# Grab a web page - structured programming example
# This example uses structured programming techniques
# where each logical element of the program is written
# as a sub call - a hierarchy of code that's fitted
# together like a pyramid. Why do this?
# 1. It makes the code more readable
# 2. It makes the code more re-usable
# 3. It makes the code easier to test
# 4. It makes the code easier to maintain
# Get a client's connection to the host ...
# Turn buffering OFF on the socket
# Have our chat with the server
@response = do_httpd("/course/index.html");
# Turn buffering back on
# Use what you got!
@linkies = getlinks(@response);
Here's how it runs:
