<h1><a name="getting_started_with_perl_ix">Getting Started with Perl/iX</a></h1>
<p>Create your Perl script files with &quot;#!/PERL/PUB/perl&quot; (or an
equivalent symbolic link) as the first line.  Use the chmod command to
make sure that your script has execute permission. Run your script!</p>
<p>Be sure to take a look at the CPAN module list
( <a href="http://www.cpan.org/CPAN.html">http://www.cpan.org/CPAN.html</a> ). A wide variety of free Perl software
is available.  You can automatically download these packages by using
the CPAN module ( <a href="http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html">http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html</a> ).</p>

<h1><a name="mpe_ix_implementation_considerations">MPE/iX Implementation Considerations</a></h1>
<p>There some minor functionality issues to be aware of when comparing
Perl for Unix (Perl/UX) to Perl/iX:</p>
<ul>
<li>
<p>MPE gcc/ld doesn't properly support linking NMPRG executables against
NMXL dynamic libraries, so you must manually run mpeix/relink after
each re-build of Perl.</p>
</li>
<li>
<p>Perl/iX File::Copy will use MPE's /bin/cp command to copy files by
name in order to preserve file attributes like file code.</p>
</li>
<li>
<p>MPE (and thus Perl/iX) lacks support for setgrent(), endgrent(),
setpwent(), endpwent().</p>
</li>
<li>
<p>MPE (and thus Perl/iX) lacks support for hard links.</p>
</li>
<li>
<p>MPE requires <code>GETPRIVMODE()</code> in order to <a href="../../lib/Pod/perlfunc.html#item_bind"><code>bind()</code></a> to ports less than 1024.
Perl/iX will call <code>GETPRIVMODE()</code> automatically on your behalf if you
attempt to <a href="../../lib/Pod/perlfunc.html#item_bind"><code>bind()</code></a> to these low-numbered ports.  Note that the Perl/iX
executable and the PERL account do not normally have CAP=PM, so if you
will be bind()-ing to these privileged ports, you will manually need
to add PM capability as appropriate.</p>
</li>
<li>
<p>MPE requires that you <a href="../../lib/Pod/perlfunc.html#item_bind"><code>bind()</code></a> to an IP address of zero.  Perl/iX
automatically replaces the IP address that you pass to <a href="../../lib/Pod/perlfunc.html#item_bind"><code>bind()</code></a> with
a zero.</p>
</li>
<li>
<p>MPE requires <code>GETPRIVMODE()</code> in order to setuid().  There are too many
calls to <code>setuid()</code> within Perl/iX, so I have not attempted an automatic
<code>GETPRIVMODE()</code> solution similar to bind().</p>
</li>

<h1><a name="perl_ix_todo_list">Perl/iX To-Do List</a></h1>
<ul>
<li>
<p>Make <code>setuid()/setgid()</code> support work.</p>
</li>
<li>
<p>Make sure that <a href="../../lib/Pod/perlfunc.html#item_fcntl"><code>fcntl()</code></a> against a socket descriptor is redirected to sfcntl().</p>
</li>
<li>
<p>Add support for Berkeley DB once I've finished porting Berkeley DB.</p>

<h1><a name="perl_ix_change_history">Perl/iX Change History</a></h1>
<p>May 6, 1999</p>
<ul>
<li>
<p>Patch LBCJXT6A is required on MPE/iX 5.5 machines in order to prevent
Perl/iX from dying with an unresolved external reference to _getenv_libc.</p>
</li>
</ul>
<p>April 7, 1999</p>
<ul>
<li>
<p>Updated to version 5.005_03.</p>
</li>
<li>
<p>The official source distribution once again compiles &quot;straight out
of the box&quot; for MPE.</p>
</li>
<li>
<p>The current incarnation of the 5.5 POSIX filename extended
characters patch is now MPEKX40B.</p>
</li>
<li>
<p>The LIBSHP3K *.a -&gt; *.sl library conversion script is now included
as /PERL/PUB/LIBSHP3K.</p>
</li>
</ul>
<p>November 20, 1998</p>
<ul>
<li>
<p>Updated to version 5.005_02.</p>
</li>
<li>
<p>Fixed a DynaLoader bug that was unable to load symbols from relative
path name libraries.</p>
</li>
<li>
<p>Fixed a .xs compilation bug where the mpeixish.sh include file wasn't
being installed into the proper directory.</p>
</li>
<li>
<p>All bugfixes will be submitted back to the official Perl developers.</p>
</li>
<li>
<p>The current incarnation of the POSIX filename extended characters
patch is now MPEKXJ3A.</p>
</li>
</ul>
<p>August 14, 1998</p>
<ul>
<li>
<p>The previous POSIX filename extended characters patch MPEKX44C has
been superseded by MPEKXB5A.</p>
</li>
</ul>
<p>August 7, 1998</p>
<ul>
<li>
<p>The previous POSIX filename extended characters patch MPEKX76A has
been superseded by MPEKX44C.</p>
</li>
</ul>
<p>July 28, 1998</p>
<ul>
<li>
<p>Updated to version 5.005_01.</p>
</li>
</ul>
<p>July 23, 1998</p>
<ul>
<li>
<p>Updated to version 5.005 (production release).  The public
freeware sources are now 100% MPE-ready &quot;straight out of the box&quot;.</p>
</li>
</ul>
<p>July 17, 1998</p>
<ul>
<li>
<p>Updated to version 5.005b1 (public beta release).  The public
freeware sources are now 99.9% MPE-ready.  By installing and
testing this beta on your own HP3000, you will be helping to
insure that the final release of 5.005 will be 100% MPE-ready and
100% bug free.</p>
</li>
<li>
<p>My MPE binary release is now extracted using my standard INSTALL script.</p>
</li>
</ul>
<p>July 15, 1998</p>
<ul>
<li>

scripts more easily and efficiently.</p>
</li>
</ul>
<p>July 8, 1998</p>
<ul>

<p>Updated to version 5.004_70 (internal developer release) which is now
MPE-ready.  The next public freeware release of Perl should compile
&quot;straight out of the box&quot; on MPE.  Note that this version of Perl/iX
was strictly internal to me and never publicly released.  Note that
[21]BIND/iX is now required (well, the include files and libbind.a) if
you wish to compile Perl/iX.</p>
