Why do you want to put it in one loop? As far as I can see (and it was painful to look at that code, you owe me Naomi, you owe me big time :)) those were independent values, so I would write two methods with only one loop to do the assignments (and those methods should have a descriptive name, with the names you are currently using nobody can understand what the heck they are pop1 and pop2), this way if tomorrow for some reason there are 11 and 14 columns and you are not there any longer the next person has an easier job maintaining the code. (also I think in the foxpro code you have another set (criteria? I forgot and I already deleted the quoted text) that I would put in yet another method but is missing in your code, I think)

Just my 2c
