Hi Marco, 
I would be very interested in being able to use this macro, integrated or not, since in my project there are numerous figures with lots of references to them throughout the entire text, and \at{page}[] is not satisfactory for me.

I tried the code you supplied by pasting the whole lot into a TeXShop-file, and, when that did not work, in Alphax, processing  the latter from Terminal, but in both cases I received an error message that I do not know what to do with. Strangely enough it complains about an error in line 1 even if that contains a commented out comment.

I reproduce the error message  here, hoping that you, or somebody elsm, can see what I did wrong. 
(I apologize on behalf of TeXShop and Alhax for the length of this message.)

Thanks in advance for any help.
