What Are Batch Files & How to develop Batch Calculator?
Batch files allow MS-DOS and Microsoft Windows users to create a lists of commands to run in sequence once the batch file has been executed. For example, a batch file could be used to run frequently run commands, deleting a series of files, moving files, etc. A simple batch file does not require any special programming skills and can be done by users who have a basic understanding of MS-DOS commands.
A good example of a batch file for someone who is more familiar with Windows or the MacOS is to think of a batch file as a shortcut in Windows or an icon on the MacOS. Much like a shortcut, batch files could be used to run one or more commands or programs through the command line.
Another example of a very well known batch file is the autoexec.bat, which is a simple boot file loaded each time the computer is loaded on MS-DOS and early Windows computers. This batch file contained all the necessary commands and programs used to run MS-DOS and Windows each time the computer booted.
