Outstanding reply numbers on z/OS consoles

Outstanding reply numbers are used only on z/OS® system consoles. They are used to pass input directly to IMS™. Terminals defined to IMS do not use outstanding reply numbers.

As an example, IMS might display the following on the z/OS console:

*48 DFS996I *IMS READY*

To communicate with IMS through the z/OS system console, you must reply with the outstanding reply number (in this example, the number is 48). A reply might look like this:

R 48,/START DC

After IMS responds to the command, the next outstanding reply number is displayed with the DFS996I message, as follows:

DFS058I START COMMAND COMPLETED
*49 DFS996I *IMS READY*
