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

+Fifth is programming lanquage & operating system, running on [[id:9b251eb9-aff6-4025-94bf-25e89e26d54a][virtual
+machine]], with custom instruction set. It is much like Charles Chunk
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 ).

After downloading and unpacking the ZIP file you shoud get directory
tree similar to this:
| 200000h | | core startup messages area |
| 5200000 | | end of dynamic memory space |

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
