Hi Thanks for the update. Please send me a notice by email when you ship me a copy. I purchased a copy of 3.0 at the DSSAT course at Olds College in August of 1997 and told I would receive a free update to version 3.5. Thank you for your cooperation, I look forward to working with the new version. Alan Alan Moulin Brandon Research Station Agriculture and Agri-Food Canada P.O.
