Ask DEC -- they upgraded the length of the VAX/VMS filenames some
time back. You better not ask _how_ they did it 'tho; you might
be sick. They didn't (and I am talking as a system programmer about
the time the change was made, things may have been cleaned up
since) make the filename _contiguous_ in the (directory) entry --
there happened to be a bit of space left over at the end and...

In U*X a directory entry is defined in dir.h -- you _may_
redefine the maximum length & recompile. Why have you got only
14-char filenames? Is this _really_ V?
