C !DESCRIPTION: |

C *==========================================================* |
| 20 |
C | SUBROUTINE EXCH_UV_3D_RX |
| 21 |
C | o Handle exchanges for _RX, 3-dimensional vector arrays. |
| 22 |
C *==========================================================* |
| 23 |
C | Vector arrays need to be rotated and interchaged for |
| 24 |
C | exchange operations on some grids. This driver routine |
| 25 |
C | branches to support this. |
