I use Perl only occassionaly and hope that question isn't too trivial.

I got a file 'func_data' with a stored hash structure called FuncAssociateData
(but I don't know how the file was originally created :( ).

The first line of the file looks like:
pst0^D^D^D1234^D^D^D^H^Q^QFuncAssociateData^C^D^@^@^@^D^C{^\^@^@

and I can read the content of the file func_data using:

use Storable;
%FuncAssociateData = %{ retrieve("func_data") };

[download]
and than use the hash without problem.

If I read the file content with

$href = retrieve("func_data");
print "HREF: $href"

[download]
I get
HREF: FuncAssociateData=HASH(0x8206554)

---

My problem starts, when I try to store the hash structure again in a file using:

use Storable;
store(\%FuncAssociateData ,"new_func_data");

[download]

The file format looks similar, but not identical to the original file and the first line in this file looks like:
pst0^D^F^D1234^D^D^D^H^C^D^@^@^@^D^C{^\^@^@

Note that in contrast to the original file the name of the hash variable 'FuncAssociateData' is missing
and if I read the content with

$href = retrieve("new_func_data");
print "HREF: $href"

[download]
it gives
HREF: HASH(0x8206578)

How do I store a hash structure in a file, so that it is stored in the format as in the original file (including the name of the variable containing the hash) ???

e.g.
pst0^D^D^D1234^D^D^D^H^Q^QFuncAssociateData^C^D^@^@^@^D^C{^\^@^@
and NOT just
pst0^D^F^D1234^D^D^D^H^C^D^@^@^@^D^C{^\^@^@

The program using this data file works only with the first format, not with the second one.
Thanks.
