[Ecls-list] cl_defparameter() question

[Michael O'Connor]

c_string_to_object() works - thanks! However I
couldn't get cl_intern() to work, so this works:

cl_defparameter(c_string_to_object("*test-var*"),
                make_simple_string("test-value"));

But this doesn't:

cl_defparameter(cl_intern(1,
make_simple_string("*test-var*")),
                make_simple_string("test-value"));

I'd be curious to know why that is.

Thanks,

Michael
