Quite right.  We were interested in reuilding our file systems on our
HP 9000/350 system so that it would be more compatible with our existing
Sun network.  However, for us there was a major gotcha which forced us
to keep the 14-character limitation:  this system hosts HP's MDE
environment (the 64000/UX hardware with in-circuit emulators, etc.),
and our salesperson told us that the MDE will break if we change the
file system.

Hi,

I'm an R & D project manager for the HP MDS system and I might be
able to clear up the question about long file names.

    Your HP64000 MDS software will work on a long file name system as
    is presently stands.  Just don't use long file names.  What this
    means is that any file name longer than 14 characters will be 
    truncated.  Consequently, you may name a file "abcdefghijklmnopq"
    but it will be truncated to "abcdefghijklmn" which is confusing
    to the user.  The option test software which validates the
    funtionality of the emulation hardware WILL break as it presently
    stands.  The solution is to use the HP-UX command ln() to
    create a file called "pvxxxxfile_asmb" from the file "pvxxxxfile_asm".

We are working on changing some of our products to actually take
advantage of long file names but the changes are not close to 
being ready.


Please let me know if I can be of further assistance.
