Bad command or file name
The "Bad command or file name" message appears when you type something that MS- DOS does not recognize. Because nul is not a valid MS-DOS command, MS-DOS displays the "Bad command or file name" message.

ver 
The following message appears on your screen:
MS-DOS version 6.2.9200 (it may be diffident on different OS)
