Dear<br>Kishore<br>It is given in the use guide. The command is "addc" to add a constant value to all fields. But for a particular region you have to make a new file extracting that region. then use "addc" add that constant you want. The syntax is:<br>
<br><b>cdo addc ,100 ifile ofile</b> to add 100 to all values of ifile and write them in ofile.<br><br>Regards<br>'S Maity'<br><br clear="all"><div><div><i><font style="background-color:rgb(255,153,0)"><span style="background-color:rgb(255,255,255)"><font face="comic sans ms,sans-serif"><b><font size="4">*******************************************************<br>
