The command PRRNJCL,UPDATE=NO should show information but it comes out empty.
However, the command PRRNDEL,DAYS=0,UPDATE=NO, does list data on the screen.
This article explains why the command PRRNJCL,UPDATE=NO does not list information from Prior-Run queue.

The PRRNJCL command can list and/or delete JCL or PARM data for jobs that are in the prior-run queue and have JCL or PARM data retained.
The JCL or PARM data is retained depending on the value of the RETAIN field in the DB.1 Panel.
When RETAIN-JCL=YES the execution JCL is retained in the trailer queue after a successful run.
The jobs defined with RETAIN-JCL=NO are not retained so not displayed by the PRRNJCL command.
The command PRRNDEL,DAYS=20,UPDATE=YES will delete the jobs with an age of 20 or more days from the Prior-run queue. This will also delete JCL and PARM data for the jobs if they exist.
