PLDB: MSG.84
Introduction
MSG.84 is a programming language that first appeared in 1985. Though details about its creators and many aspects of its history remain unclear, it is recognized as part of the academic community, particularly tied to the University of Minnesota. The language does not have significant contributions to online repositories, and there is little information about its source code or any associated projects on platforms like GitHub.

History
MSG.84 emerged in 1985, during a time when many specialized and experimental programming languages were being developed in academic settings. The University of Minnesota, known for its contributions to research and technological development, was the central institution behind the creation of MSG.84. However, there is a lack of comprehensive documentation about the initial purpose of MSG.84 or its impact on the programming community at large.
Features
MSG.84’s feature set is not well documented in terms of modern standards. It does not appear to have widespread support for some of the common features found in contemporary programming languages, such as comments or semantic indentation. Specific details about these features are not available, and it seems that MSG.84 might have been more of a niche or experimental language rather than one meant for large-scale adoption.
-
Comments: There is no clear information on whether MSG.84 supports comments. This would be an unusual limitation for any programming language but is a possibility, given the lack of documentation.
-
Semantic Indentation: Similarly, no information has been provided about whether MSG.84 offers features related to semantic indentation, which is a common feature in modern programming languages to improve code readability.
-
Line Comments: The language does not seem to support line comments, which is a basic feature in most programming languages today.
Repository and Community
The language does not appear to have any significant presence in online repositories or community-driven platforms like GitHub. The central package repository count is listed as zero, indicating that the language has not been widely adopted or maintained by the open-source community.
The origin community is identified as the University of Minnesota, but there are no available resources or active groups discussing MSG.84 today. The absence of documentation and development activity suggests that MSG.84 may not have seen much use beyond its initial academic context.
Conclusion
MSG.84 remains a largely obscure and unremarkable programming language. While its ties to the University of Minnesota suggest an academic origin, the lack of widespread adoption or detailed documentation has relegated it to relative obscurity. Modern programming languages with robust feature sets, like support for comments, indentation, and active open-source repositories, have long since surpassed MSG.84 in terms of functionality and usability.
