Continue, Break and Return Parallel Behavior
The continue keyword has the same meaning and the same effect inside a parallel loop as inside
a sequential loop: the current run is stopped. The break and return keywords have a different
semantic: break and return only prevent the execution of runs (jobs) that have not begun
(because of .option set_eldo_cl_max_para); all runs that have begun won’t be stopped.
Example: because of parallelism, using a break on the 5th run will not always prevent the 6th
from being executed:
