Perl 5 README file for the Stratus VOS operating system. Paul Green (Paul_Green@stratus.com) August 12, 1998 Introduction ------------ This is a port of Perl version 5, revision 005-02, 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. Most of the Perl features should work on VOS.

They are "dup", "execlp", "execl", "execvp", "fork", and "waitpid". Compiling Perl 5 on VOS ----------------------- Before you can build Perl 5 on VOS, you need to have or acquire the following additional items. 1.

While the necessary header files are included in this distribution, you still need the appropriate object files in order to bind perl.pm. This is a standard Stratus product. 3. The VOS POSIX.1 environment. As of this writing, this is available on the VOS FTP site. Login to ftp.stratus.com anonymously 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. To build build 5, change to one of the VOS object directories (e.g., perl5.005_02>vos>obj), and give the command "
