MAHAL <data>,<output_line>
computes Mahalanobis distances as a variable activated by `D'
and/or their cumulative probabilities according to
Chi^2 distribution activated by `P'
from other active variables in <data>.
If the data is sorted by the `P' or `D' variable,
the `P' variable plotted against (ORDER-0.5)/N should give
a straight line when the data is a sample from a multinormal
distribution.
