Hey Ward!

Possibly but from my past experience I believe it has to do with line lengths
on tty's, line printers, and the such which were as a rule 80 characters wide.
The 'missing' 8 characters had to do with margins if I am not mistaken. As for
the null terminator that is a hangover from strings being terminated with
nulls. I am unsure where that idea originates but I suspect pre-F77 FORTRAN.
Life is good,
Maurice
