      Hi, there !

      In the system's web page,


      there are new packages for zero, the 2.0.5 version, this time for windows and
      for linux. However, the linux executables are dynamic ones. This means they
      are tied to libstdc++6-3.4.3.

      What's Zero ?

      Zero is a simple, tiny object-oriented, prototype-based programming system
      which has been designed for education. Right now, the virtual machine, the
      assembler and the macroassembler are available.


      The install of Zero is very simple, and it doesn't affect the OS in which it
      lies: it is merely a matter of uncompressing the zip file in any new folder.
      Then, you should browse and follow the instructions in "readme.txt".

      In order to uninstall, you do only need to erase the folder.

      Web changes

      The web page has been extended with the following sections: How to
      contribute, Standard's Library capabilities manual, and Examples. In the
      first web page it is explained that you can specially contribute to Zero if
      you are a lecturer and want to use Zero in any subject related to object
      technology. Other ways of helping specially include creating programs with
      Zero and eventually find bugs, which will make the virtual machine even more
      stable. Those programs sent to the contact address will be published in the
      section of Examples. Last but not least, The Standard's Library capabilities
      manual explore the basic capabilities of the VM and explains them with tiny

      Aditions to Zero

      Visual Zero
      The windows zip file includes Visual Zero, as usual since version 2.0.4: it
      is graphic user application able to show the execution of a Zero program step
      by step, like a debugger, as well as exploring the objects present in the
      system. It is a good tool for demonstrating system's work in the classroom,
      for example.

      Structural reflection

      Structural reflection is now available and complete, for attributes and

      The compiler has been inserted into the virtual machine. Now it is possible
      to create and modify new methods in execution time. For this, you only need
      to use the inherited methods addMethod() and compilteToMethod(), which are
      explained in the web page in detail.

      Kind regards,
