Processing hardcopy

Logging provides a permanent record of system activity. Your installation can record system messages and, optionally, commands and command responses, by using the system log (SYSLOG), the operations log (OPERLOG), or both. Your installation can also allow an extended MCS console to receive the same set of messages as SYSLOG and OPERLOG. The log that receives messages is called the hardcopy medium. The group of messages that is recorded is called the hardcopy message set.

The hardcopy message set is defined at system initialization and persists for the life of the system. See z/OS MVS Planning: Operations for the characteristics of the hardcopy message set.
