Stack based machines generally need "variable space". This may be quite via a symbol-to-word association a list, a hashmap, or some other system. Here I decide to go for the simplest: extending the register system to a dynamic/infinite number of them. This means, in practice, that we may use a theoretically infinite number of indexed words, hwords and bytes to act as variable space. This means that the onus is on those who are targeting this virtual machine to create their own association system to create syntactic variables: all the machinery is technically installed within the VM, without the veneer that causes extra cruft.
