  This paper chronicles the adoption and adaptation of APL in the Soviet Union up to 1991. Initially hampered by hardware limitations and the lack of official support, APL gained a foothold through enthusiastic individuals who saw its potential for scientific computing and education. The development of Soviet APL interpreters, notably on ES EVM mainframes and personal computers like the Iskra-226, fostered a growing user community. Despite challenges like Cyrillic character adaptation and limited access to Western resources, Soviet APL users formed active groups, organized conferences, and developed specialized applications in various fields, demonstrating a distinct and resilient APL subculture. The arrival of perestroika further facilitated collaboration and exchange with the international APL community.

  This 1991 paper, "A History of APL in the USSR," meticulously chronicles the introduction, adoption, and evolution of the APL programming language within the Soviet Union, painting a picture of a vibrant, albeit isolated, community of users and developers. The narrative begins in the late 1960s, a period marked by the Iron Curtain and restricted access to Western technology. Despite these limitations, the inherent power and conciseness of APL, particularly its suitability for scientific and mathematical computations, captured the attention of Soviet academics and researchers.

  The initial exposure to APL within the USSR happened through limited channels like published literature and occasional international conferences. This scarcity of direct access fostered an environment of independent implementation and adaptation. The authors describe the development of several indigenous APL dialects, each tailored to the specific hardware limitations and computational needs of the time. These included interpreters designed for mainframe systems like the BESM-6 and Minsk-32, often lacking the full functionality of their Western counterparts but nonetheless enabling crucial research and development within the Soviet Union.

  The paper details the painstaking process of creating these APL implementations, often involving manual translation of algorithms and adaptation to the Cyrillic alphabet. This period of independent development fostered a deep understanding of the language's underlying principles and contributed to a unique flavor of APL within the Soviet context. The authors highlight the dedication and ingenuity of the early Soviet APL pioneers who overcame significant obstacles to bring this powerful tool to their research communities.

  As the narrative progresses into the 1970s and 80s, the paper explores the emergence of localized APL communities. These groups, often centered around specific research institutions or universities, facilitated the exchange of knowledge, software, and experiences, playing a crucial role in disseminating APL throughout the Soviet Union. The authors underscore the importance of these informal networks in overcoming the limitations imposed by the political and technological landscape.

  The paper also touches on the challenges faced by the Soviet APL community. The restricted access to Western hardware and software, combined with the inherent complexity of the language itself, presented significant hurdles to wider adoption. Furthermore, the lack of official support and standardization hindered the development of robust and portable APL applications.

  Despite these challenges, the authors depict a resilient and enthusiastic community of APL users within the USSR. They highlight the significant contributions made by Soviet researchers in areas like mathematical modeling, scientific computation, and data analysis, all powered by the unique capabilities of APL.

  Finally, the paper concludes with a glimpse into the future of APL in the post-Soviet era, anticipating the potential for greater collaboration and integration with the international APL community. The authors express optimism that the lifting of restrictions and increased access to Western technology will usher in a new era of growth and innovation for APL within the former Soviet Union, allowing the Soviet APL community to finally connect with and contribute to the wider global APL ecosystem.
