NPL: A Legacy in Computing
NPL (New Programming Language) was introduced in 1963 as a project by IBM, reflecting the era’s growing interest in creating more powerful and user-friendly programming languages. Despite the brief existence of NPL, its inception marked an important step in the evolution of programming languages.
Background
NPL was developed in the early 1960s, a time when the programming world was evolving rapidly. The language, however, was not as widely known or used as other contemporaneous languages like COBOL or FORTRAN, which were more prevalent in the industry. NPL’s brief presence in the field didn’t overshadow its potential in influencing later programming language designs.

Features and Characteristics
The most notable feature of NPL was its strong theoretical foundation, inspired by IBM’s research into programming and automation. Although there is little concrete information about the technical specifics of NPL, it is often remembered for its advanced design concepts, especially in terms of its potential application in business automation systems.
One of the key challenges NPL faced was its lack of widespread adoption, despite its innovative features. The language did not have built-in support for comments or semantic indentation, which were becoming essential in programming languages of that era. The absence of features like line comments, which have since become fundamental to readability and maintenance in code, further limited NPL’s appeal.
Community and Legacy
Despite its limited usage, NPL’s connection to IBM ties it to one of the most significant players in the computer industry. As IBM continued to advance the field of computing, NPL’s influence was felt in other programming languages that followed. It served as an experimental ground for exploring language design, even though its development was ultimately not sustained.
Is NPL Open Source?
There are no records indicating whether NPL was released as open source, and it did not maintain a public repository like many modern programming languages. With no available information about its GitHub presence, it remains unclear whether the language was ever shared with the wider programming community in such a manner.
Conclusion
In conclusion, NPL’s role in the history of programming languages remains niche but important. Introduced at a time of significant transition in the world of computing, its design ideas contributed to the broader conversation about how programming languages should evolve. Although it didn’t achieve mainstream use, NPL provided valuable lessons that continue to shape modern programming practices.
