SAKO (programming language) explained

Paradigm:	Multi-paradigm structured, imperative (procedural), array

SAKO (PL: System Automatycznego KOdowania^[3] - EN: An Automatic Coding System^[4]) is a Polish language-based programming language written in years 1959-1960 by a team from ZAM division of Polish Academy of Sciences.^[5] Originally developed for the computers XYZ and ZAM-2, in later years also for ZAM-21, ZAM-41 and Mińsk-22.^[6]

General features of the SAKO language:

commands similar to sentences used in natural language
shortened the time of learning the principles of programming
easy to use, reduced coding time
transparent program code, low probability of making a mistake

It had a static address allocation. It was possible to insert code in SAS macro assembler. The compilation proceeded in two stages:

From SAKO to simplified SAS macro assembler (SAS-W).
From SAS-W to machine language.

The most characteristic feature of SAKO are Polish commands, e.g. CZYTAJ, SKOCZ DO. Designed primarily for programming numerical calculations.
