Depending on how much use and how much "batch" querying you will be doing,
you can fairly easily set up a GFF relational database and load the
chromosome data into it. You can then do "local" slice-like queries. You
can also load features if you have them in GFF format. See Bio::DB::GFF for
some examples of what you can do.
