- * (A) - Some enumerations are implicitly declared inside a VAR ... END_VAR declaration

- * These enumvalueX will only be valid (in scope) inside the POU in which the enum_var is declared.
- * Because of this, they are not stored in this symbol table

- * (B) - if the value is defined multiple times the value is the null pointer.

- * (C) - The stored symbol_c * associated to the value points to the enumerated_type_name
- * (i.e. the name of the enumerated data type) in which the the value/identifier is used/declared.
- *
- * (D) - We could re-use the null_symbol4 object, but it is safer to use a distinct object
- * (i.e. it might make it easier to find strange bugs).
