dyalog, based on concepts from [[wikipedia:C_Sharp_(programming_language)|C#]] and [[wikipedia:Visual Basic]]. | In 1996, John Scholes introduced a new form of functional definition to Dyalog based on his studies of the functional programming language [[wikipedia:Scheme (programming language)|Scheme]], which he called [[dfn]]s, for "direct functions".

In 2005, Dyadic transferred management to CEO [[Gitte Christensen]] and CTO [[Morten Kromberg]], and sold ownership of the company to a group of investors including their company Insight Systems. With this arrangement, the development team at Dyalog grew rapidly. Dfns were promoted as "mainstream" APL features, with the result that many newer APLs only support dfns, abandoning traditional [[defined function]]s completely. Daintree's work on objects resulted in the addition of full object oriented programming capabilities to Dyalog APL in 2006. The influence of the Microsoft's .NET Framework also led to a project to create a new language called [[APL#]], prototypes of which were released in 2010. The project was abandoned in 2012 when Microsoft deprecated [[wikipedia:Microsoft Silverlight|Silverlight]]. | In 2005, Dyadic transferred management to CEO [[Gitte Christensen]] and CTO [[Morten Kromberg]], and sold ownership of the company to a group of investors including their company Insight Systems.
