I suspect the example you're looking at was for a procedure which has no
arguments, so in that case it would make sense to pass an empty parameter
list.

I haven't worked with OUT parameters so I don't know if this will work,
but try it and see what happens:

  my_string = ""
  p = [my_string]
  c.callproc('c2_pkg.RS22', p);
  print p
