C CALCULATES THE DISTANCE BETWEEN TWO POINTS IN CARTESIAN SPACE
Double Precision FUNCTION DIST(A,B)
IMPLICIT DOUBLE PRECISION (A-H,O-Z)
DIMENSION A(3),B(3)
cYAU - I warn you, expanding all of these out does not ensure Z is positive.
Z= (A(1)-B(1))**2
Z=Z+(A(2)-B(2))**2
Z=Z+(A(3)-B(3))**2
DIST = SQRT(Z)
RETURN
