Thanks to Kit Baum, a new package -iquantile- is now available from SSC.
This was discussed yesterday in my post
<http://www.hsph.harvard.edu/cgi-bin/lwgate/STATALIST/archives/statalist
.0901/date/article-689.html>
in a thread on fractional medians. I changed the problem, and the name,
but had fun. A capsule description follows my signature. The help file
is quite detailed with much commentary. Use -ssc inst iquantile- to
install if interested.

interpolation in the mid-distribution function. The user may specify one
or more numeric variables, one or more grouping variables and one or
