What martin suggests is correct. You should declare all entries, regardless of
whether you will use them or not.
In your cc file, move all the prm.declare_entry functions before:
prm.declare_entry ("System Type","Error", Patterns::Anything(),"The type of
system being solved: eg. foo, bar, etc.");
prm.declare_entry ("prm foo","false", Patterns::Bool(),"Some Boolean: true
or false");
prm.declare_entry ("prm bar","false", Patterns::Bool(),"Some other Boolean:
true or false");
prm.read_input(prm_file_name);
system_type = prm.get("System Type");
if (system_type == "foo")
etc. etc.
Something similar is done in step-34, where the parameter handler is declared
for both 2 and 3d, and then one decides from the prm file itself if it wants to
run the 2d or the 3d code.
