The next step in your evolution as a CGI programmer is to learn how to customize scripts for your own needs. Thus, the first task is to understand how CGI programs are structured. Many CGI programs use a common toolbox of routines-called libraries . Thus, it is helpful to understand how libraries work Web applications are not ferocious. After a bit of delving into the lines of code, you'll often find that a well-written program can be tame.
Algorithms are like ants in an ant colony, each doing one small job well.
To decipher a program, you need only focus on understanding how these simple packets of code, called subroutines, interact. If you understand the program one routine at a time, the application's design will emerge and you will be more comfortable modifying and adding to the original program. Let's look at each of these types. INT Media Group, Incorporated. All Rights Reserved.
