+README_zOS.txt for version 7.3 of Vim: Vi IMproved.

-Welcome to the OS/390 Unix port of VIM.
+This readme explains how to build Vim on z/OS.  Formerly called OS/390.
+See "README.txt" for general information about Vim.

-ATTENTION: THIS IS AN _ALPHA_ VERSION!!!
-I expect you to know how to handle alpha software!
+Most likley there are not many users out there using Vim on z/OS. So chances
+are good, that some bugs are still undiscovered.

-This port was done by Ralf Schandl <schandl@de.ibm.com>.
-This port is not maintained or supported by IBM!!
+Getting the source to z/OS:
+==========================

+First get the source code in one big tar file and ftp it a binary to z/OS. If
+the tar file is initially compressed with gzip (tar.gz) or bzip2 (tar.bz2)
+uncompress it on your PC, as this tools are (most likely) not available on the
+mainframe.

-For the list of changes see runtime/doc/os_390.txt.
+To reduce the size of the tar file you might compress it into a zip file. On
+z/OS Unix you might have the command "jar" from java to uncompress a zip. Use:
+        jar xvf <zip file name>
+
+Unpack the tar file on z/OS with 
+        pax -o from=ISO8859-1,to=IBM-1047 -rf vim.tar
+
+Note: The Vim source contains a few bitmaps etc which will be destroyed by
+this command, but these files are not needed on zOS (at least not for the
+console version).


 Compiling:
----------
+==========

-Note: After the file configure was created via autoconf, it had been
-      handedited, to make the test for ICEConnectionNumber work.
-      DO NOT run autoconf again!
+Vim can be compiled with or without GUI support. For 7.3 only the compilation
+without GUI was tested. Below is a section about compiling with X11 but this
+is from an earlier version of Vim.

-Without X11:
+Console only:
+-------------

 If you build VIM without X11 support, compiling and building is nearly
-straightforward. The only restriction is, that you can't call make from the
-VIM toplevel directory. Change to the src directory first and call make from
-there. Here is a what to do:
+straightforward. 
+
+Change to the vim directory and do:

    # Don't use c89!
-    # Make additional symbols visible.
    # Allow intermixing of compiler options and files.

    $ export CC=cc
-    $ export CFLAGS=-D_ALL_SOURCE
    $ export _CC_CCMODE=1
-    $./configure --enable-max-features --without-x --enable-gui=no
+    $./configure --with-features=big --without-x --enable-gui=no
    $ cd src
    $ make
+
+      There may be warnings:
+        - include files not found (libc, sys/param.h, ...)
+        - Redeclaration of ... differs from ...
+        -- just ignore them.
+
    $ make test

-      Note: Test 28 will be reported as failed. This is because diff can't
-	    compare files containing '\0' characters. Test 11 will fail if you
-	    don't have gzip.
+      This will produce lots of garbage on your screen (including error
+      messages). Don't worry.
+
+      If the test stops at one point in vim (might happen in test 11), just
+      press :q!
+
+      Expected test failures:
+        11: If you don't have gzip installed
+        24: test of backslash sequences in regexp are ASCII dependent
+        42: Multibyte is not supported on z/OS
+        55: ASCII<->EBCDIC sorting
+        57: ASCII<->EBCDIC sorting
+        58: Spell checking is not supported with EBCDIC
+        71: Blowfish encryption doesn't work

-Hint:
-----
-Use the online help! (See weaknesses below.)
-
-Example:
-Enter ':help syntax' and then press <TAB> several times, you will switch
-through all help items containing 'syntax'. Press <ENTER> on the one you are
-interested at. Or press <Ctrl-D> and you will get a list of all items printed
-that contain 'syntax'.
-
-The helpfiles contains cross-references. Links are between '|'. Position the
-cursor on them and press <Ctrl-]> to follow this link. Use <Ctrl-T> to jump
-back.
-
-Known weaknesses:
-----------------
-
- You can't call make from the toplevel directory, you have to do a 'cd src'
-  first.  If you do it, make will call configure again. I don't know why and
-  didn't investigate it, there were more important things to do. If you can
-  make it work drop me a note.
-
- The documentation was not updated for this alpha release. It contains lot of
-  ASCII dependencies, especially in examples.
-
- Digraphs are dependent on code page 1047. Digraphs are used to enter
-  characters that normally cannot be entered by an ordinary keyboard.
-  See ":help digraphs".
-
- Using 'ga' to show the code of the character under the cursor shows the
-  correct dec/hex/oct values, but the other informations might be missing or
-  wrong.
-
- The sed syntax file doesn't work, it is ASCII dependent.
-
-Bugs:
-----
-If you find a bug please inform me (schandl@de.ibm.com), don't disturb Bram
-Moolenaar. It's most likely a bug I introduced during porting or some ASCII
-dependency I didn't notice.

 3. Writing help files					*help-writing*

-TODO
+For ease of use, a Vim help file for a plugin should follow the format of the
+standard Vim help files.  If you are writing a new help file it's best to copy
+one of the existing files and use it as a template.
+
+The first line in a help file should have the following format:
+
+*helpfile_name.txt*	For Vim version 7.3	Last change: 2010 June 4
+
+The first field is a link to the help file name. The second field describes
+the applicable Vim version. The last field specifies the last modification
+date of the file. Each field is separated by a tab.
+
+At the bottom of the help file, place a Vim modeline to set the 'textwidth'
+and 'tabstop' options and the 'filetype' to 'help'.  Never set a global option
+in such a modeline, that can have consequences undesired by whoever reads that
+help.
+
+
+TAGS
+
+To define a help tag, place the name between asterisks (*tag-name*).  The
+tag-name should be different from all the Vim help tag names and ideally
+should begin with the name of the Vim plugin. The tag name is usually right
+aligned on a line.
+
+When referring to an existing help tag and to create a hot-link, place the
+name between two bars (|) eg. |help-writing|.
+
+When referring to a Vim option in the help file, place the option name between
+two single quotes. eg. 'statusline'
+
+
+HIGHLIGHTING
+
+To define a column heading, use a tilde character at the end of the line. This
+will highlight the column heading in a different color. E.g.
+
+Column heading~
+
+To separate sections in a help file, place a series of '=' characters in a
+line starting from the first column. The section separator line is highlighted
+differently.
+
+To quote a block of ex-commands verbatim, place a greater than (>) character
+at the end of the line before the block and a less than (<) character as the
+first non-blank on a line following the block. Any line starting in column 1
+also implicitly stops the block of ex-commands before it.  E.g. >
+    function Example_Func()
+	echo "Example"
+    endfunction
+<
+
+The following are highlighted differently in a Vim help file:
+  - a special key name expressed either in <> notation as in <PageDown>, or
+    as a Ctrl character as in CTRL-X
+  - anything between {braces}, e.g. {lhs} and {rhs}
+
+The word "Note", "Notes" and similar automagically receive distinctive
+highlighting.  So do these:
+	*Todo	something to do
+	*Error	something wrong
+
+You can find the details in $VIMRUNTIME/syntax/help.vim
