      ** PURPOSE: This sample program demonstrates the use of LOB values. 
      **          The program creates a CURSOR, and fetches the contents 
      **          of the "emp_resume" table (the SAMPLE database must be 
      **          installed with teh "db2sampl" executable), and then 
      **          outputs the first 15 lines of the resume. 
      ** 
      ** For more information about these samples see the README file. 
      **
