Hi to everyone around the world. I have installed Win.98 in my computer (Cyrix 266) and DSSAT v.3 as well. When I want to use analysis program under Seasonal and Sequence I will see these messages "C:\DSSAT3\seasonal>echo off " and "Swapping to: C:\DSSAT3\ and 8 characters such as: BFAOBJFP or BFBAAFEF or BFCNBHBP or ...under previous line" and then it freezes. I configured program for protected conventional memory and editor to C: windows/command/edit.com. but it doesn't work. Also, it doesn't work in DOS mode, that loaded HIMEM+EMM386 as readme.txt Any suggestions to disable the swapping and running the analysis section?
