Dear Dr. Jones:

This is to accept IBM's kind invitation to take part in the IFIP Working
Conference 'The Role of Abstract Models in Information Processing' which
is to take place in Vienna.

The title of my speech will be 'Changing Programs without Reading Them--
Towards Yet Higher Level Programing Languages'.
