APAR status

  • Closed as program error.

Error description

  • During initialization, APL2 tests for the presence of the
    vector facility by testing bits in the CVT and executing
    vector operation codes.  The CVT bits and vector operation
    codes are no longer valid on new hardware, and might be
    reused for other purposes some day. APl2 should not use these
    bits and operation codes.

    * USERS AFFECTED: All APL2 users.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: If in the future opcodes once used      *
    *                      for the vector facility are reused      *
    *                      for other purposes, APL2 could          *
    *                      produce incorrect answers or abend.     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The APL2 initialization code tests for the vector facility
    by looking at bits in the CVT (MVS only) and executing
    vector opcodes.  Since vector facility hardware is no longer
    in use, the initialization tests should be removed.
    

Problem conclusion

  • The initialization code for the vector facility is
    bypassed.
