% 2.1 Node Coordinates

% File name = ZBC
% File type = binary direct access. Record length = 24 bytes

% One control record, plus one record for each node.

% Control record :
% No. of nodes (integer*4).
% Rest not used.

% Record for each node :
% H1 coordinate (real*8).
% H2 coordinate (real*8).
% V coordinate (real*8).

% Given the coordinates of a node, search this file to obtain the node
% number.
