Perl Multimedia Cyber Classroom  README

NOTE 1:
Due to limitations with the Java Media API, some of the longer audio files occasionally may not play to completion. If you experience this problem you can locate and open any audio file provided with this Cyber Classroom. To do so:

  1. Using File Manager, locate the directory perlbyex on the CD-ROM.
  2. If you have WinZip installed, double click on the audio.zip file found in this directory. If you don't have WinZip installed, you will need to locate a copy. Try http://www.tucows.com.
  3. Clicking on the audio.zip file with WinZip installed will show a listing of all the audio. Locate the file you want to play and extract it to your hard drive.
  4. Once the file is on your hard drive you will be able to play the file using the Windows Media Player.
NOTE 2:
The Copy to Disk function displays a file with a .jar extension in the Copy To Disk dialog box when the Copy To Disk icon is pressed. However, when you press the Save button in the Copy To Disk dialog box, the contents of that jar file are extracted to your disk, not the jar file itself. These contents are the Perl source code.

NOTE 3:
Because some of the Module Examples require packages that produce no output, execution of the Example script from the Run Code icon is not possible. In order to limit confusion, in these Examples the Run Code icon has been removed.

NOTE 4:
Your server may require the CGI script names to end in a .cgi extension rather than .pl and HTML files to end in .htm rather than .html. You will have to install these sample programs under your server's root directory in either cgi-bin or HtDocs. This will all depend on your server configuration.
You will have to change pathnames in the links if testing these files as they will be different on your system.
If using Perl on a Win32 platform, the #!line will not work. To test the scripts, type: perl -c scriptname.

NOTE 5:
Many of the UNIX system calls will not be supported on Win32 type systems. For example, gethostbyname returns an error that there is no socket support.
