C DESCRIPTION:
C OpenMP Example - Combined Parallel Loop Reduction - Fortran Version
C This example demonstrates a sum reduction within a combined parallel loop
C construct. Notice that default data element scoping is assumed - there
C are no clauses specifying shared or private variables. OpenMP will
C automatically make loop index variables private within team threads, and
C global variables shared.
