This document is written in pod format hence there are punctuation

ASCII->EBCDIC translation worked out correctly. You can read more
about pod in pod/perlpod.pod or the short summary in the INSTALL file.
You may need the following GNU programs in order to install perl:

We used version 1.2.4, which could be installed out of the box with
one failure during 'make check'.
-=head2 bison
+=head2 bison on BS2000
The yacc coming with BS2000 POSIX didn't work for us. So we had to
use bison. We had to make a few changes to perl in order to use the
add a few changes due to EBCDIC. See below for more details
concerning yacc.

To extract an ASCII tar archive on BS2000 POSIX you need an ASCII
filesystem (we used the mountpoint /usr/local/ascii for this). Now

There is a "hints" file for BS2000 called hints.posix-bc (because
posix-bc is the OS name given by `uname`) that specifies the correct

worked too.

We still got a few errors during C<make test>. Some of them are the
result of using bison. Bison prints I<parser error> instead of I<syntax

We have no nroff on BS2000 POSIX (yet), so we ignored any errors while
installing the documentation.
-=head2 Using Perl in the Posix-Shell

BS2000 POSIX doesn't support the shebang notation
(C<#!/usr/local/bin/perl>), so you have to use the following lines
First you get the BS2000 commandline prompt ('*'). Here you may enter
your parameters, e.g. C<-e 'print "Hello World!\\n";'> (note the
double backslash!) or C<-w> and the name of your Perl script.

+Filenames starting with C</> are searched in the Posix filesystem,
others are searched in the BS2000 filesystem. You may even use
wildcards if you put a C<%> in front of your filename (e.g. C<-w

possibilities of the commandline prompt (look for
PARAMETER-PROMPTING).
