W-Langage

W-Langage — known in English as WLanguage — is the proprietary programming language at the heart of WINDEV, WEBDEV and WINDEV Mobile, the rapid application development suite published since the early 1990s by PC SOFT of Montpellier, France. It is one of the software industry’s great regional success stories: a language that has never appeared in the TIOBE index’s top 250 and is barely known in the English-speaking world, yet underpins a substantial share of the business software running French companies — and claims, per its publisher, a community of roughly 190,000 professional developers. Its signature feature is genuinely unusual: WLanguage code can be written with French or English keywords (SI...ALORS...FIN or IF...THEN...END), and the IDE can translate a program’s source between the two.

History & Origins

PC SOFT was founded on August 10, 1984 in Montpellier by Patrice Prut, Stéphane Lambert, Gilles Lucato and Jean-Pierre Vignocchi. The young company’s breakthrough was HIGH SCREEN (1986), a screen-interface generator for DOS that let developers design data-entry screens visually and plug them into programs written in various languages; the company reports it sold around 10,000 copies in the United States. That experience — treating the user interface as the starting point of an application rather than an afterthought — became PC SOFT’s defining idea.

When Microsoft Windows made graphical interfaces mainstream, PC SOFT bet the company on a complete development environment of its own. WINDEV 1.0 shipped in 1993 (the W-Langage itself is dated by some sources to around 1992, during the product’s development): an atelier de génie logiciel — the French term for an integrated software engineering workshop — bundling a visual UI editor, a report generator, an integrated database engine (Hyper File, whose descendant is today’s HFSQL), and a new high-level programming language to tie it all together. That language was W-Langage.

The formula worked, particularly in France, where WINDEV became the default tool for a generation of business-software developers. Around the turn of the millennium PC SOFT extended the same language to new targets: WEBDEV (version 1.5 dates from 2001, with version numbering aligned to WINDEV’s in 2003) brought WLanguage to server-side web development, and WINDEV Mobile followed in the 2000s for handheld and mobile devices, today targeting Android and iOS according to PC SOFT’s documentation.

Design Philosophy

WLanguage embodies a philosophy that is easy to caricature and hard to dismiss: the language should read like a business requirement, and the environment should do the plumbing. PC SOFT has marketed it over the years as a fourth- or even fifth-generation language (“5GL”) and famously promises that its tools let you “develop 10 times faster” — a marketing slogan rather than a measured benchmark, but one that captures the intent. Several principles stand out:

• Natural-language readability, in two natural languages. Keywords and the standard library exist in both French and English, and the IDE can automatically translate code between them. A French developer writes Compteur est un entier; an English-speaking colleague reads the same line as Counter is int.
• One language, every target. The same WLanguage code base is shared across WINDEV (Windows desktop — with Linux, .NET and Java targets also described in third-party accounts), WEBDEV (web) and WINDEV Mobile (Android and iOS). Projects and components move between the three products.
• Batteries very much included. WLanguage ships with thousands of built-in functions — from string handling to database access, PDF generation, telephony and web services — and high-level mechanisms such as automatic data binding between UI controls and database fields.
• Data at the center. The bundled HFSQL database engine, the query editor, and the report generator are first-class citizens of the language and IDE, reflecting WINDEV’s focus on gestion — data-oriented business management applications.

The trade-off is lock-in: WLanguage is proprietary, has no independent implementation or standard, and programs can only be created and maintained with PC SOFT’s tools.

Key Features

• Bilingual syntax — French and English keywords for the same language, with IDE-assisted translation of source code between the two.
• Procedural core with object-oriented extensions — WLanguage supports imperative, procedural programming and class-based object orientation.
• Declared, flexible typing — variables are declared with explicit types (X is int, Nom est une chaîne), while the runtime performs many automatic type conversions for the developer.
• Bytecode execution — WLanguage programs compile to bytecode executed by PC SOFT’s runtime virtual machine.
• Enormous built-in standard library — PC SOFT documents thousands of WLanguage functions spanning UI, files, databases, networking, and device features.
• Integrated everything — the language is inseparable from its environment: visual editors, HFSQL database, report writer, installer generator, and lifecycle tooling all ship together.

A flavor of the language’s celebrated party trick — the same tiny program in both syntaxes:

// English keywords
Counter is int
FOR Counter = 1 TO 5
	Info("Hello, World! #" + Counter)
END

// Mots-clés français
Compteur est un entier
POUR Compteur = 1 À 5
	Info("Bonjour tout le monde ! #" + Compteur)
FIN

Evolution

WLanguage has evolved continuously for more than three decades, but almost always in step with its host products rather than as an independently versioned language. PC SOFT settled into an annual release cadence, with each new version of WINDEV, WEBDEV and WINDEV Mobile (version 25 arrived in December 2019, for example) bringing hundreds of advertised new features across the language, IDE and runtimes. Object-oriented programming, web and mobile targets, and ever-larger swaths of the built-in function library were layered onto the procedural core over the years, while the bundled database evolved from Hyper File through HyperFileSQL to today’s HFSQL.

Two recent shifts have been more visible than any language feature. First, with the generation following version 28, PC SOFT adopted year-based branding — WINDEV 2024, 2025, 2026 — in place of sequential version numbers. Second, and far more consequentially, PC SOFT was acquired in late 2024 by Two Squared France II, an acquisition vehicle of Canada’s Constellation Software and its Volaris Group subsidiary (publicly announced by Volaris on May 26, 2025). The new owners completed a transition away from PC SOFT’s traditional perpetual, dongle-protected licenses to a subscription model — a change that has provoked significant unrest in the historically loyal French developer community, including the formation of the Wx Alliance advocacy group and even written questions in the French National Assembly about the acquisition’s economic and security implications.

Current Relevance

WLanguage occupies a paradoxical position. Globally it is a footnote: it has never ranked among TIOBE’s top 250 languages, English-language learning resources are scarce, and its use outside francophone markets is limited. Within France, however, it remains critical infrastructure. Thousands of software houses and IT departments maintain WINDEV code bases running ERPs, point-of-sale systems, medical and logistics applications; PC SOFT and its partners cite organizations from Groupama to Honda France among users of WINDEV-built management software, and the publisher reports a worldwide community of approximately 190,000 professional developers across more than 140 countries (a company figure).

The platform itself is unquestionably alive — the 2026 versions of all three products shipped on December 9, 2025 — but the ecosystem is at an inflection point. The Constellation/Volaris acquisition and the end of perpetual licenses have pushed long-standing questions (vendor lock-in, source-code longevity, pricing control) from theoretical grumbles to existential debate, and how that tension resolves will shape whether new French projects continue to start in WLanguage or only legacy ones remain.

Why It Matters

W-Langage matters for three reasons that have little to do with language theory. First, it is the most successful demonstration that a programming language can thrive in a natural language other than English: its bilingual keyword system remains almost unique among commercially significant languages, and it lowered the barrier to programming for a generation of French developers. Second, it is a case study in the integrated, proprietary RAD model — language, IDE, database, and deployment tooling sold as one inseparable product — a model most of the industry abandoned but which PC SOFT sustained profitably for four decades. And third, its post-acquisition turbulence is a live lesson in the systemic risk of proprietary languages: when your entire application portfolio is written in a language only one vendor can compile, the vendor’s ownership structure becomes your architecture’s single point of failure. For historians of software, WLanguage is what a parallel, non-Anglophone software industry actually looks like — not a curiosity, but tens of thousands of businesses running on SI...ALORS...FIN.
