My understanding is that it should have no effect on the number of 
observations.
Its effect is to insure that when the program exits, the data are 
left in the same sort order as before.
That may or may not be desirable, depending on your needs.
It may take a little extra run-time.

I have written one program where I made it an option -- whether to 
run it as sortpreserve. There was a little trick to make that happen, 
which I can explain if you want.
