hellow ....

your code needs some modifications ..

in your code if ($count/$align==1){print "\n"; $flag=1;}
it will print new line on terminal not in file.so change it with print OUT "\n";

if($flag==1){$count=0;}

after this line the value of $flag variable is always 1 so change it .....

One more thing define $flag & $count outside the for loop.

no need of $align. you can direct compare the $count == 20 .
