Setting up a working environment for World Builder in Perl. Windows Download Active Perl (MSI installer for XP, zip file for Vista) and install. MSI installer in XP should set Perl in the path, you'll have to do this manually in Vista. The typical install is to C:\Perl, so the path to include will be C:\Perl\bin. I then create a directory named Code (C:\Code). I put my executable in there. There are a couple ways to run this program at this point. 1. Open a command window, cd to C:\Code and type perl world.pl For command line help type perl world.pl --help Otherwise, go to the program, double click on it, and then select the Perl executable as the program to run this file. If you're on XP and you installed Active Perl, this association has probably been done for you. In Vista, it's a manual process. At this point, double clicking the program will run the program Linux In most Linux distributions, perl is installed as part of the base distribution. You will also want to install 'perldoc' as well, as we use this program for help text. Once the program is installed, cd to the working directory chmod 744 world.pl (to make the program executable) ./world.pl if you want help, type ./world.pl --help Vista system path help: http://banagale.com/changing-your-system-path-in-windows-vista.htm Active Perl download (free download): http://www.activestate.com/store/activeperl/download David Myers.
