Hi,
in the following block of code (taken from a program that I wrote), I get the error:
Use of uninitialized value $" in join or string at my_implementation.p
+l line 215.

Can you tell me what I must add/correct? 
        open OUT_A, ">$a_file";
        for my $d ( 0 .. $#table_A ) 
        {
            my $row1 = "@{$table_A[$d]}";
            $row1 =~s/\s/\t/g;
            print "$row1\n";
        }
        close OUT_A ;

.
The error line is: my $row1 = "@{$table_A[$d]}";
