in reply to Trouble with Tie::IxHash

I have to read a text file and build a multiple level data structure and display in the same order it was read in.

I found that Tie::IxHash module can make that happen...

Ok, the question is why do you want to use Tie::IxHash. If you want to build an ordered structure why dont you use something like nested arrays of name=>value pairs. 

       $var=[
             'MAIN' => [
                        'ZOP' => 
                                ['Dev', undef, 
                                'Con', undef, 
                                'Test', undef, 
                                'Exit', undef, 
                                'New', undef ],
                        'AP' => 
                                ['Dev', undef, 
                                'Con', undef, 
                                'Test', undef, 
                                'Exit', undef, 
                                'New', undef ], 
                         'Exit' => undef,                             
+  
          
                    ]
             ];

Unless you have some call to address these things by their names you dont need to use a hash at all. You can iterate over such a structure pretty much as as easily as with a HoH, and preserving the order read ceases to be an issue.
