If a particular object has the same name as another object of a different type (for example, if a field is named First_Name and a variable is also named First_Name), 4D uses a priority system to identify the object. It is up to the programmer to ensure that unique names are used. 4D identifies names used in methods in the following order:

Fields

1. Commands
   
2. Methods
   
3. Plug-in routines
   
4. Predefined constants
   
5. Variables
