The return value from UNIX is 16 bits wide. The leftmost 8 bits are the lowest 8 bits of the exit() value. The rightmost 8 bits indicate why it stopped e.g. normal exit, Segmententation violation, breakpoint in a debugger (via trace()). run x.4ge returning y let y = y/256. >My system: Informix v. 5.04 on HP-UX 10.01 > >Thanks, >Michael Hoffman >(Yes, Jake, it's me asking another "brilliant" question! :-}) > > -- David Williams
