-Introduction
-------------
-This is a port of Perl version 5, revision 005-63, 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.
+Note that there are two different implementations of POSIX.1
+support on VOS. There is an alpha version of POSIX that is
+available from the Stratus anonymous ftp site
+(ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html). There
+is a generally-available version of POSIX that comes with the
+VOS Standard C compiler and C runtime in VOS Release 14.3.0 or
+higher. This port of POSIX will compile and bind with either
+version of POSIX.
-Most of the Perl features should work on VOS. However, any
+Most of the Perl features should work on VOS regardless of which
+version of POSIX that you are using. However, the alpha version
+of POSIX is missing a number of key functions, and therefore any
attempt by perl.pm to call the following unimplemented POSIX
functions will result in an error message and an immediate and
fatal call to the VOS debugger. They are "dup", "fork", and
"waitpid". The lack of these functions pretty much prevents you
from starting VOS commands and grabbing their output in perl.
The workaround is to run the commands outside of perl, then have
-perl process the output file.
+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.
+=over 5
+
+=item 1
+
+The VOS Standard C Compiler (or the VOS Standard C
+Cross-Compiler) and the VOS C Runtime. If you are using
+the generally-available version of POSIX support, you may
+instead use the the VOS GNU C/C++ Compiler. These are
+standard Stratus products.
+
+=item 2
-2. The VOS OS TCP/IP product set. While the necessary header
- files are included with VOS POSIX.1, you still need the
- appropriate object files in order to bind perl.pm. This is
- a standard Stratus product.
+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. The VOS POSIX.1 environment. As of this writing, this is
- available on the VOS FTP site. Login anonymously to
- ftp.stratus.com and get the file
- /pub/vos/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. This is not a standard Stratus product.

+Either the alpha or generally-available version of the VOS
+POSIX.1 environment.
-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.

+are at ftp://ftp.stratus.com/pub/vos/utility/utility.html.
+This is not a standard Stratus product.
+
+In VOS Release 14.3.0, the generally-available version of
+POSIX.1 support is bundled with the VOS Standard C compiler
+(or Standard C Cross-Compiler). In VOS Release 14.4.0 or
+higher, it is also bundled with the VOS C Runtime. These
+are standard Stratus products.

+execute on VOS Release 12 or earlier.
+
+=item 5
+
+If you are using the generally-available version of VOS
+POSIX support, then you should also acquire the VOS GNU
+C/C++ Compiler and GNU Tools product. When perl is built
+with this version of POSIX support, it assumes that it can
+find "bash", "sed" and other POSIX-compatible commands in
+the directory /system/gnu_library/bin.
+
+=back
To build perl 5, change to the "vos" subdirectory and type the
command "compile_perl -processor X", where X is the processor
type (mc68020, i80860, pa7100, pa8000) that you wish to use.
+Note that the generally-available version of POSIX.1 support is
+not available for the mc68020 or i80860 processors.
+
+Use the "-version alpha" control argument to build perl with
+the alpha version of POSIX support, and use the "-version
+ga" control argument to build it with the
+generally-available version of POSIX. The default is "ga".
+
+Use the "-compiler cc" control argument to build perl with
+the VOS Standard C compiler. Use the "-compiler gcc"
+control argument to build it with the GNU GCC compiler. The
+default is "cc".
+
+You must have purchased the VOS Standard C Cross Compiler in
+order to compile perl for a processor type that is different
+from the processor type of the module.
+
Note that code compiled for the pa7100 processor type can
-execute on the PA7100, PA8000, and PA8500 processors, and that
-code compiled for the pa8000 processor type can execute on the
-PA8000 and PA8500 processors.

-Unimplemented Features
-----------------------
-If Perl 5 attempts to call an unimplemented VOS POSIX.1 function,
-it will print a fatal error message and enter the VOS debugger.
-This error is not recoverable. See vos_dummies.c for a list of
-the unimplemented POSIX.1 functions. To see what functions are
-unimplemented and what the error message looks like, compile and
-execute "test_vos_dummies.c".

+=head2 Restrictions of Perl on VOS
-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; I don't know much
-about Perl itself; I'm still learning that. There are some
+can't guarantee I'll be able to answer them. There are some
excellent books available on the Perl language; consult a book
seller.
