Copenhagen is a city in Europe.
In the matrix[]
According to Flatline, the jumbled fringes of the low-security university section of Copenhagen are a pirate's paradise. There is a board with confused outlines of arts faculties, over which pirates write stolen codes with glyphs with shimmering colorful light. Each day the companies read the board and change their codes, and same story is repeated.
Dixie Flatline gave to Case the coordinates to see the entry code for Bell Europa, so that he could enter Armitage's database in London.
