I reran the dpara check under OS/2 2.0 on my machine with those flags -FPi87 -G2 -AL -Od, and surprise surprise, MS Fortran 5.1 came out with only one SERIOUS DEFECT (after milestone 160), and completed the test. But, BTW, for 1./0., the answer was, as before, 1. And interestingly, Paranoia did not flag that as being a problem. (Dov: I could uuencode my dpara.exe and e-mail it to you. That would let us establish whether the difference we note is between 5.0 and 5.1 or between your and my machine.) Luc
