Currently not, but I like this suggestion for various reasons.
For compatibility with Windows 95 long filenames, the generated short
filename for a long file name will be truncated using tildes +
numbers, so the SFN will usually be MY.L~1, MY.L~2, etc., but not
MY.LIS. Since this is actually stored in the file system, there is no
reasonable way to achieve a "truncated long file name" like MY.LIS
afterwards.
However, as long as there are not multiple files with matching SFNs
IMO also it would be more convenient, if LONGNAME would optionally
(!) generate an SFN by just truncating the LFN, so that the SFN for a
LFN like MY.LIST would actually be MY.LIS, as Mark suggests. Of
course, once there are matching SFNs, LONGNAME should again default
to use the tilde + number method. (BTW. Windows 95 has a registery
setting to force this behaviour.)
Additionally I'd like to suggest to implement another LONGNAME option
to reduce junk in the directory entries to a minimum: Optionally
LONGNAME should generate LFNs only for filenames not fitting in the
8.3 naming scheme, else it should only generate the SFN directory
entry, and no LFN storing the case.
Regarding the question, where to report LFN bugs: Just use the
usual Caldera email address as stated in the README.TXT file
shipping with the driver and/or DR-DOS.

As far as I see it, using F-PROT (on a DR-DOS 7.03 BETA system with or
without SHARE loaded) this applies to all files which have the Hidden
and/or System attribute set, not only to the DR-DOS kernel files. I'm
not sure why this happens, but it is probably due to the method F-
PROT uses to open files. However, it does not occur on the MS-DOS 7
command prompt.
Has anyone checked this under MS-DOS 6.22 with and without SHARE
loaded?

No, only the task switcher can swap to disk. The multitasker currently
does not provide virtual memory, however it surely would be very
useful to add this.
