Hard-Copy log

The hard-copy log is a record of all system message traffic:

Messages to and from all consoles
Commands and replies that are entered by the operator.

In a dump, these messages appear in the master trace. With JES3, the hard-copy log is written to the SYSLOG, the OPERLOG, or both. With JES2, the hard-copy log is written to the SYSLOG, the OPERLOG, or both; it can also be viewed using a product like System Display and Search Facility (SDSF). For more information abut SDSF, see z/OS SDSF Operation and Customization.
