20 C | SUBROUTINE forward_step
21 C | o Run the ocean model and, optionally, evaluate a cost function.

24 C | THE_MAIN_LOOP is the toplevel routine for the Tangent Linear and
25 C | Adjoint Model Compiler (TAMC). For this purpose the initialization
26 C | of the model was split into two parts. Those parameters that do
27 C | not depend on a specific model run are set in INITIALISE_FIXED,
28 C | whereas those that do depend on the specific realization are
29 C | initialized in INITIALISE_VARIA.

88 C note: under the multi-threaded model myiter and
89 C mytime are local variables passed around as routine
90 C arguments. Although this is fiddly it saves the need to
91 C impose additional synchronisation points when they are
92 C updated.
93 C myIter - iteration counter for this thread
94 C myTime - time counter for this thread
95 C myThid - thread number for this instance of the routine.
