Almost any program that runs under Perl 5.8 will still run on Perl 5.18, especially programs in a book for beginners (the opposite would not be true). There must be something that you are not doing right when typing or copying and pasting the source code. Please provide a verbatim example of a program that does not run on your computer.

One possible explanation is that the "shebang line" (something like #!/usr/bin/perl at the top of the program does not correspond to the place where Perl is installed on your computer. Try to type which perl at the shell prompt to check where Perl is installed.

Je suis Charlie.
