+                                  EXE2COM 1.04
+                         By Chris Dunford/Cove Software
+
+        | indicates information changed/added in recent versions.
+
+        Purpose
+        -------
+        EXE2COM is a one-for-one replacement for the EXE2BIN program
+        that was formerly distributed with DOS.  Beginning with DOS 3.3,
+        EXE2BIN has been moved to the disk that comes with the DOS
+        Technical Reference and thus is not available without extra
+        cost.
+
+
+        Usage
+        -----
+        Usage is identical to DOS's EXE2BIN except that the output file
+        extension defaults to COM rather than BIN, and there is an
+        optional switch that displays EXE file information rather than
+        converting the file to COM.
+
+        Complete usage is:
+
+            EXE2COM [/I] [d:][path]file[ext] [d:][path][file][ext]
+
+        The drive and path of the first file default to the current
+        drive and path, if not specified.  The extension of the first
+        file defaults to EXE, if not specified.
+
+        If the second file is completely unspecified, it defaults to the
+        same drive, path, and filename as the first, except that the
+        extension will be COM.
+
+        If the second file is specified but without an extension, COM
+        will be assumed (this is different from EXE2BIN).
+
+      | If /I is specified, information about the EXE file is displayed
+      | and no conversion is performed.  The output file name, if
+      | specified, is ignored.
+
+        The simplest (and usual) usage is simply:
+
+            EXE2COM file
+
+        which will take the named EXE file in the current directory and
+        convert it to a COM file in the same directory.
+
+
+        Operation
+        ---------
+        EXE2COM runs the same way as EXE2BIN, with the following
+        exceptions:
+
+            1. The binary fixup option of EXE2BIN (IP=0, segment fixups
+            required) is not supported.
+
+            2. The EXE file checksum is not verified.
+
+            3. Error messages are more useful, and a warning is provided
+            if a COM file is created with an initial IP other than 100H.
+
+            4. The default output file extension is COM rather than BIN.
+
+
+      | Information display
+      | -------------------
+      | If you use the /I switch, EXE2COM just displays information
+      | about the EXE file and does not attempt to convert it to COM
+      | (therefore, the EXE file need not be a convertible file).  Here
+      | is a typical display, resulting from running EXE2COM on itself
+      | (version 1.04) with the /I switch:
+      |
+      |   exe2com.exe                   (hex)      (dec)
+      |     EXE file size                396B      14699
+      |     EXE header size (para)         20         32
+      |     Program image size (bytes)   376B      14187
+      |     Minimum load size (bytes)    8CDB      36059
+      |     Min allocation (para)         557       1367
+      |     Max allocation (para)        FFFF      65535
+      |   * Initial CS:IP           0000:072C
+      |   * Initial SS:SP           084D:0800       2048 (stack size)
+      |   * Relocation count                4          4
+      |     Relo table start             001E         30
+      |     EXE file checksum            411D      16669
+      |     Overlay number                  0          0
+      |   * = this item prevents conversion to BIN/COM
+      |
+      | The fields that may need some explanation:
+      |
+      | Program image size:  this is the size of the program itself
+      | (i.e., the size of the EXE file less the size of the header
+      | information).  This much memory is required to load a copy of
+      | the program's code and pre-allocated data.
+      |
+      | Minimum load size: at least this much free memory is required in
+      | order to run the program.
+      |
+      | Min/max allocation: the minimum/maximum number of 16-byte
+      | paragraphs that will be needed above the end of the program
+      | image when it is loaded.  Minimum load size is the sum of the
+      | program image size and the minimum allocation.
+      |
+      | If an item is starred (*), this prevents the EXE file from being
+      | converted to a COM file.
+
+
+        Error Messages
+        --------------
+        These are EXE2COM's error messages.  If one of these is seen,
+        the EXE file will not be converted and the errorlevel returned
+        by EXE2COM will be 1.
+
+        ERROR READING EXE HEADER
+            EXE2COM was unable to read the EXE file header from disk.
+
+        ERROR WRITING OUTPUT FILE
+            EXE2COM was unable to write the converted file to disk.
+
+        INVALID EXE FILE SIGNATURE
+            The first two bytes of an EXE file should be ASCII 'M' and
+            'Z'.  This was not the case, and it's probably not an EXE
+            file.
+
+        EXE HAS RELOCATABLE ITEMS
+            In order to be converted to a COM file, an EXE file cannot
+            have any direct references to segments.  For example, the
+            assembler instruction "mov ax,code" (where CODE is a segment
+            name) is a segment reference.  One or more segment
+            references were found in the EXE file.
+
+        EXE HAS STACK SEGMENT
+            In order to be converted to a COM file, an EXE file cannot
+            have a stack segment.
