[oclug]Really basic Perl help

[Dana Webber]

( /Three/../Three/ )  
this is an array. So $a is getting it's data type changed from string and you 
are seeing some pointer adresses.

try using "marks to make a string like, 
$a = $a . "( /Three/../Three/ ) ";

----------------------------------------
Can somebody take a look at this and explain the results to me?  I'm 
obviously not reading this documentation right...  Please keep in mind I'm no 
programmer...

------ This is my perl script
#!/usr/bin/perl -wT
my $a;
$a="Opening Info \n";
open (DATA, 'data.txt') || die "Couldn't open data : $!";
while (<DATA>) {
$a = $a.( /Three/../Three/ ) ;
}
print "$a \n";
close (DATA);
----- Ends here
