The first dataset (one) represents people (pid) and where they live (cid). The second data set (two) has where they live (cid) and a set of possible product choices (pho). I need a dataset that has, for each person, all the choices they face.  Note: the choice set changes based on where they live.  The below illustrates my issue.  The actual data has 90,000 persons living in 180 different locations that on average will have 20 choices.  The output data file will have approx. 1,800,000 obs.

Data one; input pid cid;
datalines;
1 1
2 1
3 1
4 2
5 2
;
data two; input cid pho;
datalines;
1 1
