RMDL (10-digit signed integer)

Length of bulk data.

The RMDL field specifies the length of the bulk data referenced by the MQRMH structure.

If the bulk data is actually present in the message, the data begins at an offset of RMLEN bytes from the start of the MQRMH structure. The length of the entire message minus RMLEN gives the length of the bulk data present.

If data is present in the message, RMDL specifies the amount of that data that is relevant. The normal case is for RMDL to have the same value as the length of data actually present in the message.

If the MQRMH structure represents the remaining data in the object (starting from the specified logical offset), the value zero can be used for RMDL, provided that the bulk data is not actually present in the message.

If no data is present, the end of MQRMH coincides with the end of the message.

The initial value of this field is 0.
