Create a dynamic queue

 

This example demonstrates how to use the MQOPEN call to create a dynamic queue. This extract is taken from the Mail Manager sample application (program CSQ4TCD1) 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).
