-------------
-This is a port of Perl version 5, revision 7, to VOS. Perl
-is a scripting or macro language that is popular on many
-systems. See your local computer bookstore for a number of good
-books on Perl.
+=head2 Stratus POSIX Support
Note that there are two different implementations of POSIX.1
support on VOS. There is an alpha version of POSIX that is
perl process the output file. These functions are all available
in the generally-available version of POSIX.

+=head2 Compiling Perl 5 on VOS
-Compiling Perl 5 on VOS
------------------------
Before you can build Perl 5 on VOS, you need to have or acquire the
following additional items.
-1. The VOS Standard C Compiler and Runtime, or the VOS Standard C
- Cross-Compiler. This is a standard Stratus product.
-
-2. Either the VOS OS TCP/IP or STCP product set. If you are
- building with the alpha version of POSIX you need the OS
- TCP/IP product set. If you are building with the
- generally-available version of POSIX you need the STCP
- product set. These are standard Stratus products.
-
-3. Either the alpha or generally-available version of the VOS
- POSIX.1 environment.
-
- The alpha version of POSIX.1 support is available on the
- Stratus FTP site. Login anonymously to ftp.stratus.com and
- get the file /pub/vos/posix/alpha/posix.save.evf.gz in
- binary file-transfer mode. Or use the Uniform Resource
- Locator (URL)
- ftp://ftp.stratus.com/pub/vos/alpha/posix.save.evf.gz from
- your web browser. Instructions for unbundling this file
- are at ftp://ftp.stratus.com/pub/vos/utility/utility.html.
- This is not a standard Stratus product.
-
- The generally-available version of POSIX.1 support is
- bundled with the VOS Standard C compiler and Runtime (or
- Cross-Compiler) in VOS Release 14.3.0 or higher. This is a
- standard Stratus product.
-
-4. You must compile this version of Perl 5 on VOS Release
- 14.1.0 or higher because some of the perl source files
- contain more than 32,767 source lines. Due to VOS
- release-compatibility rules, this port of perl may not
- execute on VOS Release 12 or earlier.

To build perl 5, change to the "vos" subdirectory and type the
command "compile_perl -processor X", where X is the processor
that code compiled for the pa8000 processor type can execute on
the PA8000, PA8500 and PA8600 processors.
+=head2 Installing Perl 5 on VOS
-Installing Perl 5 on VOS
-------------------------
-1. Create the directory >system>ported>command_library.

-2. Copy the appropriate version of the perl program module to
- this directory. For example, with your current directory
- set to the top-level directory of Perl 5, to install the
- executable program module for the Motorola 68K
- architecture, enter:

!copy_file vos>obj>perl.pm >system>ported>command_library>*
- (If you wish to use both Perl version 4 and Perl version 5,
- you must give them different names; for example, perl.pm
- and perl5.pm).

+=head2 Unimplemented Features
-Unimplemented Features
-----------------------
If perl is built with the alpha version of VOS POSIX.1 support
and if it attempts to call an unimplemented VOS POSIX.1
function, it will print a fatal error message and enter the VOS
functions are unimplemented and what the error message looks
like, compile and execute "test_vos_dummies.c".
+=head2 Restrictions
-Restrictions
-------------
This port of Perl version 5 to VOS prefers Unix-style,
slash-separated pathnames over VOS-style greater-than-separated
pathnames. VOS-style pathnames should work in most contexts, but
See the file pod/perlport.pod for more information about the VOS
port of Perl.
+=head1 SUPPORT STATUS
-Support Status
---------------
I'm offering this port "as is". You can ask me questions, but I
can't guarantee I'll be able to answer them. There are some
excellent books available on the Perl language; consult a book
seller.
