Understanding the Field Class
A field object, instantiated from the field class, is a single instance of data within a record object, and is based on a field definition.
Accessing or changing the value of a field using the Value property is a common action.
SetDefault is a frequently used method. Name, Enabled, and Type are several commonly used field properties. If you are working with message objects, EditError is also a commonly used field property.
The field class is one of the data buffer access classes.
All of the field properties related to the user interface, such as the Label property, only return the value previously set in PeopleCode (false, or blank if nothing was set). They do not return the values set for the field in Application Designer.
