NOTAB
 
  The NOTAB command indicates that a specified terminal does not have hardware
  horizontal tabs.
 
  The general format of the NOTAB commands is:
  NOTab                 ! Displays at the users terminal all terminals that
			  do not have hardware horizontal tabs.  The user is
			  prompted for a terminal, enter a carriage-return to
			  have all terminals displayed.
  NOTab TTn             ! Declares that terminal TTn: does not have hardware
			  horizontal tabs.  A nonprivileged user can display
			  all terminals set to NOTAB, but only declare this
			  for TI:.  A privileged user can specify any terminal.
 
  The NOTAB command performs the same function as SET /NOHHT .
 
  Note:   NOT        <=>   SET /NOHHT
	  NOT TT3    <=>   SET /NOHHT=TT3:
