Lexicon (program)

Lexicon was a text editor / word processor MS-DOS program that was extremely popular in the Soviet Union and Russia at the end of 1980s and in 1990s.

Later Windows versions were developed, but they were not popular, due to easily available pirated copies of Microsoft Word.

Lexicon was originally developed at the Computing Center of the Academy of Sciences of the USSR by Ye. N. Veselov.

Lexicon could produce and edit plain text files; at the same time, it could enrich them with various formatting codes (which all started with the character 255 (0xFF)).

Lexicon could work with both osnovnaya (primary) and alternativnaya (alternative) character sets.
