Hi, I am trying to calculate two or more Elog fields and then return the value to Elog. I am currently learning Perl to do this. I realize JS can do this.. but so can IBM Basic ;)  I am savy with other db techniques like sql. My question is before I get too far along with this project, is it safe to say the current storage of Elog data is 'Flat File' database? I also want to find out if it would be better to try and grab the data prior OR  after it gets into the Elog database. I see there are other forum messages related to sql interfacing and such, but nothing conclusive.  I will submit my personal progress here. Thanks again, John
