Dear Maher,
the BXDRAW entry of MGDRAW can be activated, for instance, with a
WHAT(3)=2 in the USERDUMP card.
However: think twice before using this for your problem in
case you are going to make use of biasing! The management of weights might
be a critical thing. You need at least a USRBDX estimator to check what
your doing.
Anyway, all infos that you mentions are accessible by the (TRACKR)
common. Unfortunately the manual might still contain some mistake: you
have to look inside the (TRACKR) file that is contained in the flukapro
subdirectory inside $FLUPRO:
$ more $FLUPRO/flukapro/\(TRACKR\) (or cat, lpr, etc.)
