The Teach Yourself to be a Dummy in 24 Hours Bible

My forthcoming 987 page useless computer book.

Pick any of these great editions for just $19.95, or buy all 4 for just $79.95!

1. The Teach Yourself to be a Dummy in 24 Hours Bible, Windows 95 edition.
2. The Teach Yourself to be a Dummy in 24 Hours Bible, Windows NT edition.
3. The Teach Yourself to be a Dummy in 24 Hours Bible, Windows MacOS edition.
4. The Teach Yourself to be a Dummy in 24 Hours Bible, Windows LINUX edition.

All editions come with poor typography, CD ROM, ugly front cover, unrecognizable photograph of the author on the rear cover, essential index (with wrong page numbers), and an error on every page!

Sample from the WWW Chapter:

The CGI programing langugage is used to write HTML scripts for the Internet. It's commands include:

• void main(int argc);
• </meta>
• $i = $i++;
• Start button.

Of course other commands are supported, depending on if which computing language you are installed in the IDE: Visual Basic (Beginner's All Systems Instruction Code), Visual Perl, Visual COBOL, or Visual C/C++. See your online help for more details, this is just a sample!

Review question:

Can you understand why this function works?

sub is_integer_prime {
  ('.' x ($_[0]+1) !~
/^(..+)\1+$/;}
