RE: compare using qry or logical

["Dan Bale" <dbale@xxxxxxxxxxxxx>]

It depends.

Once a logical is built, you don't have the same overhead to create the
access path as you would with OPNQRYF.  Dynamic Select affects this, but
it's been awhile since I've dealt with that.

If this is used "often", it's probably best to define a logical.  If rarely
used, like once monthly, just keep using the OPNQRYF.  If used in a lot of
applications, even if rarely, probably easier maintenance to define a
logical.

YMMV.
