+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+			Compilation & misc
+			------------------
+
+
+init	module	( -- )
+		First module, control is passed to on startup. Contains
+		initialization routines. Also it is the last core module.
+		All new modules on top of it comes as result of executing
+		external source files.
+
+head <name>	( -- )	compiles new dictionary entry without specifying
+		new module type.
+		ex: head myentry
+
+: <name>	( -- )	creates new code module
+;		( -- )	ends module (immideate)
+		ex: : hello ." hi there" ;
+
+const <name>	( n -- ) defines new constant.
+		ex: 2147483647 const max
+
+:i <name>	( -- ) same as ":" but this module will be executed
+		immideately even in compile mode.
+		ex: :i ( 41 scan ;
+
+create <name>	( -- ) same as "head" , but specify module type as data.
+		ex: create LotoResults 5 , 13 , 52 , 12 , 11 , 3 ,
+
+allot		( n -- ) allocate n bytes in dictionary.
+		ex: create MyArray 100 allot
+
+" <string>"	( -- ) compile string and its size into core.
+		ex: create Mystring " This is it's contects"
+
+str <name> <string>" ( -- ) just shorter way for defining strings.
+		ex: str Mystring This is it's contenc"
+
+var <name>	( -- ) define new 32 bit variable.
+		ex: var result
+
+' <module>	( -- n ) return memory address of given entry.
+		ex: ' init
+
+forget <name>	( -- ) erases from RAM given entry and all entries what was
+		defined after it.
+		ex: forget myprog
+
+[		( -- )	set interpret mode (immideate)
+]		( n -- ) set compile mode and compile top stack element
+		in as literal. Together [ .... ] cobination provides good
+		way to compute some values only once, at compile time,
+		rather than every time while program is running.
+		ex: : calculate - [ 4 MyConst1 + MyConst2 * ] ;
+
+defer <name>	( -- ) creates new module, with jump instruction.
+		Later address where to jump can be modified by "is" command.
+		This provides method of foward referencing. So you can use
+		modules what not jet exist.
+is		( address1 address2 -- ) address1 - where to jump, address2 -
+		address of module created by defer command.
+		ex:	defer dispver
+			: run dispver ." running ..." ;
+			       ... whatever ...
+			: (dispver ." Version 9.99 " ;
+			' (dispver ' dispver is
+
+		Now if I type "run" on the screen appears:
+			Version 9.99 running ...
+
+asc <char>	( -- ) reads char ascii code and treats it as literal.
+		(immideate)
+		ex: : BreakLine 30 do asc - emit loop ;
+				 same as:
+		    : BreakLine 30 do	 45 emit loop ;
+
+dyninc		( handle -- ) execute code in dynamic memory handle.
+		automatically deallocates it when done.
+
+include 	( filenumber -- ) execute code in specified file.
+
+words		( -- ) display existing blocks in core.
+
+bye		( -- ) exit from Fifth
+
+fkey		( -- c )
+		Read one byte from input stream.
+
+sadd		( c addr -- )
+		Add one byte "c" to string located at "addr" and updates
+		string length.
+
+scan		( c -- )
+		Read input stream and store it to  pad	 until it finds  c  .
+		It ignores all "c" bytes until it finds any non "c" byte.
+		in other words:
+				c  is:	"
+			 input stream:	""""This is test !"aoeu idh
+			       result:	This is test !
+
+		Is useful for breaking text lines into words.
+
+skey		( -- c )
+		So called safe "fkey". Reads data from input stream
+		but converts characters with ASCII codes: 9 13 10
+		to spaces.
+
+str=str?	( adr1 adr2 -- result )
+		Compares string at "adr1" with string at "adr2", returns
+		true flag if they are equal or false if they are not.
+		true = -1
+		false = 0
+
+find		( -- addr )
+		Searches whole dictionary for word in "pad". If found,
+		returns it address, if not, returns 0.
+
+execute 	( -- )
+		Execute word located in "pad". Depending on "mode".
+
+dta		( addr -- DataAddr )
+		Calculates address of dictionary entry data area, from
+		entry point.
+
+2num		( -- num result )
+		Attempt to convert string located in "pad" into numeric
+		value. If succeed returns number and true as result.
+		If not, returns whatever and false as result.
+
+dadd		( addr length -- )
+		Add to dictionary data located at "addr", with specified
+		length.
+
+lit		( n -- )
+		Act with number depending on "mode". When interpreting,
+		leaves it in stack.
+
+
+incmod		( addr -- )
+		Add to dictionary data located at "addr"+1 , length is taken
+		from "addr".
+
+here		( -- n )
+		return "h" contents.
+
+mode	var	8 bit
+		Holds input stream parser operation mode.
+		0 = interpreting
+		1 = compiling
+
+pad	var	128 bytes
+		Holds temprorary strings.
+
+h	var	32 bit
+		Pointer to free byte in memory, always at the end of the
+		dictionary. Each time when something is stored
+		by "c," command, pointer is incareased.
+
+lp	var	32 bit
+		Pointer to last dictionary word. Each time when new word is
+		compiled or erased by "forget", this pointer is updated.
+
+modulechk	( Dstr<filename> -- ) check if module is loaded, if not
+		immideately load it.
+
+ne		( entrydata entrytype -- ) Compile new dictionary entry.
+		It's name must be in "pad".

