When I write out a file (using C-X C-W), and I try to change some part of the pathname, the system will also change the file type from TXT to TEXT. Does anyone know how to prevent this? This only appears to happen with TXT files and it causes me to end up with different versions of the same file (some with TXT and some with TEXT). I usually do this when the host on which I read the file has crashed and I wish to write it to a different host. The hosts are clustered under VMS, so it doesn't matter which one I use. Thanks, Bob krovetz@cs.umass.edu

Maybe the easiest way to "fix" this would be to remove the canonical file type for :text, i.e. change: fs: (DEFINE-CANONICAL-TYPE :TEXT "TEXT" ((:TOPS20 :TENEX :VMS4) "TEXT" "TXT") (:UNIX "TX" "TEXT" "TXT") (:UNIX-UCB "TEXT" "TX" "TXT") ((:MSDOS :VMS) "TXT")) into your prefered mapping.

This probably has to do with canonical file types on the Explorer. I
believe the canonical file type :TEXT translates to the VMS file extension
"TXT". But on the Explorer it translations to "TEXT". Look at the
variables: FS:*CANONICAL-TYPES-ALIST* & FS:*DEFAULT-CANONICAL-TYPES* (I'm
guessing at the names of these variables, it's been awhile since I've
messed with 'em). The I/O Ref Manual might yield some help on how to
adjust these variables to get the behavior you want.
One workaround, that I know this is not very convenient, is when you do c-x
c-w specify the pathname type and that should override the Explorer's
defaulting to the canonical file type.

Except that I've had the same problem that Bob had on my MicroExplorer, with no VMS machines anywhere in sight (or any other remote machines). It seems to me that it should *never* change any part of a filename that I don't change myself (irrespective of any mappings or settings). Bruce
