Date: Mon, 28 Mar 2005 10:07:21 -0600 From: Bill Long <[log in to unmask]> Bitwise complement is NOT(i); see section 13.7.87 in the standard. Thanks. I probably knew that once. (Also in the intrinsics section of my "Fortran 90 Handbook.") I suppose it is an accident of history it isn't called INOT() which would be name-consistent with IAND(), IOR() and IEOR()?
