I'm trying to run a while loop, after reading from a file. When I use variable, the while loop is not working. However when using absolute path, it is working fine. Please let me know of a way in which I can use the variable. 
#    my $filename='$mydir\file_detail.txt';
#    open (FILE, '$filename');
    open (FILE, 'D:\SiebelAdmin\CSS\file_detail.txt');
    while (<FILE>)
        {}
