You might try the FEATURES program from the XYLEM package, which was
described in

      Fristensky, B. (1993) Feature expressions: creating and manipulating 
      sequence datasets. Nucl. Acids Res. 21:5997-6003.

FEATURES is a program that can read GenBank Features Tables and 
extract the corresponding sequences, Feature expressions, and
annotation lines. FEATURES is a Unix program, which can be run from
the command line, as a text-based interactive program, or from a GDE menu.

To see an example of how FEATURES works, and to retrieve the XYLEM package,

XYLEM can also be downloaded from directory 'psgendb' at ftp.cc.umanitoba.ca.
