Hi
  Forth is also one of the few languages that can readily be created 
from scratch on most computer platforms. Most other languages, you are 
tied to some vendor to supply a compiler for you.
  Once the core is running, the levels of high level constructs can be 
easily replicated on some future machine using the original code. This 
does assume that they will still be using basically a Von Neumann type 
design or a Harvard like machine, such as the x86 has become.
