Cat (Computational Analysis Tools)
Version 2.0

Date:
  14 December, 2000

Author:
  Alan Freed

Platform:
  Cat was written for Native Oberon (System 3) and requires version 2.3.7 or later.

Objective: 
  A library of base numeric types from which most common application types used in 
  computational analyses can be rapidly assembled using System 3 as the underlying 
  framework.  This library is to take full advantage of the enhancements to the 
  Oberon programming language that are present in the Native Oberon compiler to 
  help improve user productivity.

Backward Compatibility:
  Cat 2.0 is not backward compatible with prior Cat 1.x versions.  The reason for 
  this is that Cat 2.0 takes full advantage of the enhancements in the Native 
  compiler; whereas, prior versions did not.  For this reason, prior versions 
  are no longer supported (at whatever level I'm capable of supporting:-).

Base Types:
  Cat 2.0 provides base types for integer, rational, real and complex numbers, 
  their vectors, and their matrices.  All arithmatic operations are overloaded.  
  There is only one integer type, one real type, etc.  The bit size of each 
  number type is hidden, providing a stable interface that is easily extended 
  when 64-bit, 128-bit and higher-bit CPU's become available without influencing 
  existing code that is built upon Cat.

  Also provided is a base type for persistent Cat objects (i.e., Cat.Object) that 
  you can extend to create your own computational data structures, whatever 
  they may be.  Several generic data structures are provided: stacks and queues, 
  which are not persistent, and lists and trees, which are persistent.  Cat and 
  Gadget objects are distinct, i.e., Cat.Object does not extend Gadgets.Object.
  
  An address book is included as an example of how Cat and Gadget objects 
  can coexist.  Open it by executing:  Desktops.OpenDoc AddressBook.Panel

Installation:
  Compress.ExtractAll Cat20.Arc ~
  Compress.ExtractAll Addresses.Arc ~  (It is bound into Cat20.Arc.)

Future Releases:
  Removed from the prior versions of Cat are higher-level modules for doing 
  things like calculus, optimization, solving differential equations, and the like. 
  These will be re-released sometime in the future under the prefix Ex.  Cat is 
  intended to be a minimal library of modules necessary for doing computational 
  analysis.  Ex will contain extended features that many users will not need.
