          This "zoo" is a broad collection of "animals" that have little to
     do  with one another, but may prove useful for people working in image
     processing and communications.  The software is distributed  with  the
     usual  boring caveat that we don't support the software and you use it
     at your own risk.  To our knowledge all of the material is correct and
     should  work  on  any  VMS 2.3 system.  If there are errors, or if you
     come up with improvements, please contact us.

          Among the items contained are:

     1.  HUFFMAN

              A routine to create Huffman code sequences from a  probabilty
         array.

     2.  HARD

              A program to create quasi-gray scale images on  a  Printronix
         printer.

     3.  Matrix Library

              A set of matrix manipulation routines (May have bugs).

     4.  DR-11c Driver

              An incredibly simple scheme for doing I/O to a cheap DR-11/c.
         This  lets  you  send  and receive 16 bits at a 3 to 4 microsecond
         rate.  This sucker is fantastic and will let  you  do  cheap  real
         time  audio.  Some example programs are included.  Be VERY careful
         concerning the setting of the virtual addresses involved.  We have
         included  several  fortran  programs  that  use  The drio routine.
         these are sine,ramp,and chirp.  To obtain the virtual address used
         in the DRIO routine use SDA on the device.  Use the sysgen CONNECT
         statement to associate a vector and CSR with the device name.  You
         need change mode to kernal privilege to use the address in DRIO.

     5.  QUEUE

              A queuing theory modeler with graphics.

     6.  WEIGHT

              A program to  plot  weight  loss  with  statistics  (Uses  an
         included VT-100 fake-o graphics routine).

     7.  DIGITS

              A program to take data from a Hewlett Packard  plotter.   (HP
         7580 Big Bertha)

     8.  BUBBLE

              A bubble sort routine.

     9.  RPN

              A program submitted  by  DR.   William  Johnson  of  the  Jet
         Propulsion  Laboratory.   This  program will simulate an HP-67 RPN
         calculator on the VAX with a VT-100.


          There should be a COM file for each major program to compile  and
     link.   Each  COM file will also purge back for that program so modify
     this if you want to keep old versions around.

          Good Luck !
