GNU Emacs 22.0.50.1 (i386-mingw-nt5.0.2195) of 2006-03-28. Does it work if you pass the required second arg to string-match: (read-file-name "File: " nil nil nil nil (lambda (name) (string-match "wantname" name))) I don't think "resulting from completion" is relevant when MUSTMATCH (the fourth arg) is nil. -- Kevin Rodgers
