Page "Array data structure" Paragraph 7

The first digital computers used machine-language programming to set up and access array structures for data tables, vector and matrix computations, and for many other purposes.

Von Neumann wrote the first array-sorting program ( merge sort ) in 1945, during the building of the first stored-program computer .< sup > p.

Some mainframes designed in the 1960s, such as the Burroughs B5000 and its successors, had special instructions for array indexing that included index-bounds checking ..
