I suppose if you are really perverse you could define enough logicals to
cover all possible sorting combinations :-)

Please respond to

I usually use embedded SQL to provide dynamics sorting on a subfile. I
also provide a position to by adding a where clause in the SQL. If you went
back to native I/O, you would loose the dynamic sorting capabilities.
Thanks,
