As seen on section 1.3, AriNET is based on PLT Scheme. This means most of the Scheme commands work with AriNET. Moreover in order to model complex arithmetical networks you will have to use Scheme commands.
Rewriting a exhaustive list of Scheme commands would be non-sense. This is why you will find in Appendix D a copy of the ``Revised Report on the Algorithmic Language Scheme'', a really good paper containing every single Scheme command available.15.
For further information on PLT Scheme, consult Appendix A.
