DHPRO (10-digit signed integer)

Offset of first MQPMR record from start of MQDH.

This field gives the offset in bytes of the first record in the array of MQPMR put message records containing the message properties. If present, there are DHCNT records in this array. These records (plus any bytes skipped between the first put message record and the previous field) are included in the length given by the DHLEN field.

Put message records are optional; if no records are provided, DHPRO is zero, and DHPRF has the value PFNONE.

The initial value of this field is 0.
