Example

The following example opens table 18, the Customer table, a RecordRef variable that is named CustomerRecref. The Field Method (RecordRef) creates a FieldRef for the first field (No.). The reference to the field is stored in the MyFieldRef variable. The Active Method (FieldRef) method determines whether the field is enabled. If the field is enabled, then the record that is identified by the number in the CustomerNo variable is selected. The MyFieldRef variable is updated to refer to the second field (Name). Then the value in the second field is changed to Contoso. The Modify Method (RecordRef) modifies the record in the table to reflect the change. MyFieldRef.Value retrieves the new name and displays it in message box.

var
    MyFieldRef: FieldRef;
    CustomerRecref: RecordRef;
    CustomerNo: Code;
    Text000: Label 'Customer name has changed to %1.';
begin  
    CustomerNo := '50000';  
    CustomerRecref.Open(18);  
    MyFieldRef := CustomerRecref.Field(1);  
    if MyFieldRef.Active then begin  
      MyFieldRef.Value(CustomerNo);  
      MyFieldRef := CustomerRecref.Field(2);  
      MyFieldRef.Value('Contoso');  
      CustomerRecref.Modify;  
      Message(Text000, MyFieldRef.Value);  
    end;  
end;
