CPI-C Implementers' Workshop Participants,

     A new Special Interest Group was formed at the March CIW meeting
to discuss the implementation requirements for CPI-C 2.0. The objective
of the SIG is:

          To define the implementation requirements for CPI-C in order
          to provide for orderly subsetting of the functions across
          the various platforms, and to provide an application with
          the ability to determine the functional level of the local
          implementation.

     The proposed schedule is:

           3/93 - Approved Direction
           9/93 - Approved Pages
          12/93 - Closed Pages

     The 9/93 and 12/93 dates were selected to correspond to the AP
and CP expectations of the Full Duplex, Non-blocking, OSI TP, etc.
enhancement work.

     Approved Direction status was granted by the CIW at the March
meeting for the following direction:

          1. Define a mandatory Conversation support plus
             -  optional Transaction support
             -  optional Full Duplex support
             -  optional SNA LU 6.2 Specific support
             -  optional OSI TP Specific support

             The criteria that was/will be used to identify the optional
             support groups includes:

             -  Complexity for the implementer
             -  Complexity for the user
             -  Minimize the number of optional support groups
             -  Alignment to industry profiles, e.g. IGOSS, UK GOSIP,
                  X/Open components, etc.

          2. All calls must be provided by an implementation. However,
             calls in an optional support group may be handled by
             returning a cm_function_not_supported return code value
             when that optional support group is not supported.

     As with the other CIW SIGs, a mail exploder distribution list has
been established and all interested participants are encouraged to join
in the future discussions. To join the SIG, please send a request to

          ciw-sig-conformance-request @ ibmstandards.cary.ibm.com

     An initial proposal is expected to be available through the CIW
FTP library next week. I will announce its availability via the
Conformance SIG distribution list.

     Thank you for your prompt attention.
