Dear Dssat\'s users, I apologize for re-sending this message. I can not know if its go through the first time I am running DSSAT3.5 on a PC with Windows98 and I am getting some errors messages when I try to run some crops (peanut) or Seasonal experiments. I got the following: C:\\Marta|DSSAT35\\Peanut\\ExpLst.DBF (Dos ERROR 5) and ERROR DBCMD/2001 workarea not in use ORDLISTADD. For the seasonal, C:\\marta\\dssat35\\seasonal>echo off swapping to C:\\marta\\dssat35\\ALAFBMAD. Then the program stops, and if yoy look for the problem it says General Protection exception FFF.FFF. Is there any incompatibilities with windows98? What is amazing is that I can run maize or soybean, etc, although it is not possible to run peanut or seasonal. I did not try all the other crops. I will appreciate very much if someone could provide any clues. Sincerely, Marta Vinocur Ing.Agr. M.Sc.
