SQL & PL/SQL

I want create database objects to remote databases using database links and dbms_utility.exec_ddl_statement. How I can refer database links dynamically in oracle stored procedures? It is easy to do in Oracle SQL*plus using SQL:

Example code (SQL script);

SET VERIFY OFF
SET PAGES 0
SET FEEDBACK OFF
SPOOL C:\TMP\REMOTE_TEST.txt

DEFINE MyVar='@MYLINK.WORLD';

EXEC dbms_utility.exec_ddl_statement&MyVar('CREATE TABLE REMOTETEST (COL1 varchar2(20))');

SPOOL OFF
SET VERIFY ON
SET FEEDBACK ON


What about PLSQL and stored procedure?
