Hello ELISHEVA,

I'm not sure I understand what you are trying to do. Your description implies to me that you are trying to save a file handle for later use, but your trying to use I/O to a scalar in memory. 

  my ($s1, $s2) = ('','');
     . . .
  open(my $fh1, '>', \$s1) or die "Can't open fh1";

You are opening a defined but empty string variable by passing a reference to the string. This maybe a new feature of Perl that I'm not aware of, but usually you open a file on an external media.

More clarification will be needed to give a better answer, but if you want to save the file handle ( $fh1 ) for later use, you could use a hash or array, which will preserve the definitions of $fh1.

Regards...Ed
