I'm a Sun user that is very impressed (isn't everyone) with the
new 700 series.  I would consider purchasing these machines, but
have never used HP-UX.

From reading various messages in this group, I have gotten
the following impressions: 1. HP-UX 8.0 supports shared libraries;
2. HP-UX 8.0 does NOT support memory-mapping of files.

Is point 2 correct?  If so, how does HP-UX implement shared libraries?
Certainly under SunOS, the shared libraries are brought into the
process address space by mapping the files.

What's the real story?  In my opinion, memory-mapping is a very
powerful tool, and one I am not eager to do without.
