Ditto First, I just woke up 10 minutes ago and still have 1/2 of cup of coffee, but the logic above looks wrong. do i = 1, 2, 1 print *, i end do should produce 1 2 Here, we have m1 = 1, m2 = 2, m3 = 1 > IF (M3 > 0 .AND. M1 < M2) GOTO 200 ! Loop executed zero times -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42131
