          Whether you are a new or a continuing VAXELN Ada customer,
          please take time to read the following information about your

          New VAXELN Ada customers should receive the following:

          o  The media required for Version 2.2 of VAXELN Ada

          o  User documentation

          o  Supplemental materials and any additionally ordered items

          o  Supplemental materials and any additionally ordered items

          Installation Information

          o  VMS Version 5.4 or higher

          o  VAXELN Version 4.1 or higher

          If you are installing VAXELN Ada Version 2.2 on a newly-licensed
          node or cluster, you must first register a License Product
          Authorization Key (License PAK) using the License Management
          Facility (LMF). The License PAK may be shipped along with the
          kit if you ordered the license and media together; otherwise, it
          is shipped separately to a location based on your license order.

 






          If you are installing VAXELN Ada Version 2.2 as an update on
          a node or cluster already licensed for this software, you must
          register the Service Update PAK (SUP) that is included in your
          Service Update Kit. If you already registered a License PAK or a
          SUP for this product on this node or cluster, you do not need to
          register the SUP.

          If you are installing an update of VAXELN Ada but lack a service
          contract, call your Digital representative for instructions on
          how to get a License PAK.

          See the VMS License Management Utility Manual for registration
          instructions.

          Previous versions of VAXELN Ada do not need to be installed
          before this version.

          You should use the Version 2.2 kit name (VAXELN_ADA022) when in-
          voking
          VMSINSTAL.

          You can read the release notes before installing VAXELN Ada by

          Compatibility Information

          Before installing VAXELN Ada Version 2.2, you should read the
          release notes. The release notes contain important information
          on the compatibility of VAXELN Ada Version 2.2 with previous
          versions of VAXELN Ada. In particular:

          o  VAXELN Ada Version 2.2 requires VAX Ada Version 2.0 or
             higher. Beginning with Version 2.0, VAX Ada uses a program
             library format that is incompatible with the format for pre-
             vious versions of VAX Ada. For more information, see the VAX
             Ada release notes.

          o  The package VAXELN_SERVICES has been bundled with VAX Ada
             since VAX Ada Version 1.4. This package has had some spec-
             ification corrections and changes in VAX Ada Versions 2.0,
             2.1, and 2.2. You do not need to reenter this package as a
             result of installing VAXELN Ada Version 2.2. However, you
             may need to modify your source files to accommodate any
             changes made to VAXELN_SERVICES in a VAX Ada release. For
             more information, see the VAX Ada release notes.

          o  If you are using VAX Ada Version 2.2, then you need VAXELN
             Ada Version 2.2. You cannot use the VAX Ada Version 2.2 com-
             piler as the compiler for VAXELN Ada Version 2.0 or earlier.

          o  The shareable image ADA$FMATH.EXE is no longer provided
             in the VAXELN shareable image library ELN$:RTLSHARE.OLB.
             Instead, the modules containing the services provided by
             ADA$FMATH.EXE are now provided either in the VAXELN object
             library ELN$:RTL.OLB or in another VAXELN-supplied image.
             ADA$FMATH.EXE is, however, still provided in the ELN$ di-
             rectory for use by previously linked programs that reference
             it.
