 notation of the form 6.626D-34.  Is it correct for me to assume that this
 represents 6.626*10^(-34), and is equivalent to the scientific notation
 6.626E-34 or 6.626e-34 used in other areas, such as in C/C++, Python, and
 MATLAB?  Or does the "D" represent anything different from, or in
 addition to, "*10^"?

 Dear Andrew:
 You are right that "D” just represents "*10^”.
 The D specifier informs you that the number printed was a double-precission real
 number in the FORTRAN program. You can find more about this by searching for
 FORTRAN formats.
