High Tech BASIC: A Deep Dive into Rocky Mountain BASIC (RMB)
In the ever-evolving landscape of programming languages, certain dialects and variants stand out due to their specific applications and enduring relevance in particular fields. One such dialect is Rocky Mountain BASIC (RMB), often referred to as High Tech BASIC in certain contexts, which was created by Hewlett-Packard (HP) in the late 1980s. Originally developed as a specialized tool for controlling automatic test equipment, this language has evolved over the decades and remains relevant in certain niches, particularly in environments where investments in software, hardware, and expertise with RMB are already established.
This article explores the origins, features, applications, and lasting influence of Rocky Mountain BASIC, shedding light on its unique contributions to the field of programming languages, especially in relation to automatic test equipment and scientific computing.
The Genesis of Rocky Mountain BASIC
The development of RMB traces back to Hewlett-Packard’s research and development efforts in the 1980s, as they sought to create a versatile and robust programming language suited for controlling automatic test equipment (ATE). At the time, engineers and technicians used GPIB (General Purpose Interface Bus) to interface with test devices. However, there was a need for a programming language that could simplify control of these devices and facilitate complex data processing, all while maintaining efficiency and ease of use.
RMB was created to fulfill this niche. It was designed to be a variant of the BASIC programming language, a popular and accessible language for non-experts and early programmers. However, RMB was engineered to offer capabilities beyond traditional BASIC implementations. It provided built-in support for controlling external devices, handling complex mathematical operations, and facilitating scientific and engineering computations, making it a go-to choice for specific industrial and scientific applications.
Key Features and Functionality
One of the defining aspects of Rocky Mountain BASIC was its extensive external input/output (I/O) support. Test equipment and scientific instruments often require seamless communication with computers for tasks such as data collection, analysis, and reporting. RMB was built with this requirement in mind, making it easier for engineers to interface with a variety of external devices and sensors through the GPIB bus.
Another major feature of RMB was its event-driven operation, a paradigm not commonly found in many BASIC dialects. This feature allowed the language to handle asynchronous events, making it particularly well-suited for applications that require real-time responses. In industrial environments, where systems may be handling multiple processes simultaneously, the ability to respond dynamically to events can be crucial.
RMB also introduced complex number support and matrix manipulation functions, both of which were uncommon in most BASIC dialects at the time. These mathematical capabilities enabled users to perform advanced calculations directly within their programs, without needing to resort to external libraries or custom code.
Moreover, RMB’s support for complex number operations made it ideal for scientific and engineering applications, where such computations are often required in fields such as signal processing, electrical engineering, and physics.
Applications of Rocky Mountain BASIC
In its prime, RMB was predominantly used in automatic test equipment environments. Test systems, particularly in industries like telecommunications, aerospace, and electronics, relied heavily on programming languages that could control complex instruments and process large volumes of data. RMB allowed technicians to create custom scripts for controlling the test equipment, taking measurements, and analyzing the results.
Additionally, RMB was often utilized for applications involving scientific computing and mathematical modeling. The language’s support for matrices and complex numbers made it suitable for a range of calculations in these domains, enabling researchers to perform simulations, analyses, and experiments with ease.
Despite its roots in ATE, RMB was also employed in specialized industrial control systems, where it facilitated automation tasks and real-time data processing. In these scenarios, the language’s event-driven capabilities played a key role, allowing for quick responses to changes in the environment, sensors, or other interconnected systems.
The Decline and Legacy of RMB
Like many specialized programming languages, RMB saw a decline in popularity as the field of test automation evolved and new programming languages with broader support and capabilities gained traction. The advent of more general-purpose languages like Python and LabVIEW provided users with more flexible tools, leading to a reduction in the reliance on RMB for new projects. However, this decline did not mark the end of RMB’s usefulness.
In fact, Rocky Mountain BASIC has remained relevant in many legacy systems. Numerous businesses and research organizations invested heavily in RMB-based software and hardware infrastructure, and as a result, the need for expertise in RMB continues in those environments. Many older test systems, industrial control setups, and scientific experiments still rely on RMB, and engineers with knowledge of the language are essential for maintaining, updating, or troubleshooting these systems.
Furthermore, RMB’s legacy is reflected in its influence on later programming languages designed for scientific and industrial applications. The language’s event-driven nature, combined with its emphasis on mathematical operations and hardware control, paved the way for the development of more modern tools that combine software and hardware integration.
Why RMB Still Matters Today
While RMB is no longer a mainstream language, it retains a niche but important place in the programming ecosystem. For those working in environments where test automation, scientific computation, and hardware interfacing remain crucial, RMB is a valuable tool.
In particular, organizations with significant investments in RMB-based systems, both in terms of software and hardware, continue to benefit from maintaining and updating these systems. Rewriting legacy code or moving to newer platforms would involve considerable time and cost, making it more efficient to keep RMB in use. Additionally, as hardware evolves, RMB’s unique capabilities in controlling complex test equipment ensure that it remains relevant for some applications.
There are also numerous community-driven resources available for those looking to learn more about RMB. Despite its age, some forums, manuals, and legacy documentation still exist, and with the right knowledge, engineers can troubleshoot, adapt, and expand upon existing systems. Moreover, modern-day open-source projects continue to inspire the future of hardware programming, with the unique features of RMB offering valuable lessons for future innovations in test automation and industrial control.
Conclusion
In conclusion, High Tech BASIC (Rocky Mountain BASIC) stands as a testament to the adaptability and niche importance of certain programming languages. Its rise, driven by the needs of Hewlett-Packard and industries requiring precise control over automatic test equipment, highlights the critical role specialized languages can play in technological progress. Even as more modern languages have emerged, RMB continues to hold value in specific sectors, offering a rich set of features and capabilities that cater to a distinct set of needs.
For engineers, scientists, and technicians working with legacy systems, RMB remains a powerful tool. It serves as a reminder of how deeply integrated programming languages can become in specialized industries, leaving a lasting legacy long after the mainstream technology has moved on.
