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 lists with allowed operations such as indexing, joining, length count, getting of sublist, easy comparison, etc.
