+/******************************************************************************
+* OpenMP Example - Combined Parallel Loop Work-sharing - C/C++ Version
+* FILE: omp_workshare4.c
+* DESCRIPTION:
+*   This is a corrected version of the omp_workshare3.c example. Corrections
+*   include removing all statements between the parallel for construct and
+*   the actual for loop, and introducing logic to preserve the ability to 
+*   query a thread's id and print it from inside the for loop.
+* SOURCE: Blaise Barney  5/99
+* LAST REVISED: 03/03/2002
