st: merge within a range

hi,
I have the following merge problem. In one data set I have a start date
and and end date (and, of course, several other variables); in another
data set I have a particular date. I want to merge the two data sets
with a match occurring if the "particular" date in data set 2 is between
(or equal) to the startdate/enddate in data set 1.
An obvious kludge is to expand the first data set and fill-in the dates
to be consecutive. If possible, however, I prefer not to do this and am
looking for any suggestions.
thanks,
Rich
