Redirection works now in DOS. So you can have a text file that contains
a CR/LF and add to the time command line as:

			time < cr_lf.txt

and the ^M will be sent to the needed time prompt as if typed in.
Example:
		login.bat :

			time < cr_lf.txt
			... (other commands)

		cr_lf.txt :
			    (just an empty line, ^M is there)

So CR/LF will be automaticly entered at the time command line and you
make the login.bat bypass the time prompt.
This is also helpful to erase all files from a diskette that an app-
lication prompt users to put in a formatted old diskette, and call
up the system's DOS to do a del a:*.* < yes.txt, where yes.txt 
contains only a 'y' and a ^M to satisfy the 'Are you sure (Y/N)?' prompt.
