Changing a field name  
How to change a field name To change a field name, simply navigate to the name row for the desired field (by arrow keys or mouse) and enter the new name. Press ENTER when done or exit the field.

Field names must start with an alphabetic character (A-Z) and contain only alphabetics, numbers, or an underscore character. The maximum field length for a name is 127. If you enter spaces in a field name, the system will automatically convert them to underscores. If you enter an invalid name the system will restore the name to the previous value.

When you save a file, the system will check for duplicate field names.
