[gradsusr] Change of month

[James T. Potemra]

Miquel,

We'd need to see you control files, but I suspect the TDEF line is 
causing problems.  I believe this gets set with your first open file.  
For example, if you open a file and "set t 1", time will get set to some 
date as defined in that control file.  If the subsequent files don't 
have this date defined you'll get the grid coordinate error.  You could 
issue a "set dfile" command to re-set the coordinates.
