The BASIC Era: GW-BASIC, QBasic, and QuickBasic in the 80s and 90s

For many who started their computing journey in the 1980s and 1990s, BASIC was the gateway to programming. This family of languages, initially designed for beginners, evolved significantly during these two decades, shaping a generation of budding developers and game creators. Among the most prominent dialects were GW-BASIC, QBasic, and QuickBasic, each marking a step forward in accessibility and capability. Developers like “Viper,” the author behind “OK GAMES,” often got their start with these very tools, learning the ropes from a young age.

GW-BASIC: The Ubiquitous Interpreter

GW-BASIC (Microsoft GW-BASIC) was Microsoft’s enhanced version of the original Dartmouth BASIC, primarily bundled with MS-DOS systems. It was an interpreted language, meaning that each line of code was translated and executed on the fly. This made it incredibly easy for beginners to write and test simple programs, as they could see immediate results without a lengthy compilation process.

However, its interpreted nature also meant it was relatively slow, especially for graphics-intensive applications or games. Programs written in GW-BASIC often relied on line numbers (e.g., 10 PRINT "HELLO") and were known for their somewhat unreadable “spaghetti code” if not carefully structured. Despite these limitations, GW-BASIC was the first taste of programming for millions, enabling simple text-based games, utilities, and graphical experiments using commands like SCREEN, COLOR, LINE, and CIRCLE.

QBasic: The Structured Leap

With the release of MS-DOS 5.0 in the early 1990s, Microsoft introduced QBasic (QuickBasic Extended Application for Students), often replacing GW-BASIC as the default BASIC interpreter. QBasic was a significant upgrade, offering an integrated development environment (IDE) with a blue-screen editor, syntax highlighting, and a built-in debugger.

Crucially, QBasic encouraged structured programming by making line numbers optional and introducing procedures (SUBs) and functions (FUNCTIONs). This allowed for more organized and readable code, which was a huge step forward for larger projects. While still primarily an interpreter, QBasic was faster than GW-BASIC and provided better support for graphics modes and limited sound capabilities. It became a staple in educational settings, helping students transition from simple scripts to more complex, modular programs.

QuickBasic: The Compiler’s Power

QuickBasic (Microsoft QuickBasic) was the professional, commercial version of QBasic. While sharing a similar IDE and syntax with QBasic, its defining feature was the ability to compile programs into standalone .EXE executables. This meant that QuickBasic programs could run much faster than their interpreted counterparts, as the entire code was translated into machine language once, before execution.

QuickBasic also offered more advanced features for its time, including better memory management, access to more graphics modes, and the ability to link with external libraries written in other languages (like C or Assembly) to extend its capabilities, particularly for demanding tasks like game development. This made it a favorite among hobbyist game developers who wanted to create more sophisticated titles without diving into the complexities of C or Assembly directly. Games built with QuickBasic could achieve smoother animations, more detailed graphics, and more complex logic than was easily possible with GW-BASIC.

A Brief Timeline

• 1983: GW-BASIC is released, becoming the standard BASIC interpreter for many DOS systems.
• 1985: Microsoft introduces QuickBasic 1.0, bringing compilation capabilities and an IDE.
• Early 1990s: QBasic is bundled with MS-DOS 5.0, becoming the default interpreter for many users, offering a more structured approach than GW-BASIC.
• Late 1980s – Early 1990s: QuickBasic continues to evolve through versions like 4.5, becoming a popular choice for hobbyists and shareware game developers.

The Legacy Through Viper’s Eyes

For many, including Viper, the author of OK GAMES ! these BASIC dialects weren’t just programming tools; they were creative playgrounds. Growing up in this era, a young Viper likely started with GW-BASIC’s simplicity, then moved to QBasic’s structured approach, and perhaps eventually embraced QuickBasic’s compilation power to create more ambitious projects. These languages provided an accessible entry point into the world of software development, allowing individuals to translate their ideas directly into playable experiences on their home PCs. They were the building blocks of early PC gaming and a crucial stepping stone for many who later pursued careers in software or game design.

The simplicity, accessibility, and steady evolution of GW-BASIC, QBasic, and QuickBasic made them cornerstones of early personal computing, leaving an indelible mark on both technology and the generation of developers they inspired.
