'''Rapira''' ({{langx|ru|Рапира}}, rapier) is an educational [[procedural programming]] language developed in the Soviet Union and implemented on the [[Agat (computer)|Agat]] computer, [[PDP-11]] clones (Electronika, DVK, BK series), and [[Intel 8080]] and [[Zilog Z80]] clones (Korvet). It is [[Interpreter (computing)|interpreted]] with a [[dynamic type]] system and [[High-level programming language|high level]] constructions. The language originally had a [[Russian language|Russian]]-based set of [[reserved word]]s (keywords), but English and [[Romanian language|Romanian]] were added later. It was considered more elegant and easier to use than [[Pascal (programming language)|Pascal]] implementations of the time.{{According to whom|date=October 2015}}

Rapira was used to teach [[computer programming]] in Soviet schools. The [[integrated development environment]] included a text editor and a debugger.

Sample program:
 ПРОЦ СТАРТ()
     ВЫВОД: 'Привет, мир!!!'
 КОН ПРОЦ

The same, but using the English lexics [sic, from the article referenced below]:
 proc start()
      output: 'Hello, world!!!';
 end proc

Rapira's ideology was based on languages such as [[POP-2]] and [[SETL]], with strong influences from [[ALGOL]].

Consequently, for example, Rapira implements a very strong, flexible, and interesting data structure, named a ''[[tuple]]''. in Rapira, these are heterogeneous [[List (abstract data type)|lists]] with allowed operations such as indexing, joining, length count, getting of sublist, easy comparison, etc.
