**
** SAMPLE: Demonstrates the use of LOB file handles
**
** 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.
**
** SQL STATEMENTS USED:
** BEGIN DECLARE SECTION
** END DECLARE SECTION
** CONNECT
** SELECT
**
** OUTPUT FILE: lobfile.out (available in the online documentation)
