FORTRAN 77 on PDP-11

[Dwight K. Elvey]

Hi
 For those that are interested in such things, they
have found a formula to calculate any digits of
PI. The only problem seems to be that it can only
do this for the Hexadecimal digits and not the
decimal digits. They are still looking for an equation
that will do it for decimal digits.
 This can be used to verify ones PI calculations.
I saw the formula in a Science News about 2 years ago.
