COBCH1747 Only properties and events allowed in interface data division.

A data item that is not declared as a property or event has been declared in the data division.

Resolution:

Remove the data item from the data division, or recode it as a property or event; then recompile.

Example:

In the following example, the MyString definition is neither a property nor an event and is therefore not allowed.

       interface-id IMyInterface.
       01 MyString string public.
       end interface.
