Reply To: How can I apply a func to a grouped table?

Thanks soo much! Only a small and last question. Is there anything special about the table?

I used

rev:{stock xcols update stock:key x from (value x)[AskOrder],'(value x)[BidOrder]} r; <br>ddd: string dt[i][date2]; 
save hsym $":/Users/void_dump/Desktop/Reverse/", ddd,"/rev.csv"</pre><p>ddd is a string of date, e.g. '2014.01.01'</p><p>I've done this several times before and they all work well. But this time it says</p><pre>'type<br>  [0]  save hsym$":/Users/void_dump/Desktop/Reverse/", ddd,"/rev.csv"
       ^

I searched but didn’t see a solution. This rev table isn’t a keyed one, nor is it very special, I don’t see why there would be a bug here…
