18   Set parameters: The hybrid image computation options are specified with the
19   set command.

22          Specify a mode how to start hybrid computation.
23
24          mode must be one of the following:
25
26          0 : start with only transition function and build transition relation
27          on demand
28
29          1 : start with both transition function and relation (default)
30
31          2 : start with only transition relation. Only this mode can deal with
32          nondeterminism.