+                        ------------------------
+
+Fifth supports both static and dynamic strings.
+Static strings must have predefined space reserved,
+and string mustn't exceed this length. They manipulation is
+faster. But they use more memory. Static string memory address is used
+to refer to the string.
+
+Dynamic strings can have at any time length form 0 to 0FFh,
+They take up only memory they currently need. They are held
+in dynamic memory blocks, so dynamic block handle is used to refer
+to this string.
+
+Both types of strings are stored in the way, where first (0th)
+byte holds current string length, following bytes are string itself.
+
+Dynamic:
+
+Dstral ( -- handle )

+
+c+lDstr ( chr handle -- )
+                Add one byte to left side (beginning) of the string.
+
+Dstr. ( handle -- )

+
+Dstrsure ( size Dstr -- )
+                Makes sure that at least rquested
+                "size" (amount of characters) is allocated for given
+                dynamic string.
+
+Dstr2str ( handle address -- )

+Dstr ( data" name -- )
+                Creates new dynamic string and moves specified data into it.
+                Then creates new constant with given "name" holding created
+                dynamic string handle.

+    <h2>Emulator & virtual CPU</h2>
+
+
+
+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 and
+resident drivers services in real mode. So I don't need to deal with
+hardware too mutch. It also allows me to use all free XMS for flat
+code & data storage.
+
+Current emulator emulates 1 CPU. It has 2 stacks,
+~50 instructions, and 4GB flat address space (theoretically).
+I'm not sure that DOS 6.22 that I currently prefer can handle more than
+64 MB of RAM. While I tried to keep instructionset simple,
+I was forced to put in lot of complex instructions to make it's performance
+acceptable on emulator. On actual silicon ~20 instructions is enaugh
+(I think).
+
+Maybe one day similar system will run directly on custom silicon chip :)
+
+
+CPU has following registers:
+
+IP	- instruction pointer
+DSP	- data stack pointer
+RSP	- return stack pointer
+
+Virtual CPU, commands (most of them are avaiable as ordinary commands in
+programming lanquage):

+
+<h2>Introdution</h2>
+
+Fifth is programming lanquage & operating system, running on
+<a href="emulator.html">virtual CPU</a>, with custom instructionset. It is mutch like
+Charles Chunk Moore's Forth, it also uses stack architecture,
+and many commands are similar. Basically I got famailiar with
+concepts of Forth, and being inspired created my own system.
+<p />
+Note:
+<i>
+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 <a
+                href="http://svjatoslav.eu/static/gitbrowse/sixth/doc/index.html">Sixth</a>.
+</i>

