UCX$IPC_SHR is an executive-mode logical name pointing to a
    shareable image supplied by your TCP/IP vendor. If this logical
    is not defined, then either TCP/IP is not installed, or, in the
    case of a package other than DEC's TCP/IP Services for OpenVMS
    (a.k.a. UCX), UCX emulation was not installed when the package
    was installed. In order to use the TCP/IP functionality of
    PMDF Pine, this logical must be defined and be pointing to the
    appropriate image for your TCP/IP package. Moreover, the image
    must be installed as a known image,

    $ INSTALL UCX$IPC_SHR /OPEN/SHARED

    If you are running Pine on a system without any TCP/IP software,
    a dummy shareable image PMDF_EXE:UCX_DUMMY.EXE is provided with
    PMDF. Your system manager should define a system-wide, executive-
    mode logical named UCX$IPC_SHR which points to it and then
    install it:

    $ DEFINE/SYSTEM/EXEC UCX$IPC_SHR PMDF_EXE:UCX_DUMMY.EXE
    $ INSTALL UCX$IPC_SHR /OPEN/SHARED

                                   NOTE

       If you install any TCP/IP package later, remember to
       deassign the logical name or you won't have a functional
       TCP/IP.

    The definition of the logical and installation of the image
    should be made part of the system startup procedure. Note that
    the installation of the image can be effected through the site-
    supplied PMDF_COM:SITEIMAGE.DAT file which uses the same format
    as the Process-supplied PMDF_COM:PMDFIMAGE.DAT file.
