Dear all, am trying to print only 20 characters in a line from an array. below is my program. I think its logically right.(i may be wrong). How do i fix this?

#!/usr/bin/perl
use strict;
use warnings;
my $str="30 30 36 33 36 36 36 33 36 34 26 24 21 17 17 23 27 27 31 31 3
+4 33 33 33 36 36 37 38 38 38 38 38 35 40 34 34 34 31 37 36 37 37 40 4
+0 49 40 40 40 40 40 40 40 40 33 30 30 30 30 30 42 45 45 45 45 45 49 4
+2 42";
open (OUT,">format.out");
my @array=split(/ /,$str);
foreach(@array){
    if($_=~/\d+/){
        my $flag=0;
        print OUT "$_ ";
        my $count++;
        my $align=20;
        if ($count/$align==1){print "\n"; $flag=1;}
        if($flag==1){$count=0;}
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
