This document specifies how the CommonTalk virtual machine works.

The main execution engine is the ctState object, it contains the following:

• The "root" object, the only object in the system which does not have a parent object.
• The "ct" object, this object contains the basic objects needed for operation of the virtual machine:
• Object, the base object.
• Code, an object containing a list of opcodes to be executed by the virtual machine.
• NativeFunction, an object containing a reference to a native (as in C) function.
• Stack, this is used to keep track of the execution as well as the "current" object, for instance, when a function is to be called, the "this" object, the name of the function and the function parameter.
