The .Fortran call to "dqrqty" in qr.qty does not specify DUP which means it defaults to TRUE. I have looked through the fortan code for dqrqty and routines it calls and also done some testing but cannot find any reason that would cause a problem with DUP=FALSE. I realize this is considered the "risky" option, but the change can result in considerable memory saving in some problems. Can this .Fortran call can be changed?
