I'm working with a large data set in Excel, over 38,000 rows. I'm trying to
combine two such sets, then do some pivots, but because the combined table is
too large, I need to eliminate some unecessary data.

My approach so far has been to pull in the first set, then run through each
row to find the rows I can eliminate, then delete each one. In this case,
I'm trying to delete any row with "2007" as the year. Everything seems to be
working, but once the code finds the 2007 rows, it's taking a very long time
to run through the data. I've already turned off screen refresh, and set
calculation mode to manual, but it's still taking a very long time.

When I run though the code step by step, I don't detect any pauses or
problems deleting the rows. It seems to run thorugh process very quickly.

Is there any reason why this should take a long time? Is there a better
approach for doing this?

Thanks,
Todd
