Apparently the Fortran language has a DATA statement just for this purpose. This is allegedly a quote from an early Fortran manual: The primary purpose of the DATA statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable PI can be given that value with a DATA statement and used instead of the longer form of the constant. This also simplifies modifying the program, should the value of pi change.
