David, am I misinterpreting this or did Xerox actually suggest that pi
might change? I still have FORTRAN manuals but none for Xerox specifically.

"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."
