Can this be done faster ?

[John Miller]

JB,

I once wrote an inventory control program for a company using  
Revolution.  They had many thousands of items that I read out of  
their database and then sorted and processed.

I found that using a repeat for that many items was extremely slow.   
The solution that I found which made things blazingly fast was to  
only process about 50 items at a time.

For instance:


put 50 into XX
put the ticks into timer
repeat until listXX is empty
   put line 1 to XX of listXX into listYY
   delete line 1 to XX of listXX
   repeat with x = 1 to (number of lines in listYY)
      doaction to line x of listYY
   end repeat
end repeat
put the ticks - timer


Using the format above, you can experiment to see which value for XX  
is the most advantageous. I was able to whittle my time down from 45  
seconds to less than 1.

Good Luck
