deleting old stocks

[traders10@xxxx]

I am trying to identify and delete some old stocks I no longer want 
to follow. I wrote an exploration to find these stocks, which are no 
longer being updated. The desired stocks are being updated.

I thought if I looked for close < $1, on Fri, 9/07 using valuewhen 
and datenum I would get a list of those stocks that are not being 
updated. Instead they do not show up at all. It seems as if the 
explorer throws out stocks that are not up to date. This might not 
be a good idea, if true.

So, clever people, how do I identify these stocks and delete them 
easily from the database. (It should not be a problem in the future 
now that we can import to a watch list.) 

BTW, Tomasz, when are you going to add this importing feature to 
AmiFeed, which is what I use to import data?
TIA
