Use column names in a point file format to specify which point information is included in a point data file.
When creating a new point file format, you are presented with a list of unused columns:
Specify the contents of the first column in the point data file by clicking the first column heading and specifying a point property, for example, Easting, in the Point File Formats - Select Column Name dialog box. The first column heading is updated to reflect the specified column name:
Specify the contents of the second column in the point data file by clicking the second column heading in the dialog box and specifying another point property, for example, Northing:
Continue to specify column headings until the point file format column names reflect the layout of the point data file.
Some point file format columns can be used to perform calculations when they are included in the format. For more information, see Using Point File Format Properties to Perform Calculations.
