fortran-line-length is a variable defined in `fortran.el'.
Its value is 72

   Automatically becomes buffer-local when set in any fashion.
   This variable is safe as a file local variable if its value
   satisfies the predicate `integerp'.

Maximum number of characters in a line of fixed-form Fortran code.
Characters beyond this point are treated as comments.  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).  This corresponds to the g77 compiler option

You can customize this variable.

This variable was introduced, or its default value was changed, in
version 23.1 of Emacs.
