They don't make 'em like that any more: Borland Turbo Pascal 7

The speed and simplicity of Borland Turbo Pascal 7's development tools are no longer available for modern systems.

Borland's Turbo Pascal 7 (TP 7), also known as Turbo Pascal for Windows 1.5, was the final and most advanced version of the highly successful Turbo Pascal line. Introduced in the 1990s, it revolutionized Windows programming by providing an integrated development environment (IDE) that included source-level debugging and graphical tools for user interface design. TP 7's efficiency, stemming from its design for resource-constrained CP/M and MS-DOS systems, made it remarkably fast on the more powerful Windows 3.1 platform. This ease of use and powerful feature set, including the Object Windows Library for object-oriented programming, attracted many developers, contributing to the widespread adoption of Windows. Despite its impact, Turbo Pascal eventually declined due to increased competition from C programming languages, improvements in Microsoft's own C tools, and the rise of easier-to-use languages like Visual Basic.

The legacy of Borland Turbo Pascal 7 highlights a critical juncture in software development where highly optimized, resource-efficient tools enabled widespread adoption of new operating systems like Windows. Its success demonstrated the power of integrated development environments and object-oriented programming libraries, setting benchmarks that influenced subsequent developer tools. The shift away from such specialized, efficient tools toward more resource-intensive, albeit feature-rich, environments reflects changes in hardware capabilities and developer skill expectations. This transition may have inadvertently contributed to a perceived decline in software development craftsmanship as complexity shifted from programmer skill to tool capabilities.

The reasons for Turbo Pascal's decline—competition from C, Microsoft's platform control, and the rise of simpler languages like Visual Basic—underscore the dynamic nature of the software market, where technical merit must align with ecosystem and market pressures. Borland's inability to maintain its competitive edge in this evolving landscape, despite a superior product at the time, serves as a case study in platform dependency and strategic product evolution. The author's reflection on the potential loss of highly skilled development practices due to increased computational power and AI suggests a potential future concern about the depth and efficiency of software creation.
