The Additional code tab is displayed on the object page only if the Additional code checkbox is selected on the Additional tab in the Program settings section.
On this tab (Figure 1), you can write additional C# code. Typically, the code on this tab is used to implement the interfaces used in the current object. These interfaces are specified on the object page on the Additional tab > in the Program settings section > in the Implemented interfaces field. Also, on the Additional code tab, obsolete properties are specified (Figure 1), which were used earlier. This code allows the script to work correctly.
