are detected, then the file is assumed to be in fixed source form. The

Fixed-form Fortran requires a maximum line length of 72 characters but the
script allows a maximum line length of 80 characters as do all compilers
created in the last three decades. An even longer line length of 132

More precise fortran syntax ~
If you set the variable fortran_more_precise with a command such as >
:let fortran_more_precise=1
then the syntax coloring will be more precise but slower. In particular,
statement labels used in do, goto and arithmetic if statements will be
recognized, as will construct names at the end of a do, if, select or forall
construct.
Non-default fortran dialects ~
The syntax script supports two Fortran dialects: f08 and F. You will probably
find the default highlighting (f08) satisfactory. A few legacy constructs
deleted or declared obsolescent in the 2008 standard are highlighted as todo
items.
If you use F, the advantage of setting the dialect appropriately is that
other legacy features excluded from F will be highlighted as todo items and
that free source form will be assumed.
The dialect can be selected in various ways. If all your fortran files use
the same dialect, set the global variable fortran_dialect in your vimrc prior
to your syntax on statement. The case-sensitive, permissible values of
fortran_dialect are "f08" or "F". Invalid values of fortran_dialect are
ignored.
If the dialect depends upon the file extension, then it is most convenient to
set a buffer-local variable in a ftplugin file. For more information on
ftplugin files, see |ftplugin|. For example, if all your fortran files with
an .f90 extension are written in the F subset, your ftplugin file should
contain the code >
let s:extfname = expand("%:e")
if s:extfname ==? "f90"
let b:fortran_dialect="F"
else
unlet! b:fortran_dialect
endif
Note that this will work only if the "filetype plugin indent on" command
precedes the "syntax on" command in your vimrc file.
Finer control is necessary if the file extension does not uniquely identify
the dialect. You can override the default dialect, on a file-by-file basis,
by including a comment with the directive "fortran_dialect=xx" (where xx=F or
f08) in one of the first three lines in your file. For example, your older .f
files may be legacy code but your newer ones may be F codes, and you would
identify the latter by including in the first three lines of those files a
Fortran comment of the form >
! fortran_dialect=F
For previous versions of the syntax, you may have set fortran_dialect to the
now-obsolete values "f77", "f90", "f95", or "elf". Such settings will be
silently handled as "f08". Users of "elf" may wish to experiment with "F"
instead.
The syntax/fortran.vim script contains embedded comments that tell you how to
comment and/or uncomment some lines to (a) activate recognition of some
non-standard, vendor-supplied intrinsics and (b) to prevent features deleted
