Ran into an issue with the 2008 version above, it caused Filemaker to use many GB's memory within 30 seconds and becoming unresponsive when getting columns from a (large) set of data. Found modified version which solved this entirely on the following page, from Mike_Mitchell https://community.filemaker.com/message/171033#171033
