This is a quick walk through on how view help job output from jobs on the spooler held output queue for the TK3 and TK4- versions of MVS3.8J. It shows how to use RPF, QUEUE and REVIEW to view job output.
Note: video seems to buffer before sound, there is sound you may just need to go back to the start of the video after it has been playing for a while.
To view jobs by partial prefix in the version of Q supplied with TK3 you need to install the updated version of Queue from Greg Price's site. That updated version may already be in TK4-.
