Phrogram was a commercial programming language designed for beginning and intermediate programmers of all ages. Its predecessor, Kids Programming Language (KPL) was first released in August 2005 and its distribution was discontinued in May 2008.〔(Phrogram's KPL page )〕 Phrogram was first released in October 2006 as v2.0; its current version, v2.5, was released in September 2008. As of July 15, 2015, Phrogsoft announced on their official website to cease the sale and distribution of its software. == Technical overview == Phrogram comprises a programming language and integrated development environment, or IDE, bearing some similarities to Visual Basic. The language supports a number of scalar and complex data types, including structures, and provides limited support of objects (excluding inheritance and polymorphism). It features two "modes" - one for two-dimensional graphics and one for three-dimensional; these modes cannot be used at the same time. Phrogram targets the Microsoft .NET Framework and provides many runtime functions and methods for interacting with that platform. Because of this, Phrogram operates only on the Microsoft Windows series of operating systems that support the .NET Framework. A Phrogram program consists of a collection of nested code blocks. On the highest level is a ''Program'' block, and within this ''Method'' blocks and ''Function'' blocks are defined. Functions and Methods are both chunks of reusable code, available in the Program scope; Functions return values, while Methods may not. Data structures are defined within the Program scope. Variables must be declared and typed at the time of declaration. the latest version of Phrogram, v2.5 (released September 2008), runs on Windows Vista and Windows 7 (both 32 and 64 bit editions of each), as well as on Windows XP and Windows 2000. Phrogram Express, the lower-priced version, does not include the Class Library Browser or the ability to export code to a free-standing executable package (capable of running outside the Phrogram IDE). Phrogram Academic, the full-featured version available for educators and students, has started to attract some interest as a way of teaching programming but is not usable to teach programming on operating systems other than Windows or to teach the concept of portable programming. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phrogram」の詳細全文を読む スポンサード リンク
