Novell has a program called the Professional Developer's Program
(PDP), which gives NetWare-aware application developers streamlined
access to NetWare products, development tools, and support services. 
Through the program you can get discounts on additional copies of
NetWare OS and Communications products with a one-year renewable
license.

Joining the PDP is the only way to get access to some Novell Software
Development Kits (SDKs).  There is a private forum on CompuServe
for PDP members.  In addition, through the PDP, Novell offers some
marketing support.

This program is available to professional developers of NetWare-Aware
software products.  Contact Novell's PDP in the U.S. and Canada at 

        1-800-NETWARE

International developers should contact their local Novell office
regarding the PDP features in their area.  Services vary from country
to country.

Note from Glenn:

        Clipper developers will not likely need or be able to use
        most of the PDP's development kits.  But if you build 
        NetWare-Aware applications, you should be testing them on 
        NetWare networks.  The PDP currently offers a cost-effective
        way to set up a test environment and keep it current.
