Hi All:<br>
<br>
If you really need to do large sorts you can improve your
performance by <br>
writing to a subfile and then doing a VMS sort over which you
have more control.<br>
<br>
This issue has come up on this list before.<br>

makes the code more readable, by simplifying the Access statement, and it also
reduces the record complex so could improve performance. Beyond that I am
trying to remember if there are any more advantages (perhaps for one, if you're
reaching the no of files limit, it doesn't count).</span><span
