Yorick is an interpreted programming language. With Yorick you can read input (usually lists of numbers) from virtually any text or binary file, process it, and write the results back to another file. You can also plot results on your screen.

Yorick expression and flow control syntax is similar to the C programming language, but the Yorick language lacks declaration statements. Also, Yorick array index syntax more closely resembles Fortran than C.
