Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of the dmpmqmsg command who use it to transfer a large
    amount of data
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The underlying type used to store the number of written bytes
    was a signed 32-bit integer and the code also printed this
    number as a signed value so the number became negative after
    recording 2GB of data.
    
    The messages field is also affected in the same way.
    

Problem conclusion

  • The code was modified so that the fields used to track the
    number of messages and bytes now use an unsigned 64-bit type and
    are also printed as unsigned values.
    
    This is a display problem only and will not interfere with the
    operation of the dmpmqmsg command.
