Actually what you really need is a hash not an array ...

There are a couple of very strange things with your questions and code ..
firstly you dont need to put the $_ in the foreach line ... if you dont put
anything there then it will pull the value into $_ on each iteration
secondly your question that $_ was an array is clearly wrong ... $_ can only
something like this

# Nothing special .. just opening the file handles

open(ONE,one.dat) or die $!,\n;
open(TWO,two.dat) or die $!,\n;

#
# sending the file handle into a reference as a glob
# you could also do this $fh =
The first lien makes sure that subsequently $b will not be defined anymore.
THis is necessary whenyou are somehow using the variable $b in subsequent
lines but wanna make sure that there is no previous values to corrupt it.
i have seen it used in a lopp where $b is a global variable for example
my $string = 'pgrap.C4A2S1R.1.gif';
my @s = ($string =~ /(?:\.)*(\w+)(?:\.)*/g);
the arraytores the elements

I assume you have write privellages for the directory (or else you would not

You dont really need to use a hash ... just read in the files and then push

Depending on the context of the string you want to parse there is more than

$string = substr($string,-9,9);
