Fortran90 Array read blank values as null

I'm reading data fram a external text file (30 Rows, 7 Columns), each row is seperated with a ",". I have missing values represented as ",,". When i read data into a two dimensional array the missing value is replaced with 0.00, but i have a 0.00 value in the data too. When i am computing average the count (number of items (n)) showd be count - (number of missing values). How can i pick the missing values dynamically.

Thanks Sri

You do not seem to have negative values in your data, how about doing some pre-processing before passing the data to fortran, where you replace the ',,' with a negative value, for example with

sed 's/,,/,-1,/g'

Then you can easily identify these invalid data in your Fortran program and treat it accordingly.