+
+        EXE HAS NONZERO CS
+            In order to be converted to a COM file, an EXE file must
+            have a code segment that begins at offset 0 of the code
+            image in the EXE file.
+
+        IP NOT 0 OR 100H
+            In order to be converted to a binary file, an EXE file must
+            have an entry point of 0 or 100H within the code segment.
+            For COM files, the entry point should be 100H.  For SYS
+            files (device drivers), the entry point should be 0.
+
+        PROGRAM EXCEEDS 64K
+            In order to be converted to a binary file, the total size of
+            the code to be loaded (including the PSP) must not exceed
+            64K bytes.
+
+        UNKNOWN ERROR
+            Internal error.  Notify the author.
+
+
+        Warning message
+        ---------------
+        EXE2COM has one warning message:
+
+            COM FILE, INITIAL IP NOT 100H
+
+        The entry point of all COM files should be 100H.  If you are
+        creating a COM file an the entry point is not 100H, EXE2COM will
+        do the job but let you know that there is a potential problem.
+

+About
+-----
+
+This set of programs is an addition to the Angelos Karageorgiou's vgagreek 
+DOS greek keyboard driver. The additions/modifications enable DOS programs to
+support the ELOT-928 (iso-8859-7) character set. By using the following 
+programs you'll be able to write and see greek in DOS using the the above 
+character set. The ELOT-928 character set is the greek character set used by
+most UNIX systems, on the internet, and is very similar to the one used by
+MSWindows. Windows uses a character set called "cp1253" which does not exist in
+any ISO standard. The letters are in the same place in this charset except the
+"A accented capital" (alpha tonoumeno kefalaio).
+
+The original vgagreek package, and Microsoft's command prompt display greek 
+using Memotek's 437gr (737) character set which is completely different from
+928. 
+
+The only problem you will have with the 928 charset in DOS is that the greek
+characters are in the place of the DOS "graphics" (lines,corners, et.c) so 
+instead of those you will see greek letters. This is not a problem if you
+use an editor such as vim which doesn't display those characters.
+
+Purpose
+-------
+I had an old 486 laptop with 2MB of memory. I wanted to use my old favourite
+DOS programms, but writing greek involved converting each time the files to
+the 928 charset with a filter. So I made the appropriate changes.
+
+Description/Instructions
+--------
+This package contains 2 programs:
+
+keygr928.com : this is a keyboard driver which enables you to write greek in 
+               the 928 character set. You must load this from autoexec.bat or
+               run it from command line. Only takes 1K of upper memory.
+               Toggle key between english and greek are:
+               Ctrl+"-"   and  Alt+1
+               You may change them by reading scancodes.txt and changing
+               the source file accordingly.
+
+               Ex: keygr928 or loadhigh keygr928
+
+vgablock.com: this is the original VGA function blocker for greek character 
+              set slightly modified to load different fonts. You must load this
+              to be able to see greek characters. It's a TSR and takes about 
+              14kb of memory. Its purpose is to load the appropriate fonts each
+              time you change screen resolution. It needs the fonts (*.fnt) to
+              be able to load.
+              *****
+              928 fonts are provided ONLY for 25 and 50 lines display. The 
+              other resolutions use the old 737 fonts.
+              
+              ex: vgablock
+
+setfont.com:  This utility is from the fonted program by Ivan Llanas. You can
+              use this instead of vgablock to load greek fonts. It doesn't 
+              occupy any memory at all, but fonts are lost when you change
+              screen resolutions (if you do) so you must re-run it. It is also
+              capable of changing screen resolution to match the font loaded.
+              ex: setfont 928-8x16.fnt
+
+vga25.com:    display 25-lines/screen. Does not need ansi.sys
+vga50.com:    display 50-lines/screen. Does not need ansi.sys
+
+
+The fonts:
+928-8x16.fnt :928 greek font. This size is the original 25 line-screen font size
+928c8x16.fnt :a caligraphic version of the above.
+928-8x8.fnt  :smaller version of the above for the 50-line resolution.
+
+** for the other resolutions I haven't made any 928 fonts. **
+
+gr*.fnt      :the old 737 encoded fonts of the original package.
+
+928.cpi:     CPI file to use with original DOS utilities. Includes the above
+             two fonts (928-8x16.fnt and 928-8x8.fnt)
+
+loadcpi.bat: example on how to load the above .cpi
+
+
+
+Installation
+------------
+1. remove all appearences of the following drivers from config.sys:
+   display.sys
+   country.sys
+   ansi.sys is not neaded.
+
+2. remove all appearences of the following from autoexec.bat
+   mode con codepage prepare/select
+   keyb
+
+
+3. At the end of autoexec.bat add the following:
+   lh keygr928
+   lh vgablock
+
+     OR
+
+  lh keygr928
+  setfont 928-8x16.fnt
+ 
+Of course you must first copy the programs to your disk.
