+C FILE: omp_workshare1.f
+C DESCRIPTION:
+C   OpenMP Example - Loop Work-sharing - Fortran Version
+C   In this example, the iterations of a loop are scheduled dynamically
+C   across the team of threads.  A thread will perform CHUNK iterations
+C   at a time before being scheduled for the next CHUNK of work.
