I have two datasets that were nonmatch merged and I need to get the number of data points of the using data set that are within various radii of each of the unique levels of the master data set. To be clear, both data sets have longitude and latitude coordinates in decimal degrees. Now, I have tried the -circnum- user-created command, but I think it only calculates points within radius of one pair of coordinates. I need something a little more sophisticated.

Can anyone help?
