A fragment of the program written in Rapira on the Agat computer.

Rapira (Rosapi Rapa) is an educational procedural programming language created in the 1980s in the USSR and implemented in a BESM-6 computer, then in the first Soviet PC Agat and PDP-11 clones (Electronics DVK, Electronics BK) and clones Intel-8080 / Z80 (Corvette). Rapira was a language interpreted with a dynamic type system and a high level of construction. Originally, the language was based on a Russian set of words, but later also English and Moldovan sets were added. Rapira was a language much easier to use than the then implementations of the Pascal language.

Rapira was used to learn computer programming in Soviet schools as part of the "Szkolnica" program. The programming environment included a text editor, integrated debugger, Rapira language interpreter, Robik language interpreter, graphical "Szpaga" system, a set of typical mathematical functions, a set of example programs for various school subjects.

Sample program: PROC START (); CONCLUSION: "HELLO, PEACE!"; KSC;

Same, but using English vocabulary: proc start(); output: "Hello, world!!!"; end;

The Rapir language ideology was based on such languages ​​as POP-2, SETL or ALGOL.

The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler. The fragment of the Megasthenes (IV-III century BC) preserved in fragments can be seen in the underground mines at the foot of the mountains on the easte...
