ASM allowed in Fortran? and OpenDir?

[RadSurfer]

I was just curious if there was such a thing as discreet assembly code ever
being allowed inside a Fortran program...
Perhpas that seems like a ludicrous question -- but I'll have to wait to see
what the replies are.

My guess is it is extremely rare and highly unheard of.
Since gcc permits linking with C-files and C-files are permitted use of 
ASM blocks, there's one obvious workaround...

One other question, seriously:
I did not notice any functions/extensions/etc. which permit the getting of
directory information which allows to "walk through" files...
I refer to "opendir" or "findfirst" type of directory-walking functions.
I realize there are extensions which allow information about _known_ files
to be returned... but not retreiving files from a directory to be placed
into a list for processing and that sort of functionality.

Thanks!
