Well, so is an apostrophe.  Fortran 77 standard only recognizes
apostrophe as teh delimiter for character constants.  No other
use is defined.

Ampersand is not even in the Fortran standard character set!  The
Fortran character set consists of 26 letters, 10 digits, the blank,
and the following: [=+-*/(),.$':].  (not counting the square brackets.)
Fortran 90 uses the ampersand for statement continuation in the Free
Form source syntax.
