Hi,
I was specifically looking for Destructive Read. I was able to get the sample Cobol Browse and Destructive Read from the MQ sample Libraries.
Can i get a sample header cmqc.h file in Z.OS library ? Could someone please point ? |

| All MQGets are destructive, unless you tell them not to be. |

What research have you done on this?
The InfoCenter, the WMQ Application Programming Reference, and the WMQ Application Programming Guide are excellent sources of information.
Research the MQGET call. Research for the MQGMO structure. Research the browse option.

"destructive" describes the treatment of a message when an application gets it from the queue:
"non-destructive" = MQGET with browse option = leave the message on the queue
"destructive" = MQGET with default options = remove the message from the queue (exact behaviour depends on syncpoint option. no-syncpoint = do it now. sycnpoint = do it later when the commit occurs, although it may be rolled back if a back-out occurs)
These treatments and syncpoint are determined by MQI programming, not by attributes of queue definitions.
