Question
Command to display Console Buffer
A. D C,*
B. D C,B
C. K Q
D. $dspl
Answer
B. D C,B
Explanation
The D C,B command is used in JCL (Job Control Language) on IBM mainframe systems running z/OS to display the contents of the console buffer.
The console buffer contains a log of recent system messages and operator commands. Issuing D C,B will show this information, which can be helpful for troubleshooting or reviewing system activity.
Here’s a breakdown of the command syntax:
D = Display
C = Console
B = Buffer
The other options are incorrect:
A. D C,* would display console information but not specifically the buffer
C. K Q is not a valid z/OS command
D. $dspl is also not a valid z/OS command
So in summary, to view the contents of the console buffer showing recent messages and commands on a mainframe system, the proper JCL command to use is D C,B. Mastering JCL basics like this is crucial for excelling on the Wipro TrendNxt mainframe assessment.
