Assign same value to all observation

[mhabimana]

This is also required to speed up the process of entering data. For the case of rainfall,a whole month or or 90 or 80% of data to be entered in a particular data entry form may be zeros (0),in this case,filling all the cells with zeros using a click would be very quick instead of typing one value at a time.If 80% of data are zeros and 20 % not zeros,you can fill the entire form with zeros and then edit the 20% before you press on the save button.
