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).
