A continue run is an exact continuation of a previous run. This means that the run will produce a bit-for-bit answer as if the existing run had not stopped. The input data file is determined by the filename set in the restart pointer file (see section 8.2). It is assumed that $CASE has not changed. For a continue run, the only change required in the run script is to set:
RUNTYPE continue
The date will continue from the previous run, since it is read in from the restart file.
