I have options set so that comments should not be touched when
formatting a region, but they are indented to the current indentation
level. It is a bit of a pain to use a regular expression search and
replace to get them back where they belong.

Thanks for the report, but please give a complete example of what you
mean, starting from emacs -Q.

O.k. The program shows up with emacs -Q with this program
program tmp
integer :: i
do i = 1, 5
! Comment
print '("i=",i0)', i
end do
end program tmp
Highlight the whole program, then <cntrl><alt>\
and the ! Comment is indented, and I think this should not happen.
Thanks for looking into this.

Why do you think it should not happen?
F90 mode has always behaved like this.
Earlier you said:

> formatting a region,
What options are those?

I'm hoping that just because it has "always" done this, that does not
make it correct.

fortran-comment-indent-style is a variable defined in `fortran.el'.
Its value is nil
Original value was fixed
This variable is safe as a file local variable if its value
satisfies the predicate which is a byte-compiled expression.
Documentation:
How to indent comments.
nil forces comment lines not to be touched;
`fixed' indents to `fortran-comment-line-extra-indent' columns beyond
`fortran-minimum-statement-indent-fixed' (if `indent-tabs-mode' nil), or
`fortran-minimum-statement-indent-tab' (if `indent-tabs-mode' non-nil);
`relative' indents to current Fortran indentation plus
`fortran-comment-line-extra-indent'.
You can customize this variable.
Specifically nil forces comment lines not to be touched. When you get
down to it, I don't care what nil does, but I certainly want some way to
say "don't change my comments". But from the above, that seems to be
what nil is supposed to do. I'd be happy if there was some choice that
did this, but here is what I see for choices
Fortran Comment Indent Style:
(*) Untouched
( ) fixed
( ) relative
State : SAVED and set.
How to indent comments. Hide
nil forces comment lines not to be touched;
`fixed' indents to `fortran-comment-line-extra-indent' columns beyond
`fortran-minimum-statement-indent-fixed' (if `indent-tabs-mode'
nil), or
`fortran-minimum-statement-indent-tab' (if `indent-tabs-mode'
non-nil);
`relative' indents to current Fortran indentation plus
`fortran-comment-line-extra-indent'.
Groups: Fortran Indent
I have fortran-comment-line-extra-indent set to 0. Perhaps there is
some combination in there that would make it do what I want, but since
it appears that nil should do the job, I've filed this report.
Many thanks for looking into this.
Fred

Fortran mode is not F90 mode. They don't have all the same features,
and fortran- variables have no effect on F90 mode. It's a bit
unfortunate that we ended up with "fortran" mode meaning "F77", but here
we are.

I guess now this turns into a new feature request. I'd love to have
some way to leave comments untouched (the nil in Fortran mode). Looking
in the f90 settings, I don't see any way to do this.
Thanks,
Fred

You should be able to (ab)use f90-directive-comment-re for this:
(setq f90-directive-comment-re "!")
I don't really want to add a feature for this since AFAIK other
programming modes don't have such a thing. Fortran mode is different
because comments are weird in old-school F77.

I don't know about the abuse, but it works, and I'm very happy to have it.
Many Thanks,

You could make f90 follows the "3 comment chars" convention, as
in Lisp.

How 'bout we rename fortran.el to f77.el, change the "fortran-" prefix
to "f77-" (and add obsolete aliases where needed)?

Probably the right thing to do; but: Once I had some vague hope to make
"fortran-mode" a smart thing that chose the correct mode, f77 or f90 (or
f95 or f2000 or ...), based on the filename/contents, but it never
happened and shows no sign of doing so. Without a realistic expectation
of that second step, the first step of renaming things will just annoy
people for no reason, so I can't see much point.
