Do you mean "repack your data set" as in using Adager/Dbgeneral to 
reorganize the data set (which I can't do in a 24x7 environment)?  
Or "repack your data set" as in delete all entries while writing 
them to a flat file, sort the flat file, and then add the records 
back in (which I can do, but I don't think it will reset the high 
water mark)?
