System/390 assembler-language examples

This collection of topics is mostly taken from the IBM MQ for z/OS sample applications.

• Connect to a queue manager
  This example demonstrates how to use the MQCONN call to connect a program to a queue manager in z/OS batch.
• Disconnect from a queue manager
  This example demonstrates how to use the MQDISC call to disconnect a program from a queue manager in z/OS batch.
• Create a dynamic queue
  This example demonstrates how to use the MQOPEN call to create a dynamic queue.
• Opening an existing queue
  This example demonstrates how to use the MQOPEN call to open a queue that has already been defined.
• Closing a queue
  This example demonstrates how to use the MQCLOSE call to close a queue.
• Put a message using MQPUT
  This example demonstrates how to use the MQPUT call to put a message on a queue.
• Put a message using MQPUT1
  This example demonstrates how to use the MQPUT1 call to open a queue, put a single message on the queue, then close the queue.
• Getting a message
  This example demonstrates how to use the MQGET call to remove a message from a queue.
• Getting a message using the wait option
  This example demonstrates how to use the wait option of the MQGET call.
• Getting a message using signaling
  This example demonstrates how to use the MQGET call to set a signal so that we are notified when a suitable message arrives on a queue.
• Inquiring about and setting the attributes of a queue
  This example demonstrates how to use the MQINQ call to inquire about the attributes of a queue and to use the MQSET call to change the attributes of a queue.
