dbx90 is a front-end to gbd/dbx that is Fortran 90 aware. 
You can find the man page at:
http://www.nag.co.uk/nagware/np/r41_doc/dbx90.html
and you will notice that the syntax is a bit peculiar.

I've been thinking for a while to take some time to add some support
in ddd but I was unfortunately too busy. That's not very difficult but 
somewhat tedious.
