Perl arrays and loop through array
Hi All

I need to get <STDIN> from a user. the <STDIN> is a range of number delimited by "," (comma) and can be with range delimited by "-".

Example: 1,2,3,4-9,12,15,34-36,70

Now I need to get this from the user and go on each number and "Do something"... but when trying to do this as above the loop use the array element as string.

Code:
my $str = "1, 2 ,3, 4,6 -10,11 - 15,16, 17";

$str =~ s/\s+//g;
$str =~ s/-/\.\./g;
my @arr = split /,/, $str;
for (@arr){
    my $i = $_;
    print "==>>> $i\n";
}

The result of this is:
Code:
==>>> 1 ==>>> 2 ==>>> 3 ==>>> 4 ==>>> 6..10 ==>>> 11..15 ==>>> 16 ==>>> 17

and not:
Code:
==>>> 1 ==>>> 2 ==>>> 3 ==>>> 4 ==>>> 6 ==>>> 7 ==>>> 8 ==>>> 9 ==>>> 10 ==>>> 11 ==>>> 12 ==>>> 13 ==>>> 14 ==>>> 15 ==>>> 16 ==>>> 17

as wanted...

Any suggestions? Thank you all.
