Hi,
The maximum line length in Fortran 90 is 132.
Here's a good site for getting the info inside the Fortran standards,
which
are annoyingly hard for ggggooooooooooooooooogggggggggggggggggggggle to
find:

15 + 76 + 45 = 136
So even without the consideration of whether the max line length
includes the &, that line is too long.
However, it looks like Dave fixed this in revision 1.12.
Nevertheless, there are still many lines that are longer than 80
characters;
many people find such lines inconvenient to read.
