 label STR                             Write a label

   MLABEL writes the string STR at the current location (set by MOVE,
   etc). The string's size and angle are determined by EXPAND and
   ANGLE. The character "\" is an escape character and causes the
   following actions:

                   \\x - set mode x
		   \x - set mode x for next char only

		   \r - roman font
		   \g - greek font
		   \s - script font

		   \t - tiny font

		   \i - toggle italics

		   \u - superscript

		   \d - subscript

		   \e - end string

   The string orientation is determined by the local North (i.e., is

   perpendicular to that line) in the map data coordinate system (DCS).
