No i dint get any message

my code of the called file is

$_="My Page";
$datalen=$ENV{'Content_Length'};
read(STDIN,$q,$datalen);
@data=split(/&/,$q);
$len=@data;
for($i=0; $i<$len; $i++)
{
$data=@data$i;
$data=~ s/\s|t=|RUN//g;
@data$i=$data;
}
$a1=(@data[0]);

$a1 gets the file path,like C:Projecct\jeisika\mol.pdb
which i plan to open and analyze, whereas, when made to run on server this file path comes to perl file as "mol.pdb" only!
This is the first problem

and the second is that i dont know whether i have to upload this file to server before running. Cannot it be done by browsing the file path and then POST it to the second pearl file where this file should be opened and analysed??

Why do you need the entire path to the file?  On the remote machine you have a different file system, where that path will most likely not be valid anyway...  Most browsers (except some versions of IE) are aware of this, and simply strip the directory component of the local path — in part because it may unnecessarily disclose private details of your local machine.

If you want to analyse the contents of the file, there is no way around uploading those contents to the server, as the server cannot access C:Projecct\jeisika\mol.pdb on your local filesystem.  Read what the Anonymous Monk pointed to on how to upload files via CGI.

$datalen=$ENV{'Content_Length'};
read(STDIN,$q,$datalen);
@data=split(/&/,$q);

I guess you would save yourself a lot of pain if you used CGI instead, which parses CGI parameters and handles uploading of files for you.

thnx Carion....
I suppose Im still not clear about my problem: Here's know the details
---------------------
I want to read a file in PDB format from client by this code by using "POST"
index.pl goes like this and calls results.pl


<form action=results.pl method=post>
<input name=t type=file />
<input type=submit name=t
value=Run />

Now the file whose path is passed to results.pl by the form above, is to be opened and analysed on server.
What to include in index.pl to open the file from client on the server?
