    если n = 0 то
        возврат 0
    все
    если n = 1 то
        возврат 1
    все
    возврат фибоначи(n - 1) + фибоначи(n - 2)
конец

values := <* *>
для i от 0 до 10 цикл
    values := values + <* фибоначи(i) *>
кц

вывод: values      \ Prints <* 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 *>

FAQ

What is Rapira?

Rapira (Рапира) is a programming language that was created in the Soviet Union during the 1980s. It was originally designed by Gennady Anatolievich Zvenigorodsky [1].

The original implementation of Rapira was part of Schoolgirl (Shkolnitsa) [1], an educational software system created at the Computing Center of the Siberian Branch of the USSR Academy of Science in Novosibirsk. [2, 3] The Schoolgirl system was developed “in late 1984 by a group of young graduates of the Young Programmers School, mentored by G. Zvenigorodski under the guidance of Andrei Ershov” and accompanied a course meant to teach “the basics of informatics and computing machines.” [2] It supported two languages, Robic and Rapira, used to teach programming to “children from 2nd to 10th grades.” [3]

What computers was Rapira originally used on?

Rapira interpreters existed for the Agat, Korvet, and an unspecified Yamaha computer. [1]

What languages does Rapira support?

Russian, English, and Moldovan variants of Rapira were developed. [1] Rapture only supports the English and Russian variants.
