12.3.8.5 line_length.l (FTANGLE)

This parameter is used by the FORTRAN-like languages to control the length of the output line in the .f file produced by FTANGLE. For FORTRAN-77, its default value is the venerable 72. For FORTRAN-90, its default is 73. Using that value makes it possible to generate code that is compatible with both fixed- and free-form format (by continuing lines with an trailing ampersand in column 73 and another ampersand in column 6 of the next line).
