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.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
