include "ommqi.xin"
The object must be open (else external exception OMMQI0013).
max-length must be greater than or equal to zero (else external exception OMMQI0014).
This function corresponds to the MQPUT function in the MQSeries API.
The object parameter maps to both the Hconn and Hobj parameters of MQPUT.
The returned stream corresponds to the Buffer parameter of MQPUT.
The CompCode and Reason parameters of MQPUT are integrated into the OMMQI error handling.
Connect to a queue and retrieve the first message.
