Hi Vipul,

What Fish said, plus:

1. How many files are you talking about? There are limits to the number of files you can open at one time.
2. Please provide a sample file, so we can take a look at the format.
3. What does your subroutine do? Maybe you don't need to have all the files open at once (see above).

Cheers,

Larry

i got that solution but now i have another problem

the function gives a sorted list of hash
but i want two keys current one and next to it how can it be done

Code

foreach my $key (sort {$myhash{$a} cmp $myhash{$b}} keys %myhash) { 
        parsefunction($myhash{$key}); 
}

sort the keys into an array. Then you can use indexing to display the current and next element of the array.
