RECURSIVE_SUB_TEST
  FORTRAN90 version.
 
  Demonstrate recursive subroutine definitions.
 
  We sort a vector by recursion.
  Our recursive step finds the largest element and moves
  it to the end.
 
  Unsorted vector:
 
         1            10
         2             8
         3             6
         4             6
         5            10
         6             3
         7             6
         8             1
         9             4
        10             6
 
  Sorted vector:
 
         1             1
         2             3
         3             4
         4             6
         5             6
         6             6
         7             6
         8             8
         9            10
        10            10
 
RECURSIVE_SUB_TEST:
  Normal end of execution.
