  Current implementation does not support object oriented
  programming. While working on Fifth I got lots of cool new ideas that
  require reimplementation of everything.
  
  Currently I try to implement those new ideas in the project called

  Moore's Forth, it also uses stack architecture, and many commands are
  similar. Basically I got familiar with concepts of Forth, and being
  inspired created my own system.

  * Installation
  Just unpack all files, witout altering original directory structure,
 -somewhere in your hard disk. For example:
 -: C:\MISC\FIFTH\....
 -To run fifth you need minimally just 2 files.  emulator itself (
 -EMULATOR.EXE or EMULATOR.COM ), and virtual disk file ( DISK.RAW ).

  Using CPU emulator slows it down but I shouldn't now think too mutch
  about, and waste my time on batteling with problems whitch results on
  complex design of PC hardware. Also it allows me to use existing DOS
