I posted some clarifications regarding what I am trying to do in my answer to the previous reply. Basically I am trying to match each number (e.g. 200210201) in datafile2 to any of the the given ranges in datafile1. If the number in datafile2 is within a range in datafile1 than it is a match. I used the concatenation of the two numbers in datafile1 to establish a unique 'rangeid' to be used as the hash key. In other words, '2 200534011 200577234 some text description' has a hash id of 20052. I then read each line of datafile2 and check through the record set to see if I find a hash key that matches (has the same 4 first numbers--i.e.2005). If so then I look closer at the sid and eid.

I am just trying to find out better, more efficient ways of doing this. :)

Thanks!

David
