Sorry, I meant "might be the case" in reference to "I never saw Fortran 
used for systems programming before".  (Also, "might be the case" 
essentially means "while that is the case" in this context.)

I just wanted to suggest that it was an implementation choice, and not 
due to some deficiency in Fortran itself (as far as I know).
