Batch File Programming – DOs and DON'Ts You must always follow best programming practice while writing codes, be it batch file programming or any. Even in short programs, we must maintain the habit of following better practice because while we write huge programs, it becomes a nightmare to debug it and also maintain it because no one else will understand your code if not properly documented. So here are the few things that must be implemented and few things that must be avoided while coding. DOs Documenting code with comments Perhaps this is one of the most important one because without proper documentation it becomes tedious to maintain the code and debug it. So it is always a good idea to insert comments in programs or codes, explaining what the next lines or block of code is trying to accomplish, how and why. Either REM or:: is used for comments in batch file programming. Here is the example. REM This is first comment:: This is another comment Validating input As simple as it is to code batch files, so is to hack and tweak the code because everything is like plain English in batch programs.
Preface This book 'Batch File Programming' is written after experimenting and testing all the snippets covered in this book. Batch File Programming is a pretty old one, but i have found lot of books that haven't covered the dark-side of the batch, which still remains untold. The ultimate goal of this book is to make the readers understand how it works, what are the limitations of the batch, what else is possible with a batch, constructing useful programs with various views, Creating a batch virus by mis-using the commands, creating a batch file to an executable and lot more. This book is aimed at novice to advanced programmer, No matter if you are new to programming, this would be the right drive to start with, since this book contains real time examples along with screenshots that really helps in a better understanding of the concept. First Edition May 2009 Acknowledgements First and foremost I would like to thank my Mum and Dad for their constant care and blessings. My Special thanks to Mr. C. Robinson (CEO, W3cert), for his kind encouragement in authoring this book more over I cannot forget to express my gratitude for my relatives and comrades.
