John,
Try this (Taken from Surfer 7 help file )
The Atlas BNA file is used to store geographic information including areas, curves,
and points. This format is not commonly used in Surfer.
Alternate BNA Format
"Pname 1", "Sname 1", type/length, x1, y1, x2, y2, x3, y3, ... xn, yn
"Pname 2", "Sname 2", type/length, x1, y1, x2, y2, x3, y3, ... xn, yn
Examples of the format for different objects:
Example 1:
This is an example of a polygon. The polygon has both a Primary and Secondary ID.
