You have to give a name to the interface

  interface Foo {

You can't call your struct "object", since "Object" is a keyword.
Let's call it my_struct. (Not my_object, since that leads to confusion
with interfaces.)

struct my_struct {

This line doesn't gain you anything, but changing the names, it's OK:

  typedef my_struct my_struct_type;

>      long object_list(in long index, in object_type list[50]);

You can't have anonymous arrays in operation parameters. You should do

  typedef my_struct my_struct_list[50];

  long object_list(in long index, in my_struct_list list);


Depending of what you are trying to do, it's quite possible that you
would be better off using a sequence rather than an array, since
sequences can vary in length.

Cheers,
