Batch File Programming By Chand2
Batch file programming is nothing but the Windows version of Unix Shell
Programming. Let's start by understanding what happens when we give a DOS
command. DOS is basically a file called command.com It is this file (command.com)
which handles all DOS commands that you give at the DOS prompt---such as COPY,
DIR, DEL etc. These commands are built in with the Command.com file. (Such
commands which are built in are called internal commands.).DOS has something
called external commands too such as FORMAT,
UNDELETE,...
