Microsoft released a version of cmd.exe for Windows 9x and ME called WIN95CMD to allow users of older versions of Windows to use certain cmd.exe-style batch files. As of Windows 8, cmd.exe is the normal command interpreter for batch files; the older COMMAND.COM can be run as well in 32-bit versions of Windows able to run 16-bit programs.
Another important use of the echo command is to toggle echoing of commands on and off in batch files. Traditionally batch files begin with the @echo off statement.

Changes made to the command line environment after SetLocal commands are local to the batch file. EndLocal command restores the previous settings. [17] The Call command allows subroutines within batch file. The Call command in COMMAND.COM only supports calling external batch files. File name parser extensions to the Set command are comparable ...
In computing, start is a command of the IBM OS/2, [1] Microsoft Windows [2] and ReactOS [3] command-line interpreter cmd.exe [4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program. The underlying Win32 API is ShellExecute.
