in reply to How store a hash table on disk and work with it

I note that you have:

$old_tab{ $cli } = $portingID if $filenum==1; $new_tab{ $cli } = $portingID if $filenum==2;
You'd save memory by packing the old and new $portingID together and using just one hash table. Shouldn't take long to try it and see if it's enough of a saving.

    i have to compare the two has tables after some rules which are in the rest of the program, so thanx but i think no way to store all that stuff in one hash.
