The World of DOS - Creating Batch Files

Batch Files
What are batch files? Batch files are not programs, pre se, they are lists of command line instructions that are batched together in one file. For the most part, you could manually type in the lines of a batch file and get the same results, but batch files make this work easy. Batch files do not contain "compiled" code like C++ so they can be opened, copied and edited. They are usually used for simple routines and low-level machine instruction, but they can be very powerful. If you look in your C:\, C:\WINDOWS, or C:\WINNT folder you will see a multitude of .BAT, .SYS, .CFG, .INF and other types. These are all kinds of batch files. This may shock you, but while most applications are writen in Basic or C++ they sit on a mountain of batch files. Batch files are the backbone of the Windows operating system, delete them and you've effectively disabled the OS. There is a reason for this. The system batch files on each computer are unique the that computer and change each time a program is loaded. The operating system must have access to these files and be able to add and delete instructions from them.
