What Programming Language Did the Commodore VIC-20 Use?

The Commodore VIC-20, a pioneering home computer from the early 1980s, featured a specific built-in programming language that allowed users to create software and games immediately upon startup. This article explores the name of that language, its specific version, and how it empowered a generation of hobbyist programmers to interact directly with the hardware without needing additional tools or compilers.

The built-in programming language on the Commodore VIC-20 was BASIC, which stands for Beginner’s All-purpose Symbolic Instruction Code. Specifically, the machine ran Commodore BASIC V2. This interpreter was stored in the computer’s Read-Only Memory (ROM), meaning it was always available the moment the power was switched on. Users were greeted with the familiar “READY.” prompt, allowing them to type commands directly into the system without loading external software.

Commodore BASIC V2 was designed to be accessible to novices while remaining powerful enough for experienced users. It supported standard programming structures such as loops, conditionals, and subroutines. Beyond standard arithmetic and logic, the language included specific commands to manipulate the VIC-20’s unique hardware features. Users could control sound, graphics, and memory addresses directly using commands like POKE and PEEK, which made it a favorite for creating simple games and utilities.

The inclusion of BASIC in ROM was a standard practice for home computers of that era, but the VIC-20’s implementation was particularly significant due to the machine’s affordability. It became many people’s first introduction to coding, fostering a community of users who shared type-in programs from magazines. This accessibility helped democratize computer programming, turning the VIC-20 into an educational tool as much as a gaming console.

Today, the legacy of the VIC-20’s programming language remains a notable chapter in computing history. While modern systems rely on complex integrated development environments and compiled languages, the immediate feedback loop of Commodore BASIC V2 provided a hands-on learning experience. The language served as the foundation for countless developers who began their careers typing simple print commands on this iconic 8-bit machine.
