Dear SAS-L,

   Thanks to all your replies.  As noted by one biostatistician, I'm looking
for the 0.995 quantile or 99.5 percentile.  Not the 99.5 quantile as my
subject line reads.  I stand corrected.  This is what happens when
non-statiscians use SAS <g>.  In any event, I think Zdeb proposed the most
common-sense solution.  Namely:

   av_P995 = ( av_max - av_P99 ) / 2;

  - Jack
