Sure. Say the data rows are events which contain, among other things, the following fields: -a date - an employeeID - a title (as in position in the company e.g. CEO). Usually, the title is filled in, but sometimes it's missing. When it's missing, it can be calculated by `(employees detectID: employeeID) titleOn: timestamp`*, but if it's present, you should just use the value in the field because the lookup is inconsistent and expensive. Thanks for following up! * The timestamp is necessary because you're actually searching through the employment history to see the title on that particular date in the past. ----- Cheers, Sean -- View this message in context: http://forum.world.st/NeoCSV-Interdependent-Field-tp4914190p4914200.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
