In S+ and S it was valid to pass logicals to .Fortran, where they got mapped into the appropriate bit pattern. (The trouble was that 'appropriate' was compiled into the program - so you were locked into our compiler vendor's choice). Passing them between Fortran code and C code has always been a problem (as has passing character data between them).
