At least in SCOPE and KRONOS, DMP was the command to dump memory--but if
initiated from a user's control point, it would dump only the user's FL,
not the whole system.  So the story seems to be a bit apocryphal to me.
  Most university systems charged not only by the CPU second, but also
by the number of lines printed and the number of cards punched.
