The Strips software is available via anonymous ftp at sauquoit.gsfc.nasa.gov While there is no promise of formal software support, periodic updates will be placed in the ftp directory. Bug reports, comments, suggestions, etc. should be sent to idm-users@dunloggin.gsfc.nasa.gov If there is enough interest in starting a bulletin board, send email to this account. Finally, as is the tradition with shareware, we hope that various developers will contribute to this code over time. We promise to make every new release available at this location. In fact, the next planned release will follow the Fikes paper and is planned for release in a few months. HAPPY PLANNING, Nick Short Code 930.4 NASA/GSFC Greenbelt, MD 20771 (301) 286-6604
