Now i am counting the values in the third column i.e how many up words how many down words and how many NA. For that i wrote the following program:

@values = values(%hash);

for $element (@values){
 if ($element =~ /up/){
    $sumA++; 
}if(($element =~ /down/)){
    $sumB++
}if(($element =~ /NA/)){
    $sumC++
}
}
print "Number of up is: $sumA\n";
print "Number of down is: $sumB\n";
print "Number of NA is: $sumC\n";

it is doing a great job but when i add a same row in the last of the file it doesn't count its up, down or NA word. why is that?

In reply to Re^4: Split a column by shabird
