What language is this?

It looks like awk, but awk doesn't have "multidimensional arrays" as such... Just a big list of indexes and elements. When you give more than one index, it actually crams them into a string like INDEX1 SUBSEP INDEX2 SUBSEP INDEX3.

So your method would still count every individual element of a multidimensional awk array. But they would have to all be filled. Any unset elements would not be counted.

Thanks Corona for reply

I tried like this to remove blank fields
Worked fine

for(i=1;i<=10;i++)
        if(A[1,i,1]=="")
            print "Blank"
        else
            {
            f++
            for(m=1;m<=5;m++)
            F[f,m]=A[1,i,1] 
            }
