 How to obtain ATP materials

Everyone who is licensed can use the program free of royalty, but the program is not in the public domain and it is not available via anonymous FTP. The program disks and printed materials (Rule Book, Theory Book, User Manuals) can be ordered from the EEUG by filling out the appropriate Order Form.

Alternatively you also have right asking that materials from any other licenced ATP users, if he or she is willing to share it with you, as it is stated in the license form: ("...The sharing of ATP materials among authorized users is encouraged. If one authorized user has newer or better materials than a second, the first user is encouraged to share with the second...").

While the second option is certainly more simple, please note that the available written ATP materials (Theory Book, Rule Book, MODELS Language Manual, ATPDRAW User Manual) are exceeding 2,000 pages, so only very few of your friends are in a position to be able to make a copy for you free. EEUG offers these materials on a reasonable price, which includes the cost of photocopying, handling and delivery. New users of ATP are advised to orer the first set of ATP materials from a regional user group.


Here you find different order form to order paper form of documentation and other data media perhaps.
Two possibilities you can choose, order from EEUG, distinguishing between being an EEUG member or not, or ordering from CANAM user group.
