    zero (0).

    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error in the IBM MQ code meant that channels which have
    a negotiated SHARECNV value of zero will have a blank MCAUSER
    attribute when displayed via the runmqsc DISPLAY CHSTATUS
    command.

    value during channel startup.
