Non-English-based programming languages

Prevalence of English-based programming languages
There has been an overwhelming trend in programming languages to use the English language to inspire the choice of keywords and code libraries. According to the HOPL online database of languages, out of the 8500+ programming languages recorded, roughly 2400 of them were developed in the United States, 600 in the United Kingdom, 160 in Canada, and 75 in Australia.
In other words, over a third of all programming languages were developed in a country with English as the primary language. This does not take into account the usage share of each language, situations where a language was developed in a non-English-speaking country but used English to appeal to an international audience (see the case of Python from the Netherlands, or Ruby from Japan, or Lua from Brazil), and situations where it was based on another language which used English (see the case of Caml, developed in France but using English keywords).
International programming languages
ALGOL 68's standard was published in numerous languages, and the standard allowed the internationalisation of the programming language itself.
On December 20, 1968, the "Final Report" (MR 101) was adopted by the Working Group, then subsequently approved by the General Assembly of UNESCO's IFIP for publication. Translations of the standard were made for Russian, German, French, Bulgarian, and then later Japanese. The standard was made available in Braille. ALGOL 68 went on to become the GOST/ГОСТ-27974-88 standard in the Soviet Union.
- GOST 27974-88 Programming language ALGOL 68 - Язык программирования АЛГОЛ 68
- GOST 27975-88 Programming language ALGOL 68 extended - Язык программирования АЛГОЛ 68 расширенный
In English, Algol68's reverent case statement reads case ~ in ~ out ~ esac. In Cyrillic, this reads выб ~ в ~ либо ~ быв.

They do not just change the keywords but also the grammar to match the language.
