Function calls, returns, and the values returned are color-coded. The file is about 60K, so you might have to wait for it (school's connection is kinda slow). The main problem, as I can see, is that in the second `C-x v v', vc-file-getprop continually returns nil; it's as though pertinent information wasn't saved during vc-register or something similar. The third time through, vc-file-getprop returns the correct information. I'm not sure why initially registering the file doesn't set the information; it appears to get set during the second `C-x v v' in the call to vc-backend (call depth 10). But it's too late; we're already trying to check the file out. In the second call to `C-x v v', the function vc-file-clearprops is called (from vc-backend-admin, call depth 8 and 7, respectively); that looks suspicious, too. The above comments become much clearer after looking at the HTML file. :) The GNU Emacs (20.7) version of vc.el contains the following line in vc-register: (setq vc-buffer-backend (vc-backend (buffer-file-name))) which looks like it might fix some problems, but I don't think adding it last night did anything; I can try again. If there's anything else I can do, please let me know. I hope what I've done is helpful. -- </nathan> froydnj(a)rose-hulman.edu | http://www.rose-hulman.edu/~froydnj/ Yes, God had a deadline.
