Examples: Using data queues or user queues

Data queues and user queues both provide a means for one or more processes to communicate asynchronously. The queues can be processed FIFO (first-in first-out), LIFO (last-in first-out), or by key.

• Determining whether to use data queues or user queues
  If user queues and data queues supply the same function, which one should you choose for your implementation? The following is a comparison of the two and an insight into when you should use one queue rather than the other.
• Example in ILE C: Data queue
  This program illustrates how to use APIs to create and manipulate a data queue.
• Example in ILE COBOL: Data queue
  This program illustrates how to use APIs to create and manipulate a *DTAQ. The following program also works with OPM COBOL.
• Example in OPM RPG: Data queue
  This program illustrates how to use APIs to create and manipulate a *DTAQ.
• Example in ILE RPG: Data queue
  This program illustrates how to use APIs to create and manipulate a *DTAQ.
• Example in ILE C: User queue
  This program illustrates how to use APIs to create and manipulate a user queue.
