C | THE_MAIN_LOOP is the toplevel routine for the Tangent Linear and |

| 27 |
C | not depend on a specific model run are set in INITIALISE_FIXED, |

C ===== |
| 531 |
C Because of the ordering of the timestepping code and |
| 532 |
C tendency term code at end of loop model arrays hold |
| 533 |
C U,V,T,S at "time-level" N but gu, gv, gs, gt, guNM1,... |
| 534 |
C at "time-level" N+1/2 (guNM1 at "time-level" N+1/2 is |
| 535 |
C gu at "time-level" N-1/2) and etaN at "time-level" N+1/2. |
| 536 |
C where N = I+timeLevBase-1 |
| 537 |
C Thus a checkpoint contains U.0000000000, GU.0000000001 and |
| 538 |
C etaN.0000000001 in the indexing scheme used for the model |
| 539 |
C "state" files. This example is referred to as a checkpoint |
| 540 |
