Perhaps you're not setting it correctly in .emacs. Try, in a .pro buffer,
C-h v comment-add. It should say something like:
comment-add is a variable defined in `newcomment.el'.
Its value is 1
Local in buffer foo.pro; global value is 0

This is the correct behavior, since any comment starting at the
beginning of the line is not moved when indenting. If you always want
it to indent no matter where point is, perhaps inset " ;{{{" instead.
By the way, for "folding", the next version of IDLWAVE will support
HideShow, which lets you collapse blocks (routine definitions or
otherwise) with a few keystrokes. Very useful, and no comment
trickery required. A hidden function, for instance, look like:
function my_func,arg1,arg2...
but contains the full collapsed text. Sometimes I find it useful to
collapse (C-c @ C-M-h) everything, and then show a few functions at a
time. You can also hide any control block.

In that case just stick it in the global map.
(define-key global-map
[f6]
'(lambda () (interactive)
(insert (concat " " comment-start "{{{"))
(indent-according-to-mode)))

The M-; trick does not work despite the addition of the "command-add"
parameter and that's why I am perplexed.

For anyone wanting to try it the define-key trick works great, though
it only indents if the cursor is not in column 1. Which I guess is how
idlwave indents comments in the first place. In case you're curious, I
use ;{{{ and ;}}} with folding.el to fold IDL code in emacs, pretty
nifty.
I realize this is an IDL forum and not an emacs forum but I will give
this a shot anyway...
I think the super-uber version of the define-key command above would
act slightly differently: it would insert the string "{{{", prepend the
relevant comment characters for the current mode and finally indent the
whole thing properly. Is *this* possible or am I just asking too much
of either xemacs or this fine community?
Many thanks,
Gianguido

It only works with the stanza in .emacs that I provided. The next release
won't need this, but for now, you must set the "comment-add" parameter.

Yes, indeed. You might add something like this to your idlwave-mode-hook
inside of .emacs:
(define-key (current-local-map)
[f6]
'(lambda () (interactive)
(insert ";{{{")
(indent-according-to-mode)))
The same pattern can be used to insert anything.

I am running xemacs 21.4.15 and idlwave 5.1 and I get a different
behaviour:
on a blank line I get ";" at the beginnig of the line independantly of
indentation. What do you think is going on? Feel free to just tell me
to upgrade :-)
While we are on the subject, is there a way to associate a key sequence
in xemacs to inserting a set string, say ";{{{" ***with the
appropriate indentation*** ?
Thanks,
Gianguido

I actually didn't know about M-;, thanks.
By default, comments starting with ";" are indented to the right
(usually after a line of code), those starting with ";;" are indented
to the code indent location, and those starting with ";;;" are not
moved at all. Also, any comment starting at the very beginning of the
line is left there (regardless of how many semi-colons it starts
with).
The best way to get what you want is to set `comment-add' to 1
locally, by adding to your idlwave-mode-hook in .emacs:
(add-hook 'idlwave-mode-hook
(lambda ()
(set (make-local-variable 'comment-add) 1)))
In fact, I like this so much I'm adding it to the next version of
IDLWAVE. It also affects C-c ; (comment-region -- for the better I
think).
For those of you who want to try M-;, with this fix, on a blank line it
indents and puts in ";; ", on a line with code, it moves to the right
of the code with a ";". Really quite useful. For the curious, M-; calls
`comment-dwim'... "do what I mean" indeed.
Thanks for the suggestion.
JD

Short answer: use ';;' instead of ';'
More helpful answer:
In IDLWAVE mode you can bring up help for the mode with C-h m (or menu
IDLWAVE:Documentation:Describe Mode), which says, in part:
Comments are indented as follows:
`;;;' Indentation remains unchanged.
`;;' Indent like the surrounding code
`;' Indent to a minimum column.
The indentation of comments starting in column 0 is never changed.
Hope this helps!
