Five hours ??? Using the performance script you sent me Howard, and using the 749 length sting, the algorithm im using takes 7 SECS (the entire running time)!!!

KiXtart Golf Score
Tournament = KiXtart Golf: Burrows-Wheeler Transform
Start (Date/Time) = 2002/12/22 12:01:21
Finish (Date/Time) = 2002/12/22 12:01:28
KiXGolf Result = passed
KiXGolf Score = 267

The actual Decoder UDF itself takes about 441 msecs How come so long ???
