I am not sure that J is an efficient language for implementing
these algorithms.

A good J implementation would probably be very educational, but
would probably do a lot of unnecessary work to support potential
but useless forms of generality.

If you use J's package manager and install the arc/zip package, you
can use
   require'arc/zip/zbuffer'
and/or
   require'arc/zip/zfile'

To examine the scripts themselves, replace 'require' with 'open'.
Or, to see some brief examples of the use of these routines use
   open'arc/zip/test'
