1. H would like permission
(which has already been granted by publisher) to
use HUC 6 program — commercial software.
2. Is the listing available on floppy disk?
3. Thank you for a very interesting and useful book.
4. He left his fax # and telephone #. He wasn't sure of the country code.
He would appreciate hearing from you via fax.
