The correct method for taking command line parameters into a Perl script is to use the @ARGV array. Your example might look like 
    open(FILE,"<", $ARGV[0]) or die "Open failed for $ARGV[0]: $!";   
+        
    my @lines=<FILE>;

which the user would invoke as 
$ perl script.pl Working_On.csv

Note as well that I've added a test to see if the file open succeeded, and added a diagnostic in case it didn't. See Simple Opens in perlopentut.
