1. But if I don't call ruby_run(), how does it interpret?
2. When I am running a script, say with the line
        puts 'hello'
   from within my c-program, no 'hello' pops up on my term.
3. What I meaned was like:

     c program:
        VALUE ruby_func()
        {
             /* ... */
        }
        
        void blah_blah()
        {
            ruby_init();
            ruby_script("foo.rb");
            ruby_run();
        }

     foo.rb:
        # ...
        ruby_func        # call ruby_func that appeared in the
        # ...            # same app as the caller of ruby_run()

   Is this kind of operation possible?
