Difference between batch processing and doscommand

Batch processing can be run on the DOS system or Windows system, so the batch processing command is more than the DOS command, basically composed of the DOS command, but some process control commands are added, such as |, <,>,>, NUL, and so on.
In addition, batch processing can reference external programs. For example, a Regedit can open the registry on a Windows system. batch processing contains very powerful functions, the batch processing in DOS is much more than the DOS command. The identification of the DOS command and the external program mainly relies on the priority of the file name and extension than the.exe in the same directory, you can directly write a line in the batch processing to automatically use a.exe.
Most of the batch processing is composed of a line of some DOS commands, and then the batch processing can continuously execute such a line of commands, but some commands are not doscommands.
