I am reporting a bug in emacs version 24.5.1. It appears both on a
mac an on a linux machine.
Some functions in fortran fixed-format mode, with lines exceeding 72
columns (132 for example), still assume a 72 column width, independent
of the value of variable fortran-line-length
In particular sexp operations like (forward-sexp) assume characters
past 72 columns are comments.
Consider the attached "example.f" : Read the file with
emacs -Q example.f
Change variable fortran-line-length :
(set-variable (quote fortran-line-length) 132 nil)
so that now:
(describe-variable (quote fortran-line-length))
returns:
fortran-line-length is a variable defined in `fortran.el'.
Its value is 132
Original value was 72
Local in buffer example.f; global value is 72
Move the point just after test1, so it precedes the first expression (..).
In this case forward-sexp works as expected.
Move the point just after test2, so it precedes the second expression (..).
In this case forward-sexp fails to find the end of the expression.
Note also that "twelve)" is highlighted as though it is a comment.
This problem does not appear in emacs 21.4

Thanks for the report. However, as it says in
C-h v fortran-line-length
Setting this variable directly (after fortran mode is loaded) does
not take effect. Use either M-x customize (which affects all Fortran
buffers and the default) or the function `fortran-line-length'
(which can also operate on just the current buffer).
So: use
C-u 132 M-x fortran-line-length

The variable fortran-line-length does not exist in 21.4.
