Early history

VisualAge was born in the IBM development lab in Cary, North Carolina. Cary (ˈkeər'i is a town in Wake and Chatham counties in the U The Cary lab was established in 1984 and staffed at the time primarily with IBM employees transferred from Poughkeepsie, New York. Year 1984 ( MCMLXXXIV) was a Leap year starting on Sunday (link displays the 1984 Gregorian calendar) Poughkeepsie (pəˈkɪpsiː is a City in New York, USA and serves as the County seat of Dutchess County, located in the Hudson The Lab had responsibility for application development tools. The EZ View dialog manager product, a personal computer derivative of the user interface elements of the ISPF 327x product was one of the products. The lab also had a group which was one of the early adopters of object-oriented programming technologies within IBM using an internally developed language called ClassC to develop applications with more sophisticated graphical user interfaces which were just starting to be widely available. Object-oriented programming (OOP is a Programming paradigm that uses " objects " and their interactions to design applications and computer programs

Eventually, with the availability of usable implementations of Smalltalk in for IBM PC-AT class machines allowed IBM advanced technology projects experiment with Smalltalk. Smalltalk is an object-oriented, dynamically typed, reflective programming language. At about the same time, visual interface construction tools were coming up on the radar screens. Smalltalk research projects such as InterCons by David N. Smith of IBM, and Fabrik by a team at Apple led by Dan Ingalls were building interactive graphical applications built from composition of graphical primitives. International Business Machines Corporation abbreviated IBM and nicknamed "Big Blue", is a multinational Computer Technology Fabrik is a visual programming Integrated development environment implemented in Smalltalk and designed at Apple Computer by Daniel Henry Holmes Ingalls Jr is a pioneer of object-oriented Computer programming and the principal architect, designer and implementor of Higher level construction of user interfaces was evidenced by other tools such as Jean Marie Hulot's interface builder first done in Lisp and then evolved to become the NeXT interface builder tool in NeXTStep which allowed for building user interfaces by WYSIWYG composition of UI widgets which could be "wired" to each other and to application logic written in Objective-C. NeXT Computer Inc (later NeXT Software Inc) was an American Computer company headquartered in Redwood City, California that Objective-C is a reflective, object-oriented Programming language which adds Smalltalk -style messaging to C. The original prototype which led to VisualAge was the implementation of an interface builder like tool within the Smalltalk/V development environment. Smalltalk is an object-oriented, dynamically typed, reflective programming language. By the time VisualAge was released as a product, much more emphasis was placed on visual construction of application logic as well as of the user interface. This emphasis was in part due to the "positioning" for "strategic" reasons of Smalltalk as a generator rather than a language within IBM's System Application Architecture. Systems Application Architecture ( SAA) is a set of standards for Computer software, developed by IBM in the 1980s and implemented in IBM

The VisualAge Name

The name VisualAge was the result of a contest between the members of the development team. After the initial release of VisualAge/Smalltalk the name VisualAge became a brand of its own and VisualAges were produced for several different combinations of languages and platforms.

Evolution

Most of the members of the VisualAge family were written in Smalltalk no matter which language they supported for development. In Computer programming, BASIC (an Acronym for Beginner's All-purpose Symbolic Instruction Code) is a family of High-level programming languages COBOL (ˈkoʊbɒl is one of the oldest programming languages still in active use tags please moot on the talk page first! --> In Computing, C is a general-purpose cross-platform block structured C++ (" C Plus Plus " ˌsiːˌplʌsˈplʌs is a general-purpose Programming language. EGL (Enterprise Generation Language is a high level modern business oriented programming language designed by IBM to be platform independent Fortran (previously FORTRAN) is a general-purpose, procedural, imperative Programming language that is especially suited to IBM VisualAge Pacbase is a code-switching Structured programming language that is developed and maintained by IBM. PL/I ("Programming Language One" ˌpiːˌɛlˈwʌn is an imperative computer Programming language designed for scientific engineering RPG is a Programming language for business applications Originally an initialism for Report Program Generator, it officially no longer stands for anything TPF is an IBM Real-time operating system for mainframes descended from the IBM System/360 family including ZSeries and System Smalltalk is an object-oriented, dynamically typed, reflective programming language. OS/2 is a computer Operating system, initially created by Microsoft and IBM, then later developed by IBM exclusively IBM i is an Operating system used on IBM Power Systems, a unified server platform from the former IBM System i and IBM System p servers IBM i is an Operating system used on IBM Power Systems, a unified server platform from the former IBM System i and IBM System p servers Linux (commonly pronounced ˈlɪnəks Mac OS is the trademarked name for a series of Graphical user interface -based Operating systems developed by Apple Inc Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. z/OS is a 64-bit Operating system for Mainframe computers, created by IBM. OS/390 is an IBM Operating system for the System/390 IBM mainframe computers. Multiple Virtual Storage, more commonly called MVS, was the most commonly used Operating system on the System/370 and System/390 IBM z/VSE (Virtual Storage Extended is an Operating system for IBM mainframe computers the latest one in the DOS/360 lineage, which originated in 1965 The IBM implementation of Smalltalk was produced by Object Technology International which was acquired by IBM and run as a wholly owned subsidiary for several years before being absorbed into the overall IBM organization. Object Technology International (OTI was founded in 1988 and acquired by IBM in 1996

VisualAge for Java was based on an extended Smalltalk virtual machine which executed both Smalltalk and Java byte codes. In Computer science, a virtual machine (VM is a Software implementation of a machine (computer that executes programs like a real machine Bytecode is a term which has been used to denote various forms of Instruction sets designed for efficient execution by a software interpreter as well as being suitable Java natives were actually implemented in Smalltalk.

VisualAge Micro Edition, which supported development of embedded Java applications and cross system development, was a reimplementation of the IDE in Java. This version of VisualAge morphed into the Eclipse Framework. In Computing, Eclipse is a Software platform comprising extensible Application frameworks tools and a Runtime library for Software

VisualAge is no longer available. Various members of the family have been replaced by products in the WebSphere Studio family of products. Headline text == WebSphere refers to a Brand of IBM software products that are mostly proprietary, although the term The original VisualAge product (VisualAge for Smalltalk) was licensed by IBM to Instantiations, and the current version is called VA Smalltalk. The C, C++ and Fortran compiler on AIX, Linux and z/OS are renamed as XL compiler series.
