To help you keep track of messages, your application programmer can also group and name messages by function. When AMRF is active, the WTO macro in MVS™ allows programs to associate a 1 to 8 alphanumeric character or “keyname” with certain messages. Operators on an MCS console can use the KEY operand on the DISPLAY R command to display all the outstanding action messages by keynames. For example, if an application programmer assigned the characters “PAYROLL” to all payroll application messages, an operator can list all the outstanding messages for payroll messages by entering the following command from an MCS console in the system or sysplex:

DISPLAY R,M,KEY=PAYROLL
