Andrew Despite the message wording, I am pretty sure 'date' is a centreline property, rather than an 'survey' property. The surveys just inherit the range of dates from their centrelines.

From memory, which is often faulty, any centreline with survey shots ('data' statements) will trip this warning if there is a cs defined (globally) but there is no date in that centreline.

One that caught me out once was adding data nosurvey etc in a centreline of it's own - I had to add a date that the shot was not surveyed! (Also that nosurvey shots actually add their lengths to the surveyed length) So to answer your question, I cannot think of an easy way, unless creating a sql output and then querying that will work for you. Not sure if Dave Clucas' project http://sarawak-caves.com/php/websearch.php could be made to seek out undated surveys as it stands? The 'Lengths' query has a field for dates, but I don't think 'undated' will work. I guess if the output had 'approx', 'date' and 'explo-date' columns, you could scan down the table for blanks.
