That should be 'last 31 years'. Fortran IV *was* call-by-value, as
least for scalars. I remember spending a couple of hours tracking down
an obscure 'bug' in a once-working program when I ran it with F77. (I
had not noticed the call-by-reference switch.) The reason was, as I
remember, 'x = -x' in a function. I never forgot the difference.
I've used it for 30 years
Then you apparently missed the switch ;-).
