Field help (ATBCODZONE) 

Define the field name for the table as it will be expressed in the software. A field with the name FIELDNAME defined in an ABV abbreviation table can be accessed using the [F:ABV]FIELDNAME syntax.

For custom/specific fields, the field name must start with X_, Y_, or Z_.

In the database, each zone corresponds to one or more fields, according to whether or not the zone is sized. The corresponding fields are called FIELDNAME_0, FIELDNAME_1, FIELDNAME_2.

To enter and display the corresponding field on a screen, it is given the same name in the screen dictionary. The screen and the table will be used simultaneously in object management.
