Putting a message using MQPUT

 

This example demonstrates how to use the MQPUT call using context. This extract is taken from the Credit Check sample application (program CSQ4CVB1) supplied with WebSphere MQ for z/OS. For the names and locations of the sample applications on other platforms, see Sample programs (all platforms except z/OS).
