I am using the latest build.  I thought of a Temp table and maybe Indexes
but have not tried this  yet.

Thanks
Marc

Marc, 
I'm assuming that you are using the latest verison of V8 releasd on 4/20. 
There was an update last year specifically dealing with V8 indexes. 
 
Most of the reported speed issues with V8 have been external (network and 
Server 2003). 
 
While it may seem counter-intuitive, I have actually found some speed 
improvements 
by moving away from views and creating temp tables and appending limited data 
to the temp tables. 
 
There are a couple of articles that may help at http://www.razzak.com/fte named 
Gaining Speed with Programming in R:BASE 
Speeding Up Multi-User Environments 
 
Also I seem to remember John Minyo presenting a paper I think at the 2007 on 
programming for speed.

  The command below takes 2 times longer in V8 compared to the same code in 
7.5. 
  PRINT  NewForm76D  WHERE tr_date BETWEEN 1/1/09 AND .#date AND insco1 = 7  
  AND compnum = insco1 ORDER BY insco1, custnum, tr_date 
   
  The report is based on a 6 tab view,  Browse all from View using the same 
where clause only 
  takes 1/4 the time compared to the Print statement.  Leaving off the Order by 
does not make 
  any difference. 
   
  I am using a copy of the same DB converted to V8, so all data, reports and 
indexes are the same. 
   
  I did notice that the #1 file was 46 k now it is 191 k and the # 3 file is 
almost double the 
  size in V8.   Is that normal? 
   
  I am not sure what to look for next? 
   
  Thanks 
  Marc