+<br>  <a href="modules/index.html">Additional commands, realized as loadable modules</a>
+<br>  <a href="5TH_ET.txt">Example Fifth source file - text editor </a>
+
+
+    <h2>Installation</h2>
+
+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 ).
+Read more about <a href="files.txt">distribution directory layout</a>.
+
+
+
+    <h2>Software/Hardware/Human requirements</h2>
+
+
+Software:	MS-DOS 6.22, with HIMEM.SYS loaded.
+		Mouse driver if you have a mouse.
+		Does work only when CPU is in real mode.
+		To recompile ASM sources I used FASM (Flat Assembler).
+		I ran QBasic utilites on QB 4.5 .
+		VESA support by BIOS, or external driver (UNIVBE).
+
+Hardware:	Minimum CPU 386.
+		Recommended CPU Pentium 133.
+		64 KB free RAM below 640KB,
+		2 MB of free XMS.
+		VESA compatible video card.
+
+Human:		Beginner level Forth knowledge is recommended.
+		Enthusiasm.
+
+
+
+    <h2>Numbers representation</h2>
+
+<img src="numbers.png">
+
+Fifth uses hexdecimal number representation as primary.
+Numbers shape is formed by dividing a square into four parts.
+And manipulating their color (black or white).
+
+
+
+    <h2>Disk file map, and it's data structures</h2>
+
+
+Core & highlevel boot code is stored outside of the filesystem to allow
+easy access to it, at early booting time, when filesystem is not yet
+initialized.
+
+			disk allocation:
+
+offset	length	description
+
+0	~4 Kb	Fifth core
+4  Kb	~32Kb	highlevel boot code
+37 Kb	~65Kb	FAT
+101Kb	~16MB	filesystem data area
+
+			FAT entry format:
+
+-2	last sector
+-1	empty sector
+0 --  .. pointer to next block
+
+			file entry format
+
+offset	length	description
+
+0	4	extension
+4	16	name
+20	4	entry point
+24	4	size
+28	4	last modification time
+
+
+
+    <h2>Core architecture</h2>
+
+
+Fifth core is simply some amount of already compiled into machine code
+and linked together modules (entries in other words). In compilation
+process modules is compiled one by one and simply stored on top of
+already existing and growing core. Separately from core is kept
+dictionary, this is special list that contain names of compiled modules,
+variables etc. and they locations in core. Constants use dictionary space
+only. Random word can be removed from dictionary at any time. Currently
+dictionary can contain at most 1000 entries.
+
+
+			dictionary entry format
+
+offset	length	description
+
+0	4	 0 &lt; previous entry
+		 0 = last
+		-1 = empty
+4	15	module name string
+19	1	entry type
+20	4	entry data
+
+Core headers as linked list of module names make up something like dictionary.
+When some entry address is needed compiler can quickly run through headers
+backwards and find needed entry.
+
+			Possible module types
+
+type	description	"execute" action
+
+0	data		compile "num" instruction
+			with address to module
+1	submodule	compile "call" instruction
+			with address to module
+2	imm. submodule	immideately call to module
+
+
+		Memory map: (average)
+
+<loc>	<size>	<desc>
+0	~4096	core
+1500000 ~32000	highlevel Fifth boot code
+200000h 	core startup messages area
+5200000 	end of dynamic memory space
+
+
+
+    <h2>Fifth source format</h2>
+
+
+Fifth uses a different character table and codes than ASCII.
+I call it FSCII (Fifth Standard Code for Information Interchange)
+for example space character is not 32 but 255 instead.
+I plan to use mainly HEX numbers, and create new characters
+to represent numeric values. So typical nemric characters "0123..."
+is treated like ordinary letters.
+
+	FSCII:
+
+DEC	HEX	function
+
+0 - 15	0 - F	HEX numbers
+252	FC	backspace
+253	FD	tabulator (TAB)
+254	FE	carriage return (CR)
+255	FF	space
+
+else		ordinary characters, like in ASCII.
