Hi,<BR><BR>I&#039m trying to create a look-up table for days of the year, i.e., Jan 1 = 1, Jan 2 = 2, etc... I need to do this because I&#039m using the day of year in equations and I think it would be easier to do the math with integers rather than dates and convert back with a LUT when displaying the output.<BR><BR>An Access db would add a lot of overhead... is there a way to do this with a text file? Any good samples out there?<BR><BR>Thanks a lot,<BR>geoff
