You are right, tye. Following your suggestion, and by doing this:

my $some_string = "0,-933";


$Data::Dumper::Useqq = 1;         
print Dumper ($some_string) ;

my ($id1,$n1) = split(",",$some_string);
#then do things with $n1 and $n2.

It gives:

$VAR1 = "0,\34-933";

So my questions are:

• How can this \34 comes, in the first place? Can we avoid that?
  My development is always under Linux/Unix platform. And those variable values are read from a file.
• How to remove this \34 character from $VAR?
