Comrie uses punched card machines to calculate the motions of the moon. This project, in which 20,000,000 holes are punched into 500,000 cards continues into 1929. It is the first use of punched cards in a purely scientific application. [36]

For Jacquard looms, the resulting punched cards were joined together to form a paper tape, called a "chain", containing a program that, when read by a loom, directed its operation. [1] For Hollerith machines and other unit record machines the resulting punched cards contained data to be processed by those machines.
