Procedure and function overloading is used for procedures/functions with the same name/functionality but accepting different data types; good examples of this are found in the dbmssql.sql script (among others) found at $ORACLE_HOME/rdbms/admin (on UNIX; on NT/2000/98 it will be under the RDBMS\ADMIN or RDBMS80\ADMIN directory under the Oracle installation directory). I don't believe you can overload a function/procedure when you have the same datatype between the two versions.
