Sometimes, scriptwriters skip important steps in their haste to get code into production. Scripting is essentially the process of translating our thoughts into another language. If you want to write a good script, you need to make sure your translation is as clear and complete as possible.
Writing your script in pseudo-code first can help clarify the eventual flow of the script and identify the elements necessary for the script to work properly. Pseudo-coding can save you time because it lessens the chance that you'll later discover faulty coding logic. Pseudo-coding also helps you segment the code into sections in a given script or modules that can become subroutines in the script.
The DeleteMP3.pl script in this article's Listing 1 contains a basic Recurse module that you can modify slightly to perform many functions. Table A shows how pseudo-code translates between English and Perl code.
