Michael :
 
The code for missing weather data is indeed -99.  However, before you run
the model, I recommend that you estimate the values of your missing data,
using WeatherMan or other weather data utilities.  The models are not
equipped to handle missing data and will calculate erroneous results.  The
latest versions of the models will stop as soon as they reach a "-99" value
and will prompt you to fix the data.
 
I highly recommend that you upgrade to DSSAT v3.5.
 
Thank you for your interest,
 
Regards,
 
Gerrit
