C *================================================================* |
| 23 |
C | SUBROUTINE the_main_loop |

C | o Run the ocean model and evaluate the specified cost function. |

| 27 |
C | THE_MAIN_LOOP is the toplevel routine for the Tangent Linear and |
| 28 |
C | Adjoint Model Compiler (TAMC). For this purpose the initialization |
| 29 |
C | of the model was split into two parts. Those parameters that do |
| 30 |
C | not depend on a specific model run are set in INITIALISE_FIXED, |
| 31 |
C | whereas those that do depend on the specific realization are |
| 32 |
C | initialized in INITIALISE_VARIA. |
| 33 |
C | This routine is to be used in conjuction with the MITgcmuv |
| 34 |
C | checkpoint 37. |
