in reply to printing 20 characters in a line.

If you don't mind losing $str:

$str=~s/((?:\d+ ){20})/$1\n/g;

print OUT "$str\n";

    or, to avoid modifying $str and be rid of trailing spaces

    my $tmp = $str;
$tmp =~ s/((?:\s*\d+){20})/$1\n/g;
print OUT "$tmp\n";

    [download]

    update: get rid of leading spaces

    my $tmp = $str;
$tmp =~ s/\s*((?:\s*\d+){20})/$1\n/g;
print OUT "$tmp\n";
