PROGRAM TP_LOGIN -- Two-Person Login


	This program implements a Secondary Login capability.  The
	process is not allowed to continue unless a second user gets
	'logged in' by this program.

	This program must be run at the very beginning of SYLOGIN.COM.
	All users' authorization records must include the flags:

		DEFCLI  and  DISCTLY

	The call to this program in SYLOGIN.COM should look like:

		$   SET NOON		  ! Beginning of SYLOGIN.COM
		$   RUN dev:[dir]TP_LOGIN
		$   STOP /ID=0
		$ TP_LOGIN_COMPLETE:
		$   . . .

	This program needs to be installed with SYSPRV privilege.

	To try it, execute @TPLOGIN.  Your process will get stopped
	if you don't sucessfully complete the secondary login.

	I would appreciate comments on this program.
