  threaded code
       
           A technique for implementing virtual machine
          interpreters, introduced by J.R. Bell in 1973, where each
          op-code in the virtual machine instruction set is the
          address of some (lower level) code to perform the required
          operation.  This kind of virtual machine can be implemented
          efficiently in machine code on most processors by simply
          performing an indirect jump to the address which is the next
          instruction.
       
          Many Forth implementations use threaded code and nowadays
          some use the term "threading" for almost any technique used to
          implement Forth's virtual machine.
