[amibroker] Another AQ Question

[Ken Close]

As I load symbols into AQ and fetch data, a bunch of symbols are reported as
errors, obviously symbols which have changed names or are no longer listed.
 
My question is whether there is a convenient way to purge the database of
the out of date symbols, by somehow reading the window of results for those
having errors, and then turning that into some mass deletion list.
 
Does such a method exist?
 
Thanks.
Ken
